动态调用WCF服务
本文转载:http://www.cnblogs.com/wiseant/archive/2010/07/29/1787599.html
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;
}
}
}
}
{
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" })
