Passing enumeration, invalid argument?

Steffon Scott

I have a constructor which is taking a enumeration argument to determine the properties of the instantiated object:

public Support(playerClass playerClass)
{
if (playerClass == playerClass.Fighter)
{
name = "Soldier";
ambush = 0;
attack = 4;
copper = 0;
defend = 4;
range = 0;
food = 1;
mode = 0;
numattacks = 1;
regen = 0;
shield = 0;
swarm = 1;
train = 0;
firstStrike = false;
type = 2;
}
}

Now when I call this constructor and pass the argument I am getting an invalid argument error from VS.

case "soldier":
while (count >= 1)
{
units.Add(new Support(playerClass));
count--;
}
break;

Any ideas? From my understanding I AM passing the enumeration argument it should be expecting? Any help would be appreciated, thanks.

Edit: Also, here is the signature of the addUnit method:
public void addUnit(int amount, string type, playerClass playerClass)

Accepted answer
I suspect there is some confusion because you're (apparently) calling the constructor with a variable which has the same name as the enum itself (i.e. playerClass).

If you called it with an argument of playerClass.Fighter then it would probably work.

If I were you I'd change the name of the enum to PlayerClass (i.e. initial upper case letter) to avoid any confusion with variables or parameters which have the same name.

Awesome Vulpes, thanks again! Newbie mistake.

I'm sorry I should've put the signature of the calling method:

public void addUnit(int amount, string type, PlayerClass playerClass)
{
int count = amount;
switch (type)
{
case "soldier":
while (count >= 1)
{
units.Add(new Support(playerClass));
count--;
}
break;
