调用自定义的方法接口.ashx一般处理程序 借鉴了别人网页抓取的类

描述：近段时间写接口，还要调用别人的接口，写好写但是调用不知道啊！刚开始也知道怎么开始，感觉简单不就是调用吗？但是实施起来，汗...对我一个新手来说第一次接触，所以也是自学成才吧！下次登录的时候把源码带上....

 

//源码

string jsonStr = Tools.Tool.getHttpRequestweb( "你获得的接口地址" );
string sttNumber = Tools.Tool.GetTransData(jsonStr);

///

/// 解析JSON数据
///
///
///
public static string GetTransData( string jsonText)
{
     JavaScriptSerializer s = new JavaScriptSerializer();
            Dictionary< string , object > JsonData = (Dictionary< string ,      object >)s.DeserializeObject(jsonText);
            Dictionary< string , object > trades_sold_get_response = (Dictionary< string , object >)JsonData;
            return trades_sold_get_response[ "code" ].ToString();
 }

if (sttNumber == "1" )
{
//我这儿1代表的是成功
}
