String Format

Question

Hello

I have a string that can be 3 or 4 characters long, all I need to do is in case my string is 3 chars, add a single space in the beginning/end of my string, of course:

If string.Length = 3 Then string = " " + string
If string.Length = 3 Then string = string + " "

Just wonder if there's a string format syntax available to do the same? Thanks :)

Check the examples:

string s = "abc";

string result1 = string.Format( "Result 1 = '{0,4}'", s );
string result2 = string.Format( "Result 2 = '{0,-4}'", s );

string result3 = $"Result 3 = '{s,4}'";
string result4 = $"Result 4 = '{s,-4}'";

string result5 = s.PadLeft( 4 );
string result6 = s.PadRight( 4 );
