How to use String.Format in PowerShell?

Hah! (We’re back ;-) ) It’s as easy as that:

PS > [string] :: Format( "Hello {0} {1} :-)", "Daniel", "Walzenbach")
Hello Daniel Walzenbach :-)

Needless to say that other formatting – like Currency formatting – works as well

PS > [string] :: Format( "{0:C}", 1234567890)

Check out Formatting Types on the .NET Framework Developer's Guide or SteveX Compiled - String Formatting in C# (nice cheat sheet) for more examples.
