Enums

[Guest]

Hi,

If I have this enumeration:

public enum SampleEnum
{
First=1,
Second=2,
Third=3
}

and I have a variable of type SampleEnum, how do I get its corresponding
number?
I tried this:

SampleEnum a=SampleEnum.Second;
int i=a.ConvertToInt16(a); // i=2

and it works, but I am not sure if it is the right way to do it.

Thanks

This should be enough:

int i = (int) SampleEnum.Second;

Enums inherit from one of the simple integer types (byte, int16, int32, int64...).
If you do not specify which one it will inherit from int32. Thus, you can
do a direct cast to Int32 or any other integer type. So you could just as
easily do: int i = (int)a;
