在 c# 中实现接口时，如何从父 class 访问属性？

Question

If I have an interface

interface ISite {
    int g { get; set; }
}

and a base class

class Site {
    public int g = 1;
}

and a derived class that implements the interface and extends the class

class DSite : Site, ISite {
    // comaplains g is not defined
}

It complains that I did not implement the g property, but how do I make it take it from the parent class Site ?

Answer 1

Either make g in Site a property:

class Site
{
    public int g {get;set;} = 1;
} 

or explicitly implement the interface in DSite :

class DSite : Site, ISite
{
    int ISite.g
    {
        get { return g; }
        set { g = value; }
    }
}
