C# Atrribute和反射的简单例子

Attribute 需要以Attribute 结尾, 并继承Attribute

namespace AttributeTest
{public class HeroAttribute : Attribute{}
}

namespace AttributeTest
{public class SkillAttribute : Attribute{}
}

namespace AttributeTest
{[Hero]public class Blademaster{[Skill]public void JiFengBu(){Console.WriteLine("疾风步");}[Skill]public void ZhiMingYiJi(){Console.WriteLine("致命一击");}}
}

using AttributeTest;
using System.Reflection;List<Type> heroTypes = new();
object selecthero;//所有英雄的类型
heroTypes = Assembly.GetExecutingAssembly().GetTypes().Where(t => t.GetCustomAttributes(typeof(HeroAttribute), false).Any()).ToList();//英雄的名字
var list = heroTypes.Select(t => t.Name).ToList();foreach (var item in list)
{Console.WriteLine(item);
}Console.WriteLine("==============");
foreach (var item in heroTypes)
{var t = Activator.CreateInstance(item);//创建对象var skillMethods = item.GetMethods().Where(m =>m.GetCustomAttributes(typeof(SkillAttribute), false).Any()).ToList();var methodsName = skillMethods.Select(m => m.Name).ToList();methodsName.ForEach(x => Console.WriteLine(x));
}

结果 :
