c# - Inheritance and Overriding Methods/Properties -

If I have two squares, which gets from the other and I use the same method / property name in both

  Public class MyBase:  
  
 {Public Ink GetNumber () {Return 1; }} Public Sector MyDerived: MyBase {Public New Inc GetNumber () {Return 20; }} Myvard Avver = new Mirdiwide (); Int derivedVar = someVar.GetNumber (); // 20 mibbase baseware = (mybase) somewhere; Int baseVar = baseVar.GetNumber (); // 1  

My tendency would be to use override instead of new for derived class, but I get "no member found to override".

You must mark override before virtual Is required.
