如题。
可以为以后统一的实体类操作做准备。
以下代码.net5调试通过。
实体类Person:
using System; using System.Collections.Generic; using System.Text; using System.ComponentModel.DataAnnotations; namespace ConsoleApp1 { public class Person { [Key] [Display(Name = "姓名")] public string Xm { get; set; } [Display(Name = "年龄")] public int Nl { get; set; } public string Xb { get; set; } public Person(string _xm,int _nl,string _xb) { Xm = _xm; Nl = _nl; Xb = _xb; } } }
主类(把main改个insert啥的就接近能用了):
using System; using System.Linq; using System.ComponentModel.DataAnnotations; using System.Reflection; using System.Collections.Generic; namespace ConsoleApp1 { class Program { static void Main(string[] args) { Person p = new("张三", 20, "男"); PropertyInfo[] ps=getProperties(p); //获得主键和值 var keyword= getKeyandValue(p,ps); //如果需要获得剩下(除主键外)的内容,则执行这一句 //ps = ps.Where(p => p.ToString() != keyword.k.ToString()).ToArray(); //获得所有属性和值 var others = getAll(p,ps); //显示结果 Console.WriteLine(keyword.k.ToString()+","+ keyword.v); Console.WriteLine("---------------------"); foreach (var item in others) { Console.WriteLine(item.k + "," + item.v); } } static PropertyInfo[] getProperties(dynamic x) { return ((Type)(x.GetType())).GetProperties(); } static (PropertyInfo k,string v) getKeyandValue(dynamic x,PropertyInfo[] ps) { var p = ps.Where(p => p.GetCustomAttributes(typeof(KeyAttribute), false).Length > 0).FirstOrDefault(); return (p,p.GetValue(x).ToString()); } static IEnumerable<(string k,string v)> getAll(dynamic x,PropertyInfo[] ps) { foreach (var item in ps) { yield return (item.ToString(), item.GetValue(x).ToString()); } } } }
