动态调用WCF服务

Posted 2020-08-17 castlooo

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" })
