发送 gcm 推送通知时缺少 unicode 字符

Question

我在我的 c# 代码中使用 gcm 发送推送通知。当我用英文发送数据时它工作正常。但是当数据中有任何 unicode 印地语字符时，它在 json 我在 android 设备上丢失。请帮我解决这个问题。我的代码如下-

 public string SendNotification(string deviceId, string message)
    {

        var value = message;
        WebRequest tRequest;
        tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
        tRequest.Method = "post";
        tRequest.ContentType = " application/x-www-form-urlencoded;charset=unicode UTF-8";
        tRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));

        tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));

        string postData = "delay_while_idle=1&data.data=" + value + "&registration_id=" + deviceId + "";
        Console.WriteLine(postData);
        Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
        tRequest.ContentLength = byteArray.Length;

        Stream dataStream = tRequest.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        dataStream.Close();

        WebResponse tResponse = tRequest.GetResponse();

        dataStream = tResponse.GetResponseStream();

        StreamReader tReader = new StreamReader(dataStream);

        String sResponseFromServer = tReader.ReadToEnd();

        tReader.Close();
        dataStream.Close();
        tResponse.Close();
        return sResponseFromServer;
    }

分析代码才知道是编码的问题。然后通过在我的代码中更改下面的行-

 string postData = "delay_while_idle=1&data.data=" + value + "&registration_id=" + deviceId + "";

到

 string postData = "delay_while_idle=1&data.data=" +  HttpUtility.UrlEncode(value) + "&registration_id=" + deviceId + "";

它工作正常。我把它贴在这里是因为我认为它可以帮助其他有此类问题的人。
