C# - 获取类中属性的名称

用反射控制的,不过获取属性名称的方法,用方法形式获取的,不知道消耗大不大

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Qxun.Framework.Utility;
using System.Linq.Expressions;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("int类型=》" + typeof(int).Name);
            Console.WriteLine(GetPropertyName<GetProperty>(u=>u.Name1));
            //这个是拿所有名称的,不是那么灵活
            string name = typeof(GetProperty).GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance)[1].Name;
            Console.WriteLine(name);
            Console.ReadKey();
        }

        public static string GetPropertyName<T>(Expression<Func<T,string>> expr)
        {
            var name = ((MemberExpression)expr.Body).Member.Name;
            return name;
        }

    }

    public class GetProperty{
        public string Name1 { get; set; }
        public string Name2 { get; set; }
        public string Name3 { get; set; }
    }

}
