unreachable code

hey all.

i got a problem here, im getting a cs0162 unreachable code

Using NET Framework 2.0.50727

here is the block its coming from,i commented on the line that is unreachable

Code:

---

        public void LabelToAffix(Mobile to, int number, AffixType type, string affix, string args)
        {
            string message = StringList.CombineArguments(number, args);

            MessageType label = MessageType.Label;
            if ((type & AffixType.Append) != 0)
                message += affix; //unreachable
            else
                message = affix + message;
            if ((type & AffixType.System) != 0)
                label = MessageType.System;

            to.Send(new AsciiMessage(m_Serial, m_ItemID, label, 0x3B2, 3, "", message));

---

What does AffixType.Append return?

It would appear that the compiler thinks it always returns 0.

Is that the case?

If the AffixType is an enum, mark it with the [Flags] attribute and be sure the values are 2's compliment.

Code:

---

[Flags]
public enum AffixType
{
  Append = 1,
  System = 2,
  Network = 4
}

I am not sure if this will resolve your problem but since "&" operator works on "integral types" try casting your variables into one of those, i.e. try:

Code:

---

if (((int) type & (int) AffixType.Append) != 0)

---

instead of the if statement that you had before.

Let me know if it worked.

You don't need to cast an enum (if that's what this is) to use bitwise operators on it. You don't eevn need to use the Flags attribute, you just need to make sure that each value is a power of 2.

I think AffixType.Append = 0 (it could be if it is the first element of enum and you don't specify values like Arjay sugest), than anything & 0 is always 0, which cannot differ from zero, so the condition cannot be satisfied in any way.
