Hi Daniel,
Thank you for posting in the community!
Based on my understanding, you want to know the difference between *use* or
*not use* base keyword to invoke method in C#.
=============== =============== =============== ============
Actually, if you explicit use base keyword, it means that you want to
invoke the BASE class's method. While "not use" the base keyword, you just
invoke your class's method, which may inherited from your BASE class.
So, the difference may expose using polymorphism, below is the sample code:
class A
{
public virtual void F() { Console.WriteLi ne("A.F"); }
}
class B: A
{
static void Main()
{
B b=new C();
b.test();
}
public void test()
{
base.F();
F();
}
public override void F() { Console.WriteLi ne("B.F"); }
}
class C: B
{
public override void F() { Console.WriteLi ne("C.F"); }
}
The output will generate:
A.F
C.F
So I think you have seen the difference, *not use* base keyword will lead
to the polymorphism, while *use* it will lead to explicit invoke base class
method.
