Hah! (We’re back ;-) ) It’s as easy as that:
PS > [string] :: Format( "Hello {0} {1} :-)", "Daniel", "Walzenbach")
Hello Daniel Walzenbach :-)
Hello Daniel Walzenbach :-)
Needless to say that other formatting – like Currency formatting – works as well
PS > [string] :: Format( "{0:C}", 1234567890)
$1,234,567,890.00
$1,234,567,890.00
Check out Formatting Types on the .NET Framework Developer's Guide or SteveX Compiled - String Formatting in C#(nice cheat sheet) for more examples.
Cheers!
