UDP客戶端錯誤 - 無法發送數據字節

Question

我正在寫一個C＃P2P視頻聊天（我的考試的一部分在教師），我有點卡住通過udp發送數據。所以這裏它是如何工作的。我有一個Web_Capture庫，每一個拍攝圖像時都會將PictureBox的圖像捕獲的一個

private void webCamCapture_ImageCaptured(object source, WebCam_Capture.WebcamEventArgs e) 
     { 
      myCamera.Image = e.WebCamImage; 
      sendData(ref ipep2); // send it immediately 
     } 

所以後來SendData方法開始發送...

private void sendData(ref IPEndPoint sender) 
     { 
      byte[] data; 

      if (friendsClient == null) 
      { 
       friendsClient = new UdpClient(); 

      } 

      MemoryStream myStream = new MemoryStream(); 
      myCamera.Image.Save(myStream, System.Drawing.Imaging.ImageFormat.Jpeg); 
      data = myStream.GetBuffer(); 
      friendsClient.Send(data, data.Length,sender); 

     } 

當我調試，插座異常彈出：

System.Net.Sockets.SocketException was unhandled by user code 
    Message=The requested address is not valid in its context 
    Source=System 
    ErrorCode=10049 
    NativeErrorCode=10049 

是這樣，沒有人有任何想法，我會心存感激，如果他支持與代碼的想法，因爲我在C＃:)在此先感謝我nooby。馬裏安

應指定reciever的IP和端口，Here is a complete example

，所以你應該改變你的實現

private void sendData(ref IPEndPoint reciever) 
{ 
    byte[] data; 

    Socket sending_socket = new Socket(AddressFamily.InterNetwork, ocketType.Dgram, ProtocolType.Udp); 

    MemoryStream myStream = new MemoryStream(); 
    myCamera.Image.Save(myStream, System.Drawing.Imaging.ImageFormat.Jpeg); 
    data = myStream.GetBuffer(); 
    sending_socket.SendTo(data, reciever); 
}
