Index (zero based) must be greater than or equal to zero

Question

Hey I keep getting an error:

Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

Answer 1

This can also happen when trying to throw an ArgumentException where you inadvertently call the ArgumentException constructor overload

public static void Dostuff(Foo bar)
{

   // this works
   throw new ArgumentException(String.Format("Could not find {0}", bar.SomeStringProperty));

   //this gives the error
   throw new ArgumentException(String.Format("Could not find {0}"), bar.SomeStringProperty);

}
