使用FTP協議上傳後文件損壞

我試圖使用FTP協議將一些* .wav文件上傳到主機。但事情是，上傳後的文件非常破壞！文件的大小與本地文件相同，我可以在損壞的文件中聽到某些內容，但噪聲被添加到* .wav文件中。這是他的代碼我用我的文件上傳到服務器：使用FTP協議上傳後文件損壞

public void UploadViaFtp(Object fn) 
    { 
     string filename = (string)fn; 
     // Get the object used to communicate with the server. 
     FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.****.com/htdocs/uploads/" + filename + ".wav"); 
     request.Method = WebRequestMethods.Ftp.UploadFile; 

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

     // Copy the contents of the file to the request stream. 
     StreamReader sourceStream = new StreamReader(filename + ".wav"); 
     byte[] fileContents = Encoding.Default.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(); 

     this.Dispatcher.Invoke((Action)(() => box.Text += "\nFile \"" + filename + "\" Uploaded Successfully!!!")); 

     response.Close(); 
    }

，如果它是有用的，這是記錄聲音文件我的代碼：

[DllImport("winmm.dll", EntryPoint = "mciSendStringA", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)] 
    private static extern int mciSendString(string lpstrCommand, string lpstrReturnString, int uReturnLength, int hwndCallback); 

    struct RecUploadStruct 
    { 
     public DateTime timeForNaming; 
    } 

    public void RecUpload(Object param) 
    { 
     RecUploadStruct iParam = (RecUploadStruct)param; 

     mciSendString("open new Type waveaudio Alias recsound", "", 0, 0); 
     mciSendString("record recsound", "", 0, 0); 
     Console.WriteLine("recording, press Enter to stop and save ..."); 

     Thread.Sleep(1000); 

     string name = iParam.timeForNaming.Day.ToString() + iParam.timeForNaming.Hour.ToString() + iParam.timeForNaming.Minute.ToString() + iParam.timeForNaming.Second.ToString(); 

     mciSendString("save recsound " + name + ".wav", "", 0, 0); 
     mciSendString("close recsound ", "", 0, 0); 

     Thread uploader = new Thread(UploadViaFtp); 

     uploader.Start(name); 
    }

，這是某些文件上傳前： before

，這是上傳後的文件： after

請幫助我解決任何問題或建議。謝謝。

你可能不應該在代碼中包含真正的憑據。 – 2015-02-11 18:52:50

謝謝@ReticulatedSpline。 – ConductedClever 2015-02-11 18:55:45

您必須將您的Ftp請求設置爲二進制request.UseBinary至true。

request.UseBinary = true;

我檢查過。它沒用！ – ConductedClever 2015-02-11 19:01:54

@ConductedClever爲什麼不呢？ – Jens 2015-02-11 19:02:31

聲音仍然很嘈雜。如果你想我給你的聲音！ – ConductedClever 2015-02-11 19:04:54
