c# - Enum to int best practice

I can't select between two methods of converting. What is the best practice by converting from enum to int

1:

public static int EnumToInt(Enum enumValue)
{
    return Convert.ToInt32(enumValue);
}

2:

public static int EnumToInt(Enum enumValue)
{
    return (int)(ValueType)enumValue;
}

Answer

In addition to @dtb

You can specify the int (or flag) of your enum by supplying it after the equals sign.

enum MyEnum
{
    Foo = 0,
    Bar = 100,
    Baz = 9999
}

Cheers
