Renaming file with FtpWebRequest

Question

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()); }

Solution

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.

The URL would be redundant in RenameTo, as you cannot use it to "rename" the file to another server.
