请教WCF客户端代理类的资源释放问题

[iamseakingii]

请教一下 ChannelFactory<T>.CreateChannel() 创建出来的怎么能安全,方便的释放资源?
目前我是做了一个封装,然后:

using(var client = new Client<IMyService>())
{
//调用

}

这样来释放,但总感觉使用 using 很累也不好看.请问 ChannelFactory<T>.CreateChannel() 创建出来的需要保证释放一定要释放掉吗?有没有更方便有效的办法?

下面是Client代理类的大致方法:

public class Client<T> : IDisposable
{
    private readonly T client;   

    public Client()
    {      
        var factory = new ChannelFactory<T>();
        client = factory.CreateChannel();
    }    


    public void Dispose()
    {
        if (disposed) return;

        try
        {
            var c = client as ICommunicationObject;
            if (c != null)
            {
               CloseConnection(c);
            }

           
        }
        catch (Exception ex)
        {
            Debug.WriteLine("Client dispose error:" + ex.Message);
        }

        disposed = true;
        
    }

	
    public static void CloseConnection(ICommunicationObject myServiceClient)
    {
        if (myServiceClient.State != CommunicationState.Opened)
        {
            return;
        }
        try
        {
            myServiceClient.Close();
        }
        catch (CommunicationException ex)
        {
           
            myServiceClient.Abort();
        }
        catch (TimeoutException ex)
        {            
            myServiceClient.Abort();
        }
        catch (Exception ex)
        {            
            myServiceClient.Abort();
            throw;
        }
    }


}

既然是IDisposable，那么就要显式地调用Dispose()去释放资源。using会自动调用这个函数，我觉得比自己手动调用好看多了

很漂亮啊，哪不好看了？
