C#  GetType()与Typeof()的区别

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：
