类：
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace 简单人员管理系统1.App_Code{ public partial class Users { Data0425DataContext con = new Data0425DataContext(); public string NationName() { return con.Nation.Where(r => r.NationCode == this.Nation).First().NationName; } }}
