推荐答案

错误意味着什么 它说。您已完成一些文件处理并将文件保持打开状态，而不是关闭它。确保你调用'close'方法并使用块来表示隐藏idisposable的东西。

The error means what it says. You've done some file processing and left the file open, instead of closing it. Make sure you call 'close' methods and use using blocks for things that impliment idisposable.

你需要允许权限覆盖文件，或者你需要给它一个不同的名字你第二次保存它。

You'll need to allow permissions to overwrite the file or you need to give it a different name when you save it the second time.
