How cool is this?! OK, maybe I get a little overexcited about new features and specifically new features that work with intellisense. In .NET v2.0, if I create a generic class with a base type constraint, any instance of the generic type parameter allows me to see use the base class's (that is defined as the constraint) properties and methods The base class constraint means that the type argument must be or derive from the specified base class. So, if I create a Shape class that has a Draw method, I can call t.Draw() in my generic class...
abstract
class Shape
{
abstract void Draw();
}
class
Circle : Shape
{
private
override void
Draw() {
throw new
NotImplementedException();
}
}
class
SomeGenericClass<T>
where T : Shape {
T t =
null;
public
void SomeMethod() {
//Can call draw on t due to the constraint
t.Draw();
}
}
