c# 如何从ftp上复制⼀除去ftp上的某个文件？

用FTPRush登陆FTP，选中文件右击删除

using System.IO;
using System.Net;

private void button2_Click(object sender, EventArgs e)
{
FtpWebRequest req;
req = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://**.**.**.**/shiyan.txt"));
req.Credentials = new NetworkCredential(ftpUserName, ftpPwd);
req.KeepAlive = false;
req.Method = WebRequestMethods.Ftp.DeleteFile;
req.UseBinary = true;

using (FtpWebResponse Response = (FtpWebResponse)req.GetResponse())
{
long size = Response.ContentLength;
using (Stream datastream = Response.GetResponseStream())
{
using (StreamReader sr = new StreamReader(datastream))
{
sr.ReadToEnd();
sr.Close();
}
datastream.Close();
}
Response.Close();
}
}
