1.2.2 提高代码效率之强大的RequestUtility类

对于这样的http://www.3wto.com/aspx/PictureDetail.aspx?ID=8719，你会怎么取得ID值呢？

如果你还停留在:

      if(Request.QueryString("ID")!=null){

            int ID = Convert.ToInt32(Request.QueryString("ID"));

     }

那你在这篇文章将会找到新的答案，比如：

     int ID = RequestUtility.GetQueryInt("ID",-1); 

怎么样，是不是很easy?

OK 下面还有更精彩的，fllow me!
