从C＃中的基类，获得派生types？

假设我们有这两个类：

public class Derived : Base { public Derived(string s) : base(s) { } } public class Base { protected Base(string s) { } } 

如何从Base的构造函数中发现Derived是调用者？ 这就是我想到的：

 public class Derived : Base { public Derived(string s) : base(typeof(Derived), s) { } } public class Base { protected Base(Type type, string s) { } } 

有没有另外一种方式，不需要传递typeof(Derived) ，例如，从Base的构造函数中使用reflection的一些方法？

Answer 1

 using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Base b = new Base(); Derived1 d1 = new Derived1(); Derived2 d2 = new Derived2(); Base d3 = new Derived1(); Base d4 = new Derived2(); Console.ReadKey(true); } } class Base { public Base() { Console.WriteLine("Base Constructor. Calling type: {0}", this.GetType().Name); } } class Derived1 : Base { } class Derived2 : Base { } } 

该程序输出如下内容：

 Base Constructor: Calling type: Base Base Constructor: Calling type: Derived1 Base Constructor: Calling type: Derived2 Base Constructor: Calling type: Derived1 Base Constructor: Calling type: Derived2 

Answer 2

GetType()会给你你想要的。
