C#: assign 0xFFFFFFFF to int

Question

I want to use HEX number to assign a value to an int:

int i = 0xFFFFFFFF; // effectively, set i to -1

Understandably, compiler complains. Q

Answer 1

The unchecked syntax seems a bit gar'ish (!) when compared to the various single-letter numerical suffixes available.

So I tried for a shellfish:

static public class IntExtMethods
{
    public static int ui(this uint a)
    {
        return unchecked((int)a);
    }
}

Then

int i = 0xFFFFFFFF.ui();

Because the lake has more fish.

Note: it's not a constant expression, so it can't be used to initialize an enum field for instance.
