Iterating from MinValue to MaxValue with overflow

Question

I have a simple loop which should look like this

for (sbyte i = sbyte.MinValue; i <= sbyte.MaxValue; i++)
{
    Console.WriteLine(i);
}

unfortunately sbyte.MaxValue +1 = sbyte.MinValue so this never meets the ending condition. My workaround was using int from -128 to 127 but is there also a native sbyte approach?

Answer 1

Not taking into consideration an obvious

output all except MaxValue, then output MaxValue

approach, I see one solution.
It works, but looks weird and throws OverflowException if checked :)

sbyte i = sbyte.MinValue;
do
{
    Console.WriteLine(i++);
} while (i != sbyte.MinValue);

Answer 2

You can try this :

for (sbyte i = sbyte.MinValue; i <= sbyte.MaxValue; i++)
{
    Console.WriteLine(i);
    if(i==sbyte.MaxValue)
     break;
}

Answer 3

You can use an int just for the condition and the sbyte inside.

int checkVal = sbyte.MinValue;
for (sbyte i = sbyte.MinValue; checkVal <= sbyte.MaxValue; i++, checkVal++)
{
    Console.WriteLine(i);
}
