如果使用"using"语句，是否需要在流或编写器上调用Flush()? [英] Do you need to call Flush() on a stream or writer if you are using the “using” statement?

问题描述

我不确定是否需要在使用的对象上调用Flush()，例如我写这样的东西:

I am not sure whether I need to call Flush() on the used objects if I write something like this:

using (FileStream...)
using (CryptoStream...)
using (BinaryWriter...)
{
    // do something
}

它们是否总是自动冲洗? using语句何时刷新它们，什么时候不刷新(如果可能的话)?

Are they always automatically flushed? When does the using statement flush them and when it doesn’t (if that can happen)?

推荐答案

一旦您离开了using块的作用域，就将关闭流并对其进行处置. Close()调用Flush()，因此您无需手动调用它.

As soon as you leave the using block’s scope, the stream is closed and disposed. The Close() calls the Flush(), so you should not need to call it manually.
