Question

我有一段非常简单的代码。一切都写得正确，没有拼写错误，而且我和同事一起讨价还价，但我们两个人根本就没有错误在哪里。

它会顺利地通过getRequestStream（）来弹出异常。它找到文件，正确编码，但似乎无法与服务器连接。

这是代码：

public class WebRequestUploadExample
{
    public  void WebRequestUpload()
    {


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

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

        // Copy the contents of the file to the request stream.
        StreamReader sourceStream = new StreamReader(@"D:\ftpTest\Test\Test.txt");
        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();

    }
}

可能是您的目标服务器不支持＆＃39;被动＆＃39;模式。你尝试过主动模式吗？ request.UsePassive = false;

FtpWebRequest.UsePassive

此Web命令的FTP WebException-URI无效
