使用FTPWebRequest上传期间"请求的URI无效"

Question

我尝试将文件上传到FTP服务器上的目录.我用这个方法FtpWebRequest.我想将一个文件上传到该用户的主目录,但我总是收到以下错误消息:

请求的URI对此FTP命令无效.

有什么问题？我试过关闭被动模式,但它仍然是一样的.

static void FtpUpload()
{


    // Get the object used to communicate with the server.
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://12.22.44.45");
    request.Method = WebRequestMethods.Ftp.UploadFile;
    request.UsePassive = false;

    // This example assumes the FTP site uses anonymous logon.
    request.Credentials = new NetworkCredential("pokus", "password");

    // Copy the contents of the file to the request stream.
    StreamReader sourceStream = new StreamReader(path);
    byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
    sourceStream.Close();
    request.ContentLength = fileContents.Length;

    Stream requestStream = request.GetRequestStream();
    requestStream.Write(fileContents, 0, fileContents.Length);
    requestStream.Close();

    FtpWebResponse response = (FtpWebResponse)request.GetResponse();

    Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);

    response.Close();

}

如果要上传某些内容,则必须为FTPClient提供文件名.

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://12.22.44.45/myNewFile.dat");
