C#类型推测

代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 类型推测
{
    class Program
    {
        static void Main(string[] args)
        {
            var name = "Anne";      //var表示模糊类型，有可能是任何一种类型
            var age = 25;
            var isWriter = true;

            Type nameType = name.GetType();    //判断类型的方法
            Type ageType = age.GetType();
            Type isWriterType = isWriter.GetType();

            Console.WriteLine(nameType.ToString());   //输出
            Console.WriteLine(ageType.ToString());
            Console.WriteLine(isWriterType.ToString());

            Console.ReadKey();
        }
    }
}

结果：
