Hi, not sure if this is just me, an already known bug or what, but if anyone
can shed light on why this does what it does it would be greatly
appreciated, it seems to work as expected if you're dealing with Int32
variables rather than immediates.
public class Test
{
public void Tester( object o )
{
Console.WriteLine("not a byte");
}
public void Tester(byte o)
{
Console.WriteLine("is a byte");
}
};
Test t = new Test();
t.Tester((byte)0);
t.Tester((UInt32)0);
t.Tester((Int32)0); <--- reports "is a byte"
Regards,
Paul

It's not actually a bug, although I agree it looks that way at
first.(Int32)0 is still a constant expression (of type int), and so is
implicitly convertible to byte according to the spec.

Yeah, I guess that makes sense, albeit confusing if you see said code being
passed to a stream writer :) Thanks again.
Paul.

<spec section 13.1.7>
An implicit constant expression conversion permits the following
conversions:
· A constant-expression (§14.16) of type int can be converted to
type sbyte, byte, short, ushort, uint, or ulong, provided the value of
the constant-expression is within the range of the destination type.
</spec>
Never would have guessed. You learn something new every day.
