一，添加查询对象的实体类，数据访问类，业务逻辑类
实体类

数据访问类

namespace DAL
{
    public class StudentService
    {
        /// <summary>
        /// 根据班级名称查询学员信息
        /// </summary>
        /// <param name="className">班级名称</param>
        /// <returns>学员信息列表</returns>
        public List<Student> GetStudentByClass(string className)
        {
            string sql = "select StudentId, StudentName, Gender, Birthday, StudentIdNo, CardNo, PhoneNumber, StudentAddress, Students.ClassId from Students";
            sql += " inner join StudentClass on Students.ClassId=StudentClass.ClassId";//内连接
            sql += " where ClassName like '%{0}%'";//模糊查询
            sql = string.Format(sql, className);
            SqlDataReader objReader = SQLHelper.GetReader(sql);
            List<Student> list = new List<Student>();
            while (objReader.Read())
            {
                list.Add(new Student()
                {
                    StudentId = Convert.ToInt32(objReader["StudentId"]),
                    StudentName = objReader["StudentName"].ToString(),
                    Gender = objReader["Gender"].ToString(),
                    Birthday = Convert.ToDateTime(objReader["Birthday"])
                });
            }
            objReader.Close();
            return list;
        }
    }
}

业务逻辑类

二，添加对应的控制器和视图
控制器添加（都大同小异）

视图添加

获取当前用户名

@{
    string adminName = ((Models.SysAdmin)Session["CurrentAdmin"]).AdminName;

添加简单样式表

 <link href="../../Styles/stuManage.css" rel="stylesheet" />

三，显示结果
