Custom classes, ToString, and format strings

[Nathan Sokalski]

I have a custom class, and I would like to overload the ToString method so
that it accepts a format string like DateTime (and many other classes). I
believe this involves implementing the IFormattable interface, but the stuff
I found in the documentation showed it as accepting two parameters, the
format string and a System.IFormatProvider (I only want it to accept the
format string). Does anybody know of any good examples of doing this? I am
using VB.NET 2.0, but if an example in VB.NET is unavailable I would
appreciate an example in C# as well. Thanks.

I think you can just do

Public Overloads Function ToString(ByVal format As String) As String
' return a formatted string here
End Function
