Newline and multiline textbox in C#

[Kimmo Laine]

Hi,

i know this is a stupid question, but... how can i add text to separate
lines when i have a multiline textbox?

// This don´t work
myTextBox.Text = "Hello\nWorld!";

Try:

myTextBox.Text = "Hello\r\nWorld!";

Kimmo,

A linebreak in Win/DOS made up of two characters (carriage return and
line feed) so you will need to pass \r\n or use the Environment.NewLine
contstant instead.

LC,

Please note that this would require two explicit type casts and would
be slower than using the escape characters or NewLine constand.

Hi,

Console.WriteLine("Hello" + (char)13 + (char)10 + "world");

Andreas:

Please note in my example code that (char)13 is a constant expression:

const char LF = (char)13; //is valid

.... and it is fully evaluated at compile-time, even if the expression is a
sub-expression of a larger expression that contains non-constant constructs.

C# Reference. 14.15

LC,

You are ofcourse correct on this =)

Yes, the char itself is a constant. However, the concatenation is still
required at runtime, so it's still slower than writing

Console.WriteLine ("Hello\r\nWorld"); or even

Console.WriteLine ("Hello"+Constants.CRLF+"World");

where Constants is defined as (say)

public class Constants
{
public const string CRLF = "\r\n";
}

Using Environment.Newline *doesn't* remove the concatenation, of
course, because it's not a compile-time constant.
