我对清理 ServiceHost 的最佳方法有些困惑。由于 Visual Studio 代码分析器的 CA1001 警告建议我为我的类实现 IDisposable 接口(interface),因此我意识到了我的代码中的问题。
我已阅读有关 IDisposable 的讨论并熟悉典型用例,但发现自己在这种情况下感到困惑。确保 ServiceHost 被处理并可能满足 CA1001 的正确方法是什么?谢谢。
我的代码如下所示:
public class MyClass
{
private ServiceHost host = null;
public void StartListening(...)
{
// make sure we are not already listening for connections
if (host != null && host.State != CommunicationState.Closed)
StopListening();
// create service host instance
host = new ServiceHostWithData(typeof(ServiceHandler), address);
// do a bunch of configuration stuff on the host
host.Open();
}
public void StopListening()
{
// if we are not closed
if ((host != null) && (host.State != CommunicationState.Closed))
{
host.Close();
host = null;
}
else // we are null or closed
{
host = null; // if it isn't null, and it is already closed, then we set it to null
}
}
}
最佳答案
你的类应该实现 IDisposable 。基于该 MSDN 页面的示例:
public class MyClass : IDisposable
{
private bool disposed = false;
private ServiceHost host = null;
public void StartListening(...)
{
// ....
}
public void StopListening()
{
// ...
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
if(!this.disposed)
{
if(disposing)
{
this.StopListening();
}
disposed = true;
}
}
~MyClass()
{
Dispose(false);
}
}
