不能使用Using来释放资源，比如下面的代码：
using (CalculatorClient client = new CalculatorClient())
{
...
} // <-- this line might throw
Console.WriteLine("Hope this code wasn't important, because it might not happen.");
推荐这个方式
//Create channel from factory
ChannelFactory channel =
new ChannelFactory<IService1>("bindingName");
IService1 client = channel.CreateChannel();
client.DoWork();
//Done with the service, let's close it.
try
{
if (client.State != System.ServiceModel.CommunicationState.Faulted)
{
client.Close();
}
}
catch (Exception ex)
{
client.Abort();
}
