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);
