C# Prevent Override
one up vote 14 down vote favorite 1 I'm having trouble overriding the method of a parent class in C#. The parent class is setup like so: public class Base { public Base(Game1 game) { this.game = game; } public virtual void Draw() { } } ...And the child class: public class Ext : Base { public Ext(Game1 game) : base(game) { } public override void Draw(SpriteBatch batch) { how can be restrict a method from being overridden } } I know I've successfully overridden a parent method in the past, and right now I'm probably overlooking something incredibly simple... what is it? EDIT: That was actually a typo: in the actual script, Ext does derive from Base. The problem still persists. Thanks for the quick answers, though. :) c# share|improve this question edited Jun 22 '11 at 20:47 asked Jun 22 '11 at 20:17 Jamie 3851618 You've not extended the base class public class Ext : Base –pero Jun 22 '11 at 20:18 Please show your exact code.

Some things to check, is everything public? That includes both the class and the method. Overload with different parameters? Are you sure that Base is the class you think it is? I.e. is there another class by the same name that it's actually referencing? Edit: To answer the question in your comment, you can't override a method with different

This requires you to be inheriting from a class that contains a virtual method that matches that declaration. In your case, the base class does not provide a virtual method that matches. You should be able to just remove the override keyword: public short ReadInt16() { byte[] byteBuffer = base.ReadBytes(2); return (short)((byteBuffer[0] << 8) | byteBuffer[1]); } share|improve this answer answered Oct 3 '13 at 15:51 Reed Copsey 394k377871110 Should he add the new keyword to hide the existing definition? –Harrison Oct 3 '13 at 15:56 @Harrison Not necessary. without new also it will shadow the base class method. new keyword is just to supress the warning –Sriram Sakthivel Oct 3 '13 at 16:06 @Harrison I suspect there is no existing definition - If there was, there'd probably be no reason to override it at all... –Reed Copsey Oct 3 '13 at 16:08 Assuming the base class is BinaryReader, ReadInt16 actually should be a virtual method. –Dan Bryant Oct 3 '13 at 16:08 @DanBryant In which case, there
