动态调用WCF服务[转]

原文地址：http://blog.csdn.net/castlooo/archive/2010/05/06/5562619.aspx

 

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" })
