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.
