Explicit Casting C# with Example
If you know that a value is of a speciﬁc type, you can explicitly cast it to that type in order to use it in a context
where that type is needed.
object value = -1;
int number = (int) value;
If we tried passing value directly to Math.Abs(), we would get a compile-time exception because Math.Abs()
doesn't have an overload that takes an object as a parameter.
If value could not be cast to an int, then the second line in this example would throw an InvalidCastException
