C#可用：
若该字符串是使用Http Get发送，url?a=1&b=2&c=3，使用下边代码即可获取参数a的值：
程序代码
Request.QueryString["a"]
若该字符串是远程接口返回，以前都是用Split函数去拆分，今天发现一个非常强大的方法ParseQueryString，简单多了：
程序代码
<%@ WebHandler Language="C#" class="Default" %> using System; using System.Web; using System.Text; using System.Collections.Specialized; public class Default : IHttpHandler { public void ProcessRequest (HttpContext context) { context.Response.ContentType = "text/plain"; string str = "a=1&b=2&c=3"; NameValueCollection query = HttpUtility.ParseQueryString(str, Encoding.GetEncoding("gb2312")); context.Response.Write(query["a"]); } public bool IsReusable { get { return false; } } }
C#例子代码：
resultDescription = resultDescription.Replace("<br>", "&"); NameValueCollection query = HttpUtility.ParseQueryString(resultDescription, Encoding.GetEncoding("gb2312")); responseModel.MicroPayRequestModel = new Models.RequestModel.MicroPayRequestModel(); responseModel.MicroPayRequestModel.Appid = query["appid"];
responseModel.MicroPayRequestModel.XXX= query["XXX"];
