Question

我搜索了这个，并遇到了很多教程，这很好，但我得到一个小错误“远程服务器返回错误：（550）文件不可用（例如，文件未找到，无法访问）。”

这是我的代码



 try
            {
                // Get the object used to communicate with the server.
                FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + "XXX.XXX.XX.XXX/array1/Despatch");
                request.Method = WebRequestMethods.Ftp.UploadFile;

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

                // Copy the contents of the file to the request stream.
                StreamReader sourceStream = new StreamReader(Server.MapPath(System.Configuration.ConfigurationManager.AppSettings["DespatchExpressData"]));
                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();
            }
            catch (WebException e)
            {
                String status = ((FtpWebResponse)e.Response).StatusDescription;
            }

try { // Get the object used to communicate with the server. FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + "XXX.XXX.XX.XXX/array1/Despatch"); request.Method = WebRequestMethods.Ftp.UploadFile; // This example assumes the FTP site uses anonymous logon. request.Credentials = new NetworkCredential("UserName", "Password"); // Copy the contents of the file to the request stream. StreamReader sourceStream = new StreamReader(Server.MapPath(System.Configuration.ConfigurationManager.AppSettings["DespatchExpressData"])); 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(); } catch (WebException e) { String status = ((FtpWebResponse)e.Response).StatusDescription; }

在调用上面的方法之前，创建一个文本文件并保存在我的项目解决方案DispatchDetails中的文件夹中，txt文件被称为Data.txt im，使用StreamReader获取txt文件，然后尝试将其上传到文件夹在FTP帐户

我甚至尝试对流读取器部分进行硬编码并仍然得到错误：（

它落在这一行

Stream requestStream = request.GetRequestStream();

任何帮助都将受到高度赞赏！

谢谢。

看看here

可能您必须为WebRequest.Create设置正确的URI，例如

WebRequest.Create("ftp://" + "XXX.XXX.XX.XXX//array1/Despatch");

当然，检查一下，如果你有权写：）

通过FTP c＃将txt文件上传到服务器上的文件夹
