大家好！

推荐答案

只是这一行并没有帮助我们把它放在上下文中来弄清楚你还在做什么。

所以上面的代码 - 你说的那样您可以在文件中写一次 - 也可能是相关的。



猜测，您正在尝试重用用于编写文件的文件流，这可能是问题的原因。如果流是从写入开放的，您可能无法通过单独的StreamReader重复读取它！

Just that line doesn't help us put it in context to work out what else you may be doing.
So the code above that line - you say that "you can write once in the file" - may be relevant as well.

At a guess, you are trying to reuse the file stream that you used for writing the file, and that is probably the cause of the problem. If the stream is open from writing, you probably can't reuse it for reading via a separate StreamReader!
