C#之ftp- 该实例所需要的引用:

c#FTP操作类,包含上传,下载,删除,获取FTP文件列表文件夹等Hhelp类,

C#之ftp- 该实例所需要的引用:

一:引用

using System;  
using System.Collections.Generic;  
using System.Text;  
using System.IO;  
using System.Net;
using System.Text.RegularExpressions;

二:命名空间及字段

namespace DotNet.Utilities
{
    public class FTPHelper
    {
        #region 字段
        string ftpURI;
        string ftpUserID;
        string ftpServerIP;
        string ftpPassword;
        string ftpRemotePath;
        #endregion

        /// <summary>  
        /// 连接FTP服务器
        /// </summary>  
        /// <param name="FtpServerIP">FTP连接地址</param>  
        /// <param name="FtpRemotePath">指定FTP连接成功后的当前目录, 如果不指定即默认为根目录</param>  
        /// <param name="FtpUserID">用户名</param>  
        /// <param name="FtpPassword">密码</param>  
        public FTPHelper(string FtpServerIP, string FtpRemotePath, string FtpUserID, string FtpPassword)
        {
            ftpServerIP = FtpServerIP;
            ftpRemotePath = FtpRemotePath;
            ftpUserID = FtpUserID;
            ftpPassword = FtpPassword;
            ftpURI = "ftp://"   ftpServerIP   "/"   ftpRemotePath   "/";
        }

 

三:ftp上传文件实例代码,只需要传递相对应的文件名,调用该方法即可

       

 /// <summary>  
        /// 上传  
        /// </summary>   
        public void Upload(string filename)
        {
            FileInfo fileInf = new FileInfo(filename);
            FtpWebRequest reqFTP;
            reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpURI   fileInf.Name));
            reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
            reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
            reqFTP.KeepAlive = false;
            reqFTP.UseBinary = true;
            reqFTP.ContentLength = fileInf.Length;
            int buffLength = 2048;
            byte[] buff = new byte[buffLength];
            int contentLen;
            FileStream fs = fileInf.OpenRead();
            try
            {
                Stream strm = reqFTP.GetRequestStream();
                contentLen = fs.Read(buff, 0, buffLength);
                while (contentLen != 0)
                {
                    strm.Write(buff, 0, contentLen);
                    contentLen = fs.Read(buff, 0, buffLength);
                }
                strm.Close();
                fs.Close();
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }

四:ftp下载之实例代码,只需要传递相对应的文件路径,文件名,调用该方法即可完成

       

/// <summary>  
        /// 下载  
        /// </summary>   
        public void Download(string filePath, string fileName)
        {
            try
            {
                FileStream outputStream = new FileStream(filePath   "\"   fileName, FileMode.Create);
                FtpWebRequest reqFTP;
                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpURI   fileName));
                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
                reqFTP.Method = WebRequestMethods.Ftp.DownloadFile;
                reqFTP.UseBinary = true;
                FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                Stream ftpStream = response.GetResponseStream();
                long cl = response.ContentLength;
                int bufferSize = 2048;
                int readCount;
                byte[] buffer = new byte[bufferSize];
                readCount = ftpStream.Read(buffer, 0, bufferSize);
                while (readCount > 0)
                {
                    outputStream.Write(buffer, 0, readCount);
                    readCount = ftpStream.Read(buffer, 0, bufferSize);
                }
                ftpStream.Close();
                outputStream.Close();
                response.Close();
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }

五:ftp删除文件之实例代码,有上传和下载,必然就会有删除,依旧简单,传入文件名即可完成删除

        /// <summary>  
        /// 删除文件  
        /// </summary>  
        public void Delete(string fileName)
        {
            try
            {
                FtpWebRequest reqFTP;
                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpURI   fileName));
                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
                reqFTP.Method = WebRequestMethods.Ftp.DeleteFile;
                reqFTP.KeepAlive = false;
                string result = String.Empty;
                FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                long size = response.ContentLength;
                Stream datastream = response.GetResponseStream();
                StreamReader sr = new StreamReader(datastream);
                result = sr.ReadToEnd();
                sr.Close();
                datastream.Close();
                response.Close();
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }

 

六:ftp获取列表之实例代码,获取当前目录下明细(包含文件和文件夹) ,这个可能用的不多,但也是需要了解的

      

