Windows phone 7 如何使用Windows 7 Phone SDK发出此请求

您好，我有以下jQuery.post示例，需要知道如何使用Windows 7 phone SDK发出相同的请求

任何建议或指点都将受到欢迎

jQuery.post('http://URL',{
      'key':'4ec6975151b8ea0d768f8599541e2ee30fb20a93',
      'function':'getGroupMembers',
      'parameters':{    
        "group":{
            'group_id':'44',
            'user_id':'100003167624583'
        }
    }      
  },
function(res){
   console.log(res);   
},'json');

将发布一个字符串并返回结果。您可以使用（通过NuGet或手动下载）序列化/反序列化：

WebClient client = new WebClient();

client.UploadStringCompleted += (s,e) =>
{
    var children = JToken.Parse(e.Result)["some_json_property"].Children();
    // continue here (but remember this is all asynchronous)
};

client.UploadStringAsync(
    new Uri("http://URI"),
    "POST",
    JsonConvert.SerializeObject(new
    {
        key = "4ec6975151b8ea0d768f8599541e2ee30fb20a93",
        function = "getGroupMembers",
        parameters = new {    
            group = {
                group_id = "44",
                user_id = "100003167624583"
            }
        }
    }));
