推荐答案

只要这一切都在一个包裹使用块，然后你并不需要显式调用关闭。

So long as it's all wrapped up in a using block then you don't need to explicitly call Close.

使用块将确保该对象被处置，而关闭和的Dispose 方法是可以互换的的BinaryWriter 。 （在关闭方法只是调用的Dispose 幕后。）

The using block will ensure that the object is disposed, and the Close and Dispose methods are interchangeable on BinaryWriter. (The Close method just calls Dispose behind the scenes.)
