将文本框输出到文本文件不包含CR

Question

I've got a problem whereby I've created an application where the user enters text into various text boxes. They then click a button which outputs it all into a text log file in a specific format.

I create a string which I output to a file and that string is compiled from various pieces of text and the contents of various form elements.

When it outputs, each separate line which has been created as part of the string creation outputs with CR LF (\\r\\n) which is how I want it, but any text which was entered into a Rich Text Box outputs with only LF (\\n)

Code goes like:

string[] lines = {

     @"HEADER TEXT HERE",
     @"-----------------------------------------------",
     Text_Box.Text,
     Rich_Text_Box.Text,

........

Directory.CreateDirectory(@"\\basedirectory\" + project_name_tb.Text + @"\" + strDate);

System.IO.File.WriteAllLines(@"\\basedirectory\" + project_name_tb.Text + @"\" + strDate
+ @"\" + strDate + @"_" + project_name_tb.Text + @"_"
+ session_number_mtb.Text + @".txt", lines);

The rich text boxes are multiline.

How do I make the rich text box output CR LF?

Answer 1

您可以尝试用CRLF替换所有LF实例：

Rich_Text_Box.Text.Replace("\n", "\r\n")

Answer 2

I think this will solve your problem even it's safe if it's already \\r\\n it won't replace it.

    public string ReplaceRichTextBoxContent(string data)
    {
        return Regex.Replace(data, "(?<!\r)\n", "\r\n");
    }

use it like

string[] lines = {

 @"HEADER TEXT HERE",
 @"-----------------------------------------------",
 Text_Box.Text,
 ReplaceRichTextBoxContent(Rich_Text_Box.Text),
