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。

16                 Type type = typeof(T);
17                 MethodInfo mi = type.GetMethod(pMethodName);
18                 return mi.Invoke(instance, pParams);
19             }
20             catch (TimeoutException)
21             {
22                 (instance as ICommunicationObject).Abort();
23                 throw;
24             }
25             catch (CommunicationException)
26             {
27                 (instance as ICommunicationObject).Abort();
28                 throw;
29             }
30             catch (Exception vErr)
31             {
32                 (instance as ICommunicationObject).Abort();
33                 throw;
34             }
35         }
36     }
37 }

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" })
