C# type rebinding, very ngerful-优快云博客

本文介绍了一个C#程序示例，展示了如何在C#中模拟泛型类型重绑定的功能，这是C++程序中常见的特性。通过具体的代码实现，解释了泛型类型重绑定的基本原理。

C# type rebinding, a program demonstrating what I can figure out about simulating
generic type rebinding in C# (which is so common in C++ programs), it may look
stupid, but it really works as intended.

using System; class BaseG { public class ReboundType<_T> { public virtual _T T {get; set;} public virtual void Do() {} } public virtual ReboundType<_T> Rebind<_T>() { return new ReboundType<_T>(); } } class G : BaseG { public new class ReboundType<_T> : BaseG.ReboundType<_T> { _T t; public override _T T { get {return t;} set{t = value;} } public override void Do() { Console.WriteLine("G.ReboundType<>.t = {0}", t); } } public override BaseG.ReboundType<_T> Rebind<_T>() { return new ReboundType<_T>(); } } class User<_G> where _G : BaseG, new() { BaseG.ReboundType<String> gs = new _G().Rebind<String>(); public void Test() { gs.T = "abc"; gs.Do(); } } class App { static void Main(String[] args) { User<G> ug = new User<G>(); ug.Test(); } }
