【问题描述】：

尝试查找文件并将其上传到 ftp 服务器，我想我一切都正确，但它没有上传任何内容

string filepath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
        DirectoryInfo d = new DirectoryInfo(filepath);

        List<String> allDatfiles = Directory
               .GetFiles(filepath, "data.dat", SearchOption.AllDirectories).ToList();

        foreach (string file in allDatfiles)
        {
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.test.com/Holder");
                request.Method = WebRequestMethods.Ftp.UploadFile;

                request.Credentials = new NetworkCredential("User", "Pass");
                request.UseBinary = true;
                request.UsePassive = true;
                byte[] data = File.ReadAllBytes(file); // Think the problem is with file
                request.ContentLength = data.Length;
                Stream stream = request.GetRequestStream();
                stream.Write(data, 0, data.Length);
                stream.Close();

       }

还尝试使用 @"C... 将文件位置作为字符串放入我没有收到任何错误，上传后没有文件显示

【问题讨论】：

您是否尝试过在调试器中运行代码并在运行时检查变量内容？我们从这里看不到它们，也不知道文件是否在您要查找的位置。您将不得不自己调试它以查看失败的原因。
是的，文件在那个位置，甚至尝试使用具有特定名称的文本文件，但没有任何效果
调试器不会抛出任何错误
我没有说“抛出错误”。请阅读我写的内容。我们无法单步执行代码来查看发生了什么问题，因为我们无法看到它在运行时在做什么。只有您可以这样做，因为只有您有权访问它。

您是否检查了服务器上的用户权限.. 用户可以写入目录？

如果你使用linux服务器this will help you to fix file path issue.

     private static void UploadFile(string dir, Uri target, string fileName, string username, string password, string finilizingDir, string startupPath, string logFileDirectoryName)
            {
                try
                {
                    // Get the object used to communicate with the server.
                    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(target);
                    request.Proxy = null;
                    request.Method = WebRequestMethods.Ftp.UploadFile;

                    // logon.
                    request.Credentials = new NetworkCredential(username, password);

                    // Copy the contents of the file to the request stream.
                    StreamReader sourceStream = new StreamReader(dir + "\\" + fileName);
                    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();

                    if (response.StatusCode == FtpStatusCode.ClosingData)
                    {
                       Console.WriteLine(" --> Status Code is :" + response.StatusCode);
                    }

                     Console.WriteLine(" --> Upload File Complete With Status Description :" + response.StatusDescription);

                    response.Close();
                }
                catch (Exception ex)
                {
                     Console.WriteLine("*** Error Occurred while uploading file :" + fileName + " System Says :" + ex.Message + " **********END OF ERROR**********");
                }
            }
