如何在静态方法中获取类的反射

Question

如何在基类的静态方法中确定是那个派生类调用了这个静态方法？

例如：

class BaseClass
{
  public static void StaticMethod()
  {
    Type type = /*某种方法*/;
  }
}

class classA:BaseClass { }

class classB:BaseClass { }

如何在调用classA.StaticMethod()时，StaticMethod中type的值等于typeof(classA)，而在调用classB.StaticMethod()时，type的值等于typeof(classB)？

希望各位大神不吝赐教！！

建议你直接判断即可：

namespace CSharp
{
    class BaseClass
    {
        public static void StaticMethod(Type t)
        {
            if (typeof(BaseClass).IsAssignableFrom(t))
            {
                Console.WriteLine("是子类：" + t);
            }
            else
            {
                Console.WriteLine("不是子类……");
            }
        }
    }
 
    class classA : BaseClass { }
 
    class classB : BaseClass { }
 
    class Program
    {
       static void Main(string[] args)
        {
            classA.StaticMethod(typeof(classA));
        }
 
    }
}

基类是不会知道子类的信息的。

你可以在子类中重写这个方法，然后返回子类自己的信息。

多谢答复。

尽管把子类作为参数传递进去的做法比较难看，但是这貌似是唯一的解决方案了……
