如何使用虚方法，重写，接口那实现不一样的结果

基础参数

interface，abstract，virtual，override

然后实现了这样的效果

 

 同一个方法，调用不同的实现类，那实现不一样的结果

具体代码

public interface IStatsBase{string UserSpeak(string content);string UserHandel(string content);}public interface IUserStatsBase{string UserLook(string content);}public abstract class UserStatsBase : IUserStatsBase, IStatsBase{protected abstract string Name { get; }public virtual string UserHandel(string content){return $"{Name}做：{content}";}public virtual string UserSpeak(string content){return $"{Name}说：{content}";}public virtual string UserLook(string content){return $"{Name}看：{content}";}}public class XiaoHongStats : UserStatsBase{protected override string Name => "小红";public override string UserHandel(string content){StringBuilder str = new StringBuilder();str.AppendLine(UserSpeak("我那去扫地"));str.AppendLine("去扫地了");return str.ToString();}}public class ZhangSangStats : UserStatsBase{protected override string Name => "张三";public override string UserSpeak(string content){return $"{Name}说：{content}，并且带着大家去做";}}
