New lines (\n) in Text boxes

[Guest]

In the C++ version of MessageBox() I could embed \n to get a new line. In the C# version of this the \n shows up as \n.

How can I tell the message box (or a textBox on a custom form) to recognize the \n as a newline character and display whatever comes after the \n on a new line

This is real basic, but I'm not able to get it to work

Use Environment.Newline, like:

MessageBox.Show("Line 1" + Environment.Newline + "Line 2");

Hope this helps

Inside a string literal, you can still use "\r\n". You can use
'Environment.NewLine' instead of the combination:

\\\
MessageBox.Show(
"Hello" + Environment.NewLine +
"World\r\n"
"!"
);
///

Errata:

"World\r\n"
"!"

Add a " +" at the end of the first line ;-).

This works fine for me
MessageBox.Show("Test Line 1\nTest Line 2")

Are you doing this instead
MessageBox.Show(@"Test Line 1\nTest Line 2")

The second method will give you the behavior you describe.

I have more information. These messages "hello\nthere" are coming
from a resource (resx) file. When the message is read in from the
resource file it adds an additional backslash, thus yielding
"hello\\nthere", so I guess the more appropriate question is, how can I
read this resource and not get the extra backslash from the .resx file?

Right -- that won't work as expected because the "\n" is converted to
the according character at runtime when using "\n" iside a string
literal.

So how do I remove or change the @ string type, either with ResourceManager or programmatically
