Question

以下是我的代码段。我需要的是我想在多个派生类中重用基类的成员。但是我得到了错误我在这里做错了什么？

public class A
{
    public int Num1;
    public int Num2;
    public int Num3;
    public int Num4;
}

public class B:A { // As it is inherting from base class A it should have access to base members
    //A ac = new A();
    Num1 = 1; // I'm getting error this fields does not exist in current context. How can i make re-use of class A members ?
    Num2 = 2;
    Num3 = 3;
    Num4 = 4;
}
public class C : A
{

    Num1 = 1;
    Num2 = 2;
    Num3 = 3;
    Num4 = 4;
}

Answer 1

这是无效的语法。

你的意思是

    public class C : A
    {
        public C()
       {
          Num1 = 1;
          Num2 = 2;
          Num3 = 3;
          Num4 = 4;
      }

}

Answer 2

如果您没有初始化它，则不应在A中声明变量。

但你可以使A抽象并使用属性：

public abstract class A
{
    public abstract int Num1 { get; }
}

public class B:A {
    public override int Num1 { get; } = 1;
}

无法重复使用基础成员
