Strange casting behaviour. Cannot cast object (int) to long

Question

I have the following code:

int intNumber1 = 100;
object intNumber2 = 100;
bool areNumberOfTheSameType = intNumber1.GetType() == intNumber2.GetType(); // TRUE         


        

Answer 1

You need to unbox to the same type that was boxed.

object intNumber2 = 100L;
// or value in the long type range
// object intNumber2 = 9223372036854775806;

long result = (long)intNumber2;
