Cannot access protected member 'object.MemberwiseClone()'

Question

I\'m trying to use .MemberwiseClone() on a custom class of mine, but it throws up this error:

Cannot access protected member \'object.Memberwise         


        

Answer 1

Within any class X, you can only call MemberwiseClone (or any other protected method) on an instance of X. (Or a class derived from X)

Since the Enemy class that you're trying to clone doesn't inherit the GameBase class that you're trying to clone it in, you're getting this error.

To fix this, add a public Clone method to Enemy, like this:

class Enemy : ICloneable {
    //...
    public Enemy Clone() { return (Enemy)this.MemberwiseClone(); }
    object ICloneable.Clone() { return Clone(); }
}
