 简化版

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace GetValue{    class Program    {        static void Main(string[] args)        {            Person ps = new Person();            ps.Name = "CTZ";            ps.Age = 21;            Console.WriteLine(ps.GetValue("Name"));            Console.WriteLine(ps.GetValue("Age"));        }    }    class Person    {        public string Name        { get; set; }        public int Age        { get; set; }        public object GetValue(string propertyName)        {            return this.GetType().GetProperty(propertyName).GetValue(this, null);        }    }}

 实质语句只有一句：

this.GetType().GetProperty(propertyName).GetValue(this, null);
