调用方法：

            string _url = "http://localhost:26711/Index.asmx";
            TCMDSS_DEMO.Common.WebServiceAgent agent = new TCMDSS_DEMO.Common.WebServiceAgent(_url);
            object[] args = new object[3];
            args[0] = "GetProductRegister";
            args[1] = "037055098037050050083101114105097108078111037050050037051097037050050051050051049050037050050037055100";
            args[2] = "";
            string text = agent.Invoke("CallCenter", args).ToString();
            MessageBox.Show(text);
