Using an array as argument for string.Format()

Question

When trying to use an array as an argument for the string.Format() method, I get the following error:

FormatException: Index (zero based)

Answer 1

Quick fix.

var place = new object[] { 1, 2, 3, 4 };

C# does not support co-variant array conversion from int[] to object[] therefor whole array is considered as object, hence this overload with a single parameter is called.
