这是我使用PARSE发送推送消息的应用程序代码

public static string ParseAuthenticate(string strUserName, string 
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.parse.com/1/push");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add("X-Parse-Application-Id", "my app id");
httpWebRequest.Headers.Add("X-Parse-REST-API-KEY", "my rest api key"); 
httpWebRequest.Method = "POST";
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var responseText = streamReader.ReadToEnd();
return responseText;
}
}

Request body
{
    "channels": [
      "test"
    ],
    "data": {
      "alert": "12345"
    }
  } 

上面的代码在哪里传递我的请求参数(正文)？如何将我的请求框架为JSON格式？在此先感谢.请帮我解决这个问题.
