Question

how to avoid overridable of class

Vulpes · Answer

You can prevent a class from being inherited from by declaring it with the sealed keyword. For example: public class A {...} public sealed class B : A // can't inherit from B {...} You can also use the sealed keyword to prevent virtual methods from being over-ridden further. For example: public class C { public virtual void M() {...} } public class D : C { sealed public override void M() // can't override M further {...} }
