                FileStream ostrm;
                StreamWriter writer;
                TextWriter oldOut = Console.Out;
                try
                {
                    ostrm = new FileStream("C:/Users/Joanne/Desktop/WriteLines35.txt", FileMode.Append | FileMode.OpenOrCreate , FileAccess.Write);
                    writer = new StreamWriter(ostrm);
                }
                catch (Exception e)
                {

                    Console.WriteLine(e.Message);

                    ostrm.Close();
                    Console.WriteLine("Done");
                }

推荐答案

说，不是第二个Console.SetOut （）设置为 oldOut 而不是
作家？

您的最终"完成"输出也将写入文件，但流现已关闭。

Your final "Done" output is to be written to the file as well, but the stream is now closed.
