推荐答案

也许核心问题是底层流是关闭的.如果您在流的顶部创建一个新流，然后将其关闭，则默认情况下将关闭基础流.

maybe the core problem is, that the underlying stream is closed. If you create a new stream on top of a stream and then close it, then the underlying stream is closed by default.

因此，您有一个using块，其中有一个BinaryWriter(cout)，并且在处置BInaryWriter时，流已关闭，因此您无法向其写入更多数据.

So you have a using block where you have a BinaryWriter(cout) and when the BInaryWriter is disposed, the stream is closed so you cannot write more data to it.

但是您可以高兴-BinaryWriter也有一个接受3个参数的构造函数，其中最后一个参数负责此行为:

But you can be happy - BinaryWriter also has an constructur which takes 3 arguments where the last argument is taking care of this behaviour:

也许您在其他流中遇到了类似的问题-不确定如何进一步使用该代码.但是，当处置cout时，基础流也将被关闭.

Maybe you run into similar issues with the other streams - not sure how the code is used further. But when cout is disposed, the underlying stream will be closed, too.
