使用StreamWriter不起作用\\ n（C＃）

Question

I have a problem with the C# Stream Writer. I use the following Code:

//Constructor
public EditorTXTFile
{
   FileStream f = File.Create(System.IO.Directory.GetCurrentDirectory() + "\\Output.txt");
   f.Close();
}

//Function AddText
public void AddLogFileText(string text)
{         
   string text = "l1\n\rl2\n\rl3\n\nl5";

   StreamWriter writer = new StreamWriter(System.IO.Directory.GetCurrentDirectory() + "\\Output.txt", true);
   writer.Write(text);         

   writer.Close();
}

When I open Output.txt it shows for \\n or \\ra █(which means not showable symbol) and the whole string is in one line... Later should the text hand over the function, so I can't write the text with .WriteLine because I don't know if the actual string is on the same line or in a new line.

What make I wrong?

Thanks for any help.

Answer 1

如果要手动执行，请使用Environment.NewLine作为行分隔符或"\\r\\n" 。

Answer 2

Line Separator(newLine) is \\r\\n not \\n\\r ,

change your text as :

       string text = "l1\r\nl2\r\nl3\r\nl5";

Answer 3

Try string text = @"l1\\n\\rl2\\n\\rl3\\n\\nl5"; . To prevent character stuffing.

Answer 4

This is binary format:

writer.Write(text); 

This is line sequential format:

writer.WriteLine(text); 

You have to use WriteLine format...

Answer 5

您可以像这样使用Environment.NewLine ：

streamWriter.Write(String.Concat(Enumerable.Repeat(Environment.NewLine, n).ToArray()));

Answer 6

i tried to write a class and seprate "\\n"s but i found rich text box!!

yeah! it works:

        RichTextBox rch = new RichTextBox();
        rch.Text = cmn;
        foreach (string l in rch.Lines)
            strw.WriteLine(l);
