Help with carriage return

[Keith Smith]

How come this code doesn't seem to work?

textBox1.Text=textBox1.Text.Replace("\r\n\r\n","\r\n");

I want to remove all blank lines in a textBox.

Actually, after another test it seems like it might be working. Would
someone just verify that the code structure is correct?

Try this

textBox1.Text=textBox1.Text.Replace(@"\r\n\r\n",@"\r\n");

No, that'd replace string literals, rather than escape sequences, and the
OP's code was fine.

I'd prefer the following though:

textBox1.Text=textBox1.Text.Replace(System.Environment.NewLine +
System.Environment.NewLine, System.Environment.NewLine);

Not as succinct, but more portable.

Is there a reason you are using System.Environment.NewLine instead of
Environment.NewLine?

Just to make it clear to him what namespace it's in...

Sorry, make it clear to you ;D

Serves me right for not checking the OP.
