I'm developing a program that I'm using a string(
generatedCode) that contains some
\n to enter a new-line at the textBox that I'm using it(
textBox1.Text = generatedCode), but when I'm running the program, instead of breaking that line I'm seeing a square.
Remember that I've set the
Multiline value of the textBox to
Replace \n with \r\n - that's how Windows controls represent newlines (but see note at bottom):
textBox1.Text = generatedCode.Replace("\n", "\r\n");
textBox1.Text = generatedCode.Replace("\n", Environment.NewLine);
Note: As discussed in comments, you may want to use
Environment.NewLine. It's unclear though - it's not well-defined what line separator Windows Forms controls should use when they're not running on Windows. Should they use the platform default, or the Windows one (as it's a port of a Windows GUI control)? One of the examples in MSDN does use
Environment.NewLine, but I've seen horribly wrong examples in MSDN before now, and the documentation just doesn't state which is should be.
In an ideal world, we'd just have one line separator - and even in a second best world, every situation would clearly define which line separator it was expecting...
How To Use \n In a TextBox, You want to either prefix your string with @ or you can use a double slash before each n (\n). Both of these are ways of escaping the \ so that it Output: (In Message box only) I am coming from Forget Code In Message box you can see the newline but not in the text box.

TextBox1.Text = str.Replace("\r\n", "\n").Replace("\n", Environment.NewLine);

- Basically the same thing, but it's probably safer to use Environment.NewLine instead of \r\n, I think.
- Hmm, question - ought "\r\n" be System.Environment.NewLine? I appreciate that they're the same (ish), its more of a sort of coding standardy type question
- Given that ".NET" does not imply "Windows," I would strongly concur with using
- That entirely depends on what other platforms decide to do for Windows Forms controls. Given that they're Windows Forms controls, they may well copy the use of "\r\n". To be honest, it feels like Mono is stuck between a rock and a hard place on this one. I would definitely use
Environment.NewLinefor writing a text file for example, but I'm not so sure for WinForms GUIs. Caveat: I don't actually know what Mono does with this on Linux.
- Good point! just be sure do textBox1.Text = generatedCode.Replace("\r\n", "\n"); to get any existing then do the textBox1.Text = generatedCode.Replace("\n", "\r\n"); Winform still rocks!
