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;
}
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
}

If you have an enum such as
enum MyEnum
{
Foo,
Bar,
Baz,
}
and a value of that enum such as
MyEnum value = MyEnum.Foo;
then the best way to convert the value to an int is
int result = (int)value;
I would throw a third alternative into the mix in the form of an extension method on Enum
public static int ToInt(this Enum e)
{
return Convert.ToInt32(e);
}
enum SomeEnum
{
Val1 = 1,
Val2 = 2,
Val3 = 3,
}
int intVal = SomeEnum.ToInt();
