Posted 2020-09-15 81192

通过C#中的type类获取类中的字段、属性、方法等相关信息。

    class newClass
    {
        public string Id01;
        public string Id02;
        public string Id03;

        public string Name01 { get; set; }
        public string Name02 { get; set; }
        public string Name03 { get; set; }

        public void Method01()
        {
        }
        public void Method02()
        {
        }
        public void Method03()
        {
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            newClass testClass = new ReflectionTest01.newClass();
            testClass.Id01 = "01";
            testClass.Id02 = "02";
            testClass.Id03 = "03";
            testClass.Name01 = "name01";
            testClass.Name02 = "name02";
            testClass.Name03 = "name03";

            Type type = testClass.GetType();
             //获取基本属性
            //获取类名
            Console.WriteLine(type.Name);
            //获取命名空间
            Console.WriteLine(type.Namespace);
            //获取命名空间
            Console.WriteLine(type.Assembly);
            //获取public的字段
            FieldInfo[] fields = type.GetFields();
            foreach(FieldInfo info in fields)
            {
                Console.Write(info.Name+" ");
                Console.Write(info.GetValue(testClass)+ " ");
            }
            Console.WriteLine();
            //获取属性
            PropertyInfo[] props = type.GetProperties();
            foreach (PropertyInfo info in props)
            {
                Console.Write(info.Name + " ");
                Console.Write(info.GetValue(testClass)+ " ");//获取对应的值
            }
            Console.WriteLine();
            //获取方法
            
            MethodInfo[] methods = type.GetMethods();
            foreach (MethodInfo info in methods)
            {
                Console.Write(info.Name + " ");
            }
            Console.WriteLine();




            Console.ReadKey();
        }
    }

可以通过EventInfo[] events=type.GetEvents（）；获取类的事件。
