ftpwebrequest上传

㈠ C# winform如何实现批量上传文件到远程服务器

基本思路是远程服务器假设ftp，本地用System.Net.FtpWebRequest建立Ftp客户端，用NetworkCredential.NetworkCredential建立用户名和密码验证方式，用System.Net.WebRequestMethods.Ftp设置上传和下载命令，文件通过FileStream流进行发送和接收。

㈡ FtpWebRequest 多个文件同时上传。求C#代码，举个栗子就好。

#
usingSystem;
usingSystem.IO;
usingSystem.Net;
namespaceFtp
{
classProgram
{
staticvoidMain(string[]args)
{
DirectoryInfodir=newDirectoryInfo("upload");//上传文件所在的目录
FileInfo[]fileInfos=dir.GetFiles();
foreach(FileInfoiteminfileInfos)//遍历目录下的所有文件
{
UploadFile(item);//开始上传
}
Console.WriteLine("done!");
}
privatestaticvoidUploadFile(FileInfofi)
{
FileStreamfs=fi.OpenRead();
longlength=fs.Length;
FtpWebRequestreq=(FtpWebRequest)WebRequest.Create(newUri("ftp://192.168.56.1/"+fi.Name));
req.Credentials=newNetworkCredential("name","password");
req.Method=WebRequestMethods.Ftp.UploadFile;
req.UseBinary=true;
req.ContentLength=length;
req.Timeout=10*1000;
try
{
Streamstream=req.GetRequestStream();
intBufferLength=2048;
byte[]b=newbyte[BufferLength];
inti;
while((i=fs.Read(b,0,BufferLength))>0)
{
stream.Write(b,0,i);
}
stream.Close();
stream.Dispose();
}
catch(Exceptionex)
{
Console.WriteLine(ex.ToString());
}
}
}
}

㈤ VB6.0 FTP下载上传问题【可加分！】

首先介绍ftp下载，代码如下： Const Str_FtpServer As String = " ftp://ftp.lob.cn" Private Str_Username As String = "lob" Private Str_Password As String = "xxxxxxxx" Private Sub DownloadFile(ByVal Str_Path As String) Try Dim Str_Filename As String = Str_Path Dim ftpReq As FtpWebRequest = WebRequest.Create(Str_Filename) ftpReq.Method = WebRequestMethods.Ftp.DownloadFile ftpReq.Credentials = New NetworkCredential(Str_Username, Str_Password) Dim FTPResp As FtpWebResponse = ftpReq.GetResponse Dim ftpRespStream As Stream = FTPResp.GetResponseStream 'FTPResp.StatusDescription 为回显状态的描述 可用于调试 ftpRespStream.Save("d:\lobdotcn.rar") '保存到本地的路径,如果你乐意也可以直接定义到参数中 FTPResp.Close() Catch ex As Exception MsgBox(ex.Message) End Try End Sub 调用方式：DownloadImage(Str_FtpServer& "/logo.jpg")==============================================================你先看看是你想要的不？是的话再往下看从这里过来的： http://blog.chinaunix.net/u/22170/showart_475726.html 呵呵我是做C#的，但是看你这分数实在太诱人，就帮你找了找~
