客户端动态调用WCF服务中的方法

客户端调用wcf ，有时需要动态的调用服务端的WCF中的方法，本方法，反射wcf 的接口，动态调用接口中的方法。

主要为，动态绑定，反射动态调用。

 public static object ExecuteMethod<T>(string pUrl,string pMethodName, params object[] pParams)
        {
            EndpointAddress address = new EndpointAddress(pUrl);
            Binding bindinginstance = null;
            NetTcpBinding ws = new NetTcpBinding();
            ws.MaxReceivedMessageSize = 20971520;
            ws.Security.Mode = SecurityMode.None;
            bindinginstance = ws;
            using (ChannelFactory<T> channel = new ChannelFactory<T>(bindinginstance,address))
            {
                T instance = channel.CreateChannel();
                using (instance as IDisposable)
                {
                    try
                    {
                        Type type = typeof(T);
                        MethodInfo mi = type.GetMethod(pMethodName);
                        return mi.Invoke(instance, pParams);
                    }
                    catch (TimeoutException)
                    {
                        (instance as ICommunicationObject).Abort();
                        throw;
                    }
                    catch (CommunicationException)
                    {
                        (instance as ICommunicationObject).Abort();
                        throw;
                    }
                    catch (Exception vErr)
                    {
                        (instance as ICommunicationObject).Abort();
                        throw;
                    }
                }
            }
        }

 

本文使用的是nettcpbinding 绑定方式，可修改。

调用方法使用

ExecuteMethod<IService>("net.tcp://192.168.0.1:8001/mex", "Test", new object[] { "参数" })
