新建和覆蓋的區別 - Difference between new and override

問題：

Wondering what the difference is between the following:想知道以下之間有什麼區別：

Case 1: Base Class案例 1：基類

public void DoIt();

Case 1: Inherited class案例一：繼承類

public new void DoIt();

Case 2: Base Class案例 2：基類

public virtual void DoIt();

Case 2: Inherited class案例二：繼承類

public override void DoIt();

Both case 1 and 2 appear to have the same effect based on the tests I have run.根據我運行的測試，案例 1 和案例 2 似乎具有相同的效果。 Is there a difference, or a preferred way?有什麼區別，還是首選方式？
