推荐答案

在没有看到代码的情况下很难猜测出问题所在，但是我相信您只是覆盖了文件，例如通过使用File.WriteAllLines.您应该使用例如来附加行函数File.AppendAllLines.

It is hard to guess what your problem is without seeing your code, but I believe you simply overwrite the file e.g. by using File.WriteAllLines. You should append your lines instead by using e.g. the function File.AppendAllLines.
