public class MyClass
{
public string s
public override boolean Equals(Object obj)
{
if(obj != null )
if (obj is string) // "Inappropriate Instanceof (C#)" warning issued here
// - expect instance check inside MyClass.Equals() to check MyClass (or a subclass of MyClass, if any)
return s.equals(obj);
return false;
}
}
In this example, the programmer should modify the Equals as follows:
public override boolean Equals(Object obj)
{
if(obj != null )
if (obj is MyClass)
return s.equals(((MyClass) obj).s);
return false;
}
Check if the is operator can be actually removed and that it is not the sign of an actual programming bug.
