始终处置实现IDisposible接口的对象？ [英] Always dispose of an object that implements the IDisposible interface?
问题描述
如果一个对象实现了IDisposable接口（无论它是一个
框架对象还是一个用户对象），我应该总是原则上处理掉那个
对象吗？
If an object implements the IDisposable interface (regardless if its a
framework object or a user object), should I always dispose of that
object out of principle?

如果一个类实现了IDisposable，它几乎肯定有资源需要释放的资源 - 所以是的，你应该。一个''使用''块将确保
，你不要忘记这样做：
使用（DisposableThing x = new DisposableThing（））
{
// ...用x做点什么...
}

If a class implements IDisposable, it almost certainly has resources
that need freeing up - so yes, you should. A ''using'' block will ensure
that you don''t forget to do this:
using (DisposableThing x = new DisposableThing())
{
// ... do something with x ...
}

我不知道这是否总是真正。例如，sqlConnection可以关闭
。

I don''t know if this is always true. For example the sqlConnection can just
be closed.

今天，SqlConnection的Dispose方法唯一能做的就是确保
连接已关闭。明天，它可以做其他事情。如果你想要成为一个好公民，请打电话给Dispose并假装你不知道这是什么。
Today, the only thing that SqlConnection''s Dispose method does is make sure
the connection is closed. Tomorrow, it could do something else. If you
want to be a good citizen, call Dispose and pretend that you don''t know what
it does.
