如果我写这样的东西,我不确定是否需要在使用的对象上调用 Flush()
:
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
}
它们总是自动刷新吗?using
语句何时刷新它们,何时不刷新(如果可能发生)?
Are they always automatically flushed? When does the using
statement flush them and when it doesn’t (if that can happen)?
一旦离开 using 块的作用域,流就会关闭并被释放.Close() 调用 Flush(),因此您不需要手动调用它.
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.
这篇关于如果使用“using"语句,是否需要在流或写入器上调用 Flush()?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
