GetType()与Typeof()区别

GetType(）返回的是对象的类名；

案例1：

int i = 5;

Console.WriteLine(i.GetType());//System.Int32
var x = 127.25m;

Console.WriteLine(x.GetType());//System.Decimal

案例2：

namespace _2011._12._15

{

    class Program

    {

        static void Main(string[] args)

        {

            Test testone = new Test();

            string s = testone.GetType().ToString();

            Console.WriteLine(s);//_2011._12._15.Test  命名空间的Test类
        }

    }

    class Test

    {     

    }

}

Typeof()返回的是类名的对象，也可以返回类名，也可以返回特定类内部的方法和字段

namespace _2011._12._15

{

    class Program

    {

        static void Main(string[] args)

        {

            Test testone = new Test();

            string s = testone.GetType().ToString();

            Console.WriteLine("GetType():");

            Console.WriteLine(s);//_2011._12._15.Test  命名空间的Test类


            Type type = typeof(Test);

            Console.WriteLine("Typeof():");

            Console.WriteLine(type);//_2011._12._15.Test  命名空间的Test类
            Console.WriteLine();



           MethodInfo[] methodinfo = type.GetMethods();



           Console.WriteLine(methodinfo.GetType());//System.Reflection.MethodInfo[]
            foreach (var i in methodinfo)

            {

                Console.WriteLine(i);//输出Test类的所有方法及继承Object的实例方法
            }

            Console.WriteLine();

            Console.WriteLine();

            Console.WriteLine();

            Console.WriteLine();

            MemberInfo[] memberinfo = type.GetMembers();

            Console.WriteLine(memberinfo.GetType());

            foreach(var i in memberinfo)

            {

                Console.WriteLine(i);//输出Test类字段和System.type类型
            }

        }





    }

class Test

    {



        private int age;

        public string name;

        public void speaking()

        {

            Console.WriteLine("Welcome to cnblog!");

        }





        public void writing()

        {

            Console.WriteLine("Please writing something!");

        }

    }

}

运行结果：

GetType():

_2011._12._15.Test

Typeof():

_2011._12._15.Test



System.Reflection.MethodInfo[]

Void speaking()

Void writing()

System.Type GetType()

System.String ToString()

Boolean Equals(System.Object)

Int32 GetHashCode()









System.Reflection.MemberInfo[]

Void speaking()

Void writing()

System.Type GetType()

System.String ToString()

Boolean Equals(System.Object)

Int32 GetHashCode()

Void .ctor()

System.String name
