'；不实现接口成员'；System.ICloneable.Clone()'；

我在调用Icloneable接口时遇到一个小问题

我已经告诉该类我想使用这样的接口：

class UnitClass: ICloneable

并已加入克隆的功能

    public Object Clone()
    {
        return this.MemberwiseClone();
    }

然而，由于某种原因，程序告诉我，我还没有实现System.ICloneable.clone（），我甚至试着给函数起一个明确的名称，比如…

 public Object System.ICloneable.Clone()

但收效甚微，有人知道我做错了什么吗？
