c#从类的实例中获取静态属性的值

Question

How do I get the value of a static property from an instance of a class? see example below...

abstract class A {
   public static double Foo {get; protected set;}
}

class B : A {
   static B(){
      Foo = 1;
   }
}

class C : A {
   static C(){
      Food = 2;
   }
}

class Test {
   A test = new B();

   //How do I get test.Foo ??
}

Answer 1

Static members (fields, properties, methods, etc.) are accessed via class name.

var x = A.Foo;

I think you are getting statics wrong.

Did you mean something like this?

abstract class A {
   public double Foo {get; protected set;}
}

class B : A {
   public B(){
      Foo = 1;
   }
}

class C : A {
   public C(){
      Foo = 2;
   }
}

class Test {
   A test = new B();
   var foo = test.Foo;
}
