c# - ftp 损坏 exe 和 dll 文件 (C#)

Question

我有以下代码用于从服务器下载文件，适用于文本文件。代码取自 MSDN 示例:

public void DownloadFile(string serverPath, string localPath)
        {

            try
            {
                FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + serverPath);

                request.Method = WebRequestMethods.Ftp.DownloadFile;
                request.Credentials = new NetworkCredential(_domain + "\\" + _username, _password);
                FtpWebResponse response = (FtpWebResponse)request.GetResponse();
                Stream responseStream = response.GetResponseStream();
                StreamReader reader = new StreamReader(responseStream);
                string contents = reader.ReadToEnd();
                File.WriteAllText(localPath, contents);

                reader.Close();
                response.Close();

            }
            catch (WebException ex)
            {                
                string exMsg = string.Empty;


                //add more error codes               
                FtpWebResponse response = (FtpWebResponse)ex.Response;
                MessageBox.Show(response.StatusCode.ToString());

                switch(response.StatusCode) {
                    case  FtpStatusCode.NotLoggedIn:
                        exMsg = "wrong password";
                        break;

                    case FtpStatusCode.ActionNotTakenFileUnavailable:
                        exMsg = "file you are trying to load is not found";
                        break;

                    default:
                        exMsg = "The server is inaccessible or taking too long to respond.";
                        break;
                }   

                throw new Exception(exMsg);
            }

            return;
        }

但是，它会破坏 dll 和 exe。知道这里的罪魁祸首是什么吗？

试试看:

request.UseBinary = true;