  /// <summary>  
        /// 获取当前目录下明细(包含文件和文件夹)  
        /// </summary>  
        public string[] GetFilesDetailList()
        {
            try
            {
                StringBuilder result = new StringBuilder();
                FtpWebRequest ftp;
                ftp = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpURI));
                ftp.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
                ftp.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
                WebResponse response = ftp.GetResponse();
                StreamReader reader = new StreamReader(response.GetResponseStream());
                string line = reader.ReadLine();
                line = reader.ReadLine();
                line = reader.ReadLine();
                while (line != null)
                {
                    result.Append(line);
                    result.Append("n");
                    line = reader.ReadLine();
                }
                result.Remove(result.ToString().LastIndexOf("n"), 1);
                reader.Close();
                response.Close();
                return result.ToString().Split('n');
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }

七:ftp之实例代码,获取FTP文件列表(包括文件夹)

       

 /// <summary>  
        /// 获取FTP文件列表(包括文件夹)
        /// </summary>   
        private string[] GetAllList(string url)
        {
            List<string> list = new List<string>();
            FtpWebRequest req = (FtpWebRequest)WebRequest.Create(new Uri(url));
            req.Credentials = new NetworkCredential(ftpPassword, ftpPassword);
            req.Method = WebRequestMethods.Ftp.ListDirectory;
            req.UseBinary = true;
            req.UsePassive = true;
            try
            {
                using (FtpWebResponse res = (FtpWebResponse)req.GetResponse())
                {
                    using (StreamReader sr = new StreamReader(res.GetResponseStream()))
                    {
                        string s;
                        while ((s = sr.ReadLine()) != null)
                        {
                            list.Add(s);
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                throw (ex);
            }
            return list.ToArray();
        }

八:ftp创建文件夹之实例代码,如何创建文件夹

       

 /// <summary>  
        /// 创建文件夹  
        /// </summary>   
        public void MakeDir(string dirName)
        {
            FtpWebRequest reqFTP;
            try
            {
                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpURI   dirName));
                reqFTP.Method = WebRequestMethods.Ftp.MakeDirectory;
                reqFTP.UseBinary = true;
                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
                FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                Stream ftpStream = response.GetResponseStream();
                ftpStream.Close();
                response.Close();
            }
            catch (Exception ex)
            { }
        }

九:ftp之指定文件大小 ,依旧只需要提供文件名即可

      

  /// <summary>  
        /// 获取指定文件大小  
        /// </summary>  
        public long GetFileSize(string filename)
        {
            FtpWebRequest reqFTP;
            long fileSize = 0;
            try
            {
                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpURI   filename));
                reqFTP.Method = WebRequestMethods.Ftp.GetFileSize;
                reqFTP.UseBinary = true;
                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
                FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                Stream ftpStream = response.GetResponseStream();
                fileSize = response.ContentLength;
                ftpStream.Close();
                response.Close();
            }
            catch (Exception ex)
            { }
            return fileSize;
        }

十:ftp之更改文件名,传递当前文件名和新文件名即可

       

 /// <summary>  
        /// 更改文件名  
        /// </summary> 
        public void ReName(string currentFilename, string newFilename)
        {
            FtpWebRequest reqFTP;
            try
            {
                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpURI   currentFilename));
                reqFTP.Method = WebRequestMethods.Ftp.Rename;
                reqFTP.RenameTo = newFilename;
                reqFTP.UseBinary = true;
                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
                FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                Stream ftpStream = response.GetResponseStream();
                ftpStream.Close();
                response.Close();
            }
            catch (Exception ex)
            { }
        }

十一:ftp之移动文件,这个用的不是很多,但是有时候也是经常用到的,当前路径,新路径即可,这里要用绝对路径哦

        /// <summary>  
        /// 移动文件  
        /// </summary>  
        public void MovieFile(string currentFilename, string newDirectory)
        {
            ReName(currentFilename, newDirectory);
        }


    }
}

哈哈,总结了这么多,希望给需要的人一些帮助,当然还有一些其他的方法我就不一一列出来了,多行多努力!与大家共勉

            reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
            reqFTP.KeepAlive = false;
            reqFTP.UseBinary = true;
            reqFTP.ContentLength = fileInf.Length;
            int buffLength = 2048;
            byte[] buff = new byte[buffLength];
            int contentLen;
            FileStream fs = fileInf.OpenRead();
            try
            {
                Stream strm = reqFTP.GetRequestStream();
                contentLen = fs.Read(buff, 0, buffLength);
                while (contentLen != 0)
                {
                    strm.Write(buff, 0, contentLen);
                    contentLen = fs.Read(buff, 0, buffLength);
                }
                strm.Close();
                fs.Close();
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }

四:ftp下载之实例代码,只需要传递相对应的文件路径,文件名,调用该方法即可完成
