Question

我正在尝试将csv文件上传到ftp位置，但由于上述原因，它每次都会失败。

我的代码失败了：Stream requestStream = request.GetRequestStream();

private void button1_Click(object sender, EventArgs e)
        {

            // Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://100.100.100.83");
            request.Method = WebRequestMethods.Ftp.UploadFile;

            // This example assumes the FTP site uses anonymous logon.
            request.Credentials = new NetworkCredential("guardian", "roar");
            request.KeepAlive = true;
            request.UsePassive = false;
            // Copy the contents of the file to the request stream.
            StreamReader sourceStream = new StreamReader("C:/blacklists/blacklist.csv");
            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();
        }
    }
}

我遇到同样的问题，我用"ftp://100.100.100.83/"替换"ftp://ftp.xxx.com/"并且工作正常。

您的网址缺少文件名

ftp://100.100.100.83/blacklist.csv

请求的url对此ftp命令无效
