Default string formatter = "{0,22} {1}"; //what it mean?

Hi guys,

I got this piece of code from msdn, the thing that i don't understand is string formatter = "{0,22} {1}"; ---> what actually the {0,22} for?
        NumberFormatInfo provider = new NumberFormatInfo( );
        string formatter = "{0,22} {1}";

        int Int32A = -252645135;

        Console.WriteLine( formatter, "Default", "Format Provider" );
        Console.WriteLine( formatter, "-------", "---------------" );

        Console.WriteLine( formatter, Convert.ToString( Int32A ),
            Convert.ToString( Int32A, provider ) );

        print out:
               Default Format Provider
               ------- ---------------
             252645135 252645135

can somebody explain to me please. (since i'm quite new to c#)

Thanks in advance

.NET supports formatting strings. Each {x} token represents a value to be replaced and formatted. For example:

   String.Format("My name is {0}", "Peter")

results in "My name is Peter"

You can extend how each token behaves by putting formatting information after the the token indexer:

   String.Format("Today is {0,mm/DD/yyyy}", Date.Today)

results in "Today is 01/06/2006" (that formatting string may not be exactly correct, just to give you the idea)

In your example, I don't know off hand what 22 does. Look up formatting on MSDN and you'll find many pages about building formatting strings for dates, numbers, etc.
