Question

我试图上传文件，但是我收到了以下未处理的例外情况。

未处理的类型＆＃39; System.Net.WebException＆＃39;发生在System.dll
中

当它到达以下行时会发生错误：

 using (var requestStream = request.GetRequestStream())

以下是我的主叫代码：

 UploadFileToFtp(@"C:\file.txt", "xyx@abc.com", "foobar");

方法：

public static void UploadFileToFtp(string filePath, string username, string password)
{
    var fileName = Path.GetFileName(filePath);
    var request = (FtpWebRequest)WebRequest.Create("ftp://ftp.alphabeta.com/" + fileName);

    request.Method = WebRequestMethods.Ftp.UploadFile;
    request.Credentials = new NetworkCredential(username, password);
    request.UsePassive = true;
    request.UseBinary = true;
    request.KeepAlive = false;

    using (var fileStream = File.OpenRead(filePath))
    {
        using (var requestStream = request.GetRequestStream())
        {
            fileStream.CopyTo(requestStream);
            requestStream.Close();
        }
    }

    var response = (FtpWebResponse)request.GetResponse();
    Console.WriteLine("Upload done: {0}", response.StatusDescription);
    response.Close();
}

我可以使用FileZilla和WSFTP使用登录信息访问Web服务器：

FTP / SSL自动检测

以下是例外情况：
