调用

string url = "http://webservice.webxml.com.cn/WebServices/TrainTimeWebService.asmx";
            string[] args = new string[2];
            args[0] = "k123";
            args[1] = "";

            DataSet ds = (DataSet)result;
            this.GridView1.DataSource = ds;
            this.GridView1.DataBind();
