字符串中的换行符不适用于文本文件-解网

问：

我有一个将消息写入文本文件的功能。但是，当使用“Environment.NewLine”传递字符串时，它不会向文本文件写入新行。相反，它写的是“\r\n”。如何纠正这个问题？我尝试使用“\n”而不是“Environment.NewLine”。尽管如此，新生产线仍未到来。只有当将带有换行符的字符串传递给函数时，才会发生此问题。像变量 'message'

string message= "First "+Environment.NewLine+" message.";
LogTheDetails(message);

      public static void LogTheDetails(String message)
                {
          string path = AppDomain.CurrentDomain.BaseDirectory + "\\logs";       
          var directory = new DirectoryInfo(path);
             if (directory.Exists == false)
                        {
                            directory.Create();
                        }
        
                        string FilePath = path + "/" +  currentdate + ".txt";
                        if (!File.Exists(FilePath)) //FILE WRITING FIRST TIME
                        {
                            File.Create(FilePath).Dispose();
                            using (TextWriter tw = new StreamWriter(FilePath))
                            {
              tw.WriteLine("============================================================\n --Logs--");
                            }
                        }
                        else if (File.Exists(FilePath))//IF FILE ALREADY EXIST - APPEND LINES
                        {
                            string testString= "testString"+ Environment.NewLine+ "WithNewLine";
        File.AppendAllText(FilePath, "\n============================================================\n");
                            File.AppendAllText(FilePath, message);
                            File.AppendAllText(FilePath, testString);  
        File.AppendAllText(FilePath, "\n============================================================\n");
                        }
        }

输出

============================================================
--Logs--
============================================================
 First \r\n message.
testString
WithNewLine
============================================================

预期输出：

 ============================================================
    --Logs--
    ============================================================
    First
    message.
    testString
    WithNewLine
    ============================================================
