c# – Web Services Dynamic Invoker问题

看到这个question似乎无法修改运行时的属性,如何实现动态Web服务调用在运行时更改此属性？可能吗？

我正在寻找一种方法来执行动态调用“泛型样式”,而不是修改WebServiceBinding属性.

简而言之,这是我的班级：

using System.Web.Services;
using System.Web.Services.Protocols;

namespace Whatever {
    [WebServiceBinding(Name = "",Namespace = "")]
    public class WebServiceInvoker : SoapHttpClientProtocol {
        public WebServiceInvoker(string url,string ns,string bindingName) {

            ChangeNamespace(ns);
            ChangeBinding(bindingName);
            Url = url;
            // credentials,etc
    }
        public void ChangeNamespace(string ns) {
            var att = GetType().GetCustomAttributes(typeof (WebServiceBindingAttribute),true);         
            if (att.Length > 0) {
                // doesn't work
                ((WebServiceBindingAttribute)att[0]).Namespace = ns;
            }
        }
        private void ChangeBinding(string bindingName) {
            var att = GetType().GetCustomAttributes(typeof(WebServiceBindingAttribute),true);

            if (att.Length > 0) {
                // doesn't work
                ((WebServiceBindingAttribute)att[0]).Name = bindingName;
            }
        }
        public object[] MakeInvoke(string method,object[] args) {
            var res = Invoke(method,method);
            return res;
        }

        public TRet InvokeFunction<TRet>(string method) {
            //Funcion<T1,T2,T3,TRet>
            var res = Invoke(method,null);
            return MyUtils.ForceCast<TRet>(res);
        }
        public TRet InvokeFunction<T1,TRet>(string method,T1 par1) {
            //Funcion<T1,TRet>
            var args = new object[] { par1 };
            var res = Invoke(method,args);
            return MyUtils.ForceCast<TRet>(res);
        }
        public TRet InvokeFunction<T1,T1 par1,T2 par2) {
            //Funcion<T1,TRet>
            var args = new object[] { par1,par2 };
            var res = Invoke(method,T2 par2,T3 par3) {
            //Funcion<T1,TRet>
            var args = new object[] {par1,par2,par3};
            var res = Invoke(method,args);
            return MyUtils.ForceCast<TRet>(res);
        }

        public void InvokeAction(string metodo) {
            //Funcion<T1,TRet>
            Invoke(method,null);
        }
        public void InvokeAction<T1>(string method,TRet>
            var args = new object[] { par1 };
            Invoke(method,args);
        }
        public void InvokeAction<T1,T2>(string method,par2 };
            Invoke(method,T3>(string method,par3 };
            Invoke(method,args);
        }
    }
}

我想这样打电话给我的班级：

var miProxy = new WebServiceInvoker("http://webServiceLocation","ns","Binding");
var res = miProxy.InvokeFunction<string,string,Entity>("MyWebMethod",stringPar1,stringPar2);
