如何从Ftp服务器下载.dll文件 [英] How To download .dll file from Ftp server

问题描述

你好朋友，



我想直接从FTP服务器下载.dll文件到我的本地系统。如何使用C＃来做到这一点。



我尝试使用下面的代码，但我得到例外，例如无法从传输连接读取数据：现有连接被远程主机强行关闭。< br $>


Uri url = new Uri（@ftp：//+ ftpServerIP）;

if（url.Scheme == Uri.UriSchemeFtp ）

{

FtpWebRequest objRequest =（FtpWebRequest）FtpWebRequest.Create（url）;

//如果需要设置凭证，否则请注释此凭据代码

NetworkCredential objCredential = new NetworkCredential（ftpUserID，ftpPassword）;

objRequest.Credentials = objCredential;

objRequest.UsePassive = true;

objRequest.UseBinary = true;

objRequest.KeepAlive = false;

//objRequest.ProtocolVersion = HttpVersion.Version10;

objRequest.Ser vicePoint.ConnectionLimit = 1;

objRequest.Method = WebRequestMethods.Ftp.DownloadFile;

FtpWebResponse objResponse =（FtpWebResponse）objRequest.GetResponse（）;

StreamReader objReader = new StreamReader（objResponse.GetResponseStream（））;

byte [] buffer = new byte [16 * 1024];

int len = 0;

FileStream objFS =新的FileStream（strMainPath +\\\\ _7.dll，FileMode.Create，FileAccess.Write，FileShare.Read）;

while（（len = objReader.BaseStream.Read（buffer，0，buffer.Length））！= 0）

{

objFS.Write（buffer，0，len）;

}

objFS.Close（）;

objResponse.Close（）;

}



请帮帮我。

解决方案

您可以使用edtFTPnet开源dll将文件从FTP下载到您的计算机。创建与FTP的连接，稍后您可以使用C＃代码从FTP上传，下载和删除文件。
