Renaming file with FtpWebRequest

问题:

When moving a file to another FTP location you must use RenameTo with the new FTP location.

In this example how do you use RenameTo to move to the new FTP location?

FtpWebRequest ftpRequest = null;
FtpWebResponse ftpResponse = null;
try
{
    ftpRequest = (FtpWebRequest)WebRequest.Create("ftp://mysite.com/folder1/fileName.ext");
    ftpRequest.Credentials = new NetworkCredential("user", "pass");
    ftpRequest.UseBinary = true;
    ftpRequest.UsePassive = true;
    ftpRequest.KeepAlive = true;
    ftpRequest.Method = WebRequestMethods.Ftp.Rename;
    ftpRequest.RenameTo = "ftp://mysite.com/folder2/fileName.ext";
    ftpResponse = (FtpWebResponse)ftpRequest.GetResponse();
    ftpResponse.Close();
    ftpRequest = null;
}
catch (Exception ex) { Label1.Text = (ex.ToString()); }

回答1:

Set a target path to .RenameTo property, not URL:

ftpRequest.RenameTo = "/folder2/fileName.ext";

As per MSDN documentation for FtpWebRequest.RenameTo property:

Gets or sets the new name of a file being renamed.

Compare to WebRequest.Create method:

Initializes a new WebRequest instance for the specified URI scheme.

A- change it to be

ftpRequest = (FtpWebRequest)WebRequest.Create("ftp://mysite.com//folder1/fileName.ext");

B- ftpRequest.RenameTo = "ftp://mysite.com//folder2/fileName.ext";

Just add (/) before your file folder that allow you to delFile,renFile also downLoadFile
