代码如下:

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Reflection;

namespace CustomAttributeConApp
{
    class Program
    {
        static void Main(string[] args)
        {
            MemberInfo info = typeof(MyClass);
            CodeProgramAttribute attr = (CodeProgramAttribute)Attribute.GetCustomAttribute(info, typeof(CodeProgramAttribute));
            if (attr != null)
            {
                Console.WriteLine("类\"MyClass\"应用\"CodeProgramAttribute\"属性,参数如下:\n");
                Console.WriteLine("reviewer:" + attr.Reviewer);
                Console.WriteLine("date:" + attr.Date.ToString());
                Console.WriteLine("comment:" + attr.Comment);
            }
            else
            {
                Console.WriteLine("类\"MyClass\"没有应用\"CodeProgramAttribute\"属性");
            }
            Console.ReadKey();
        }
    }

    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
    public class CodeProgramAttribute : Attribute
    {
        private string reviewer;    //代码检查人
        private CheckTime date;        //日期
        private string comment;     //评价

        public CodeProgramAttribute(string reviewer, CheckTime date)
        {
            this.reviewer = reviewer;
            this.date = date;
        }

        public string Reviewer
        {
            get
            {
                return reviewer;
            }
        }

        public CheckTime Date
        {
            get
            {
                return date;
            }
        }

        public string Comment
        {
            get
            {
                return comment;
            }
            set
            {
                comment = value;
            }
        }
    }

    public enum CheckTime
    {
        am = 1,
        pm = 2
    }


    [CodeProgram("张三", CheckTime.pm, Comment = "检查情况比较好!")]
    public class MyClass
    {
        public static void Do()
        {
            Console.WriteLine("做完了一件事情!");
        }
    }
}
