HttpRequest的GET，POST请求封装_httprequest.createpost

调用如下：

  var result = HttpHelper.GetResponseString(HttpHelper.CreatePostHttpResponse(url, dic, 0, null));
1

其中，url是请求地址，dic 是实例化的字典值。

封装的HttpHelper如下：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
