c# - 如何使用 C# 创建 Windows 服务器以通过 FTP 传输文件

Question

如何使用 C# 创建 Windows 服务器以通过 FTP 传输文件？我有一个文件夹，每 x 分钟由我的 ERP 系统生成的 xml 文件提供...我需要通过 FTP 发送到我的外部服务器。我认为每 30 分钟运行一次 Windows 服务并循环浏览此文件夹中的所有文件并通过 FTP 发送就足够了。你能帮助我吗？有什么例子吗？使用 .net vs2k8 是我的开发环境。非常感谢

Answer 1

How to transfer the file is in the answer from Aghilas

I would create it as a Service so you can have it auto start

Rather than poll the directory you can just use

FileSystemWatcher Class

Maybe log any failed uploads

Answer 2

您可以尝试使用此代码

            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://....");
            request.Method = WebRequestMethods.Ftp.UploadFile;

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

            // Copy the contents of the file to the request stream.
            StreamReader sourceStream = new StreamReader("testfile.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();
