                </asp>

DAL关键代码：

        public IEnumerable<M_Student> ReadStuByCollegeAndName(String collnum, String name)
        {
            return from s in dc.M_Student
                   where
                       (!String.IsNullOrEmpty(collnum) ? s.CollegeNum.Equals(collnum) : true) &&
                       (!string.IsNullOrEmpty(name) ? s.Name.Contains(name) : true)
                   select s;
        } 

aspx.cs关键代码

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using OnlineTest.Datalinq;

namespace OnlineTest.Manager

    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                Bind();
