C#: How to show a newline within a MessageBox

Question

I often display messages using MessageBox.Show("This is my message");.
Sometimes I need a newline within a longer text. Usually I use a variant which put one string per line:
MessageBox.Show("Line1" + Environment.NewLine + "Line2" + Environment.NewLine + "Line3");
But I don't like the "overhead". So I found the following solution:
MessageBox.Show(string.Format("Line1{0}Line2{0}Line3", Environment.NewLine));
Is there a better solution with less overhead?

Answer 1

You have pretty much found both ways to do it. A third one would be with string interpolation (to avoid the "extra" string.Format call.

$"Line1 {Environment.NewLine} Line2 {Environment.NewLine} Line3"

The string.Format way is pretty much the example at the official format docs

I prefer interpolation as it avoids the extra function in my code, but really it all comes down to preference.

There really is no "overhead" in any of the options, as the operation is trivial and at the end of the day, you concatenate strings.
