C#: Casting '0' to int

Question

I saw a code like this:

private readonly object[] m_Values = { (int)0, (int)0 };

What\'s the idea to cast 0 to int? Isn\'t it int by \'defa

Answer 1

I think it is pointless to have it like that, but the only place I think that can be useful is where the original coder wanted to prevent this value to be casted to other data type. Consider the example:

object[] m_Values = { (int)0, (int)0 };
Int16 item = (Int16) m_Values[0];

or

object[] m_Values = { (int)0, (int)0 };
Int64 item = (Int64)m_Values[0];

The above would result in

Specified cast is not valid.

but following would work:

object[] m_Values = { (int)0, (int)0 };
int item = (int)m_Values[0];
