LinQ C#防注入式攻击实例代码

注入式攻击是Web开放项目中开发人员的第一时间要考虑的问题，下面就我的开发实例分享给大家，有用的的话就点个赞吧。

 定義賬戶信息類
 public class UserInfors
 {
     public string EmployeeID { get; set; }
     public string UserName { get; set; }
     public string PassWord { get; set; }
         /// <summary>
         /// 重写Object类的ToString()方法
         /// </summary>
         /// <returns></returns>
         public override string ToString()
         {
              return string.Format("賬號：{0},姓名：{1},密碼：{2}",
                 this.EmployeeID,
                 this.UserName,
                 this.PassWord);
         }
 }

 使用LinQ進行用戶信息驗證
 DataTable Users;
         Users = ds.Tables[];
         //創建一個學生集合
         List<UserInfors> list = new List<UserInfors>();
         foreach (DataRow dr in Users.Rows)
         {
             list.Add(new UserInfors()
             {
                 EmployeeID = dr["EmployeeID"].ToString(),
                 UserName = dr["UserName"].ToString(),
                 PassWord =dr["PassWord"].ToString(),
             });
         }
         var result = from r in list
                      where r.EmployeeID == userid  && r.PassWord == password
                      select r;
         if (result.Count() > )
         {
             string name="";
             foreach (var ci in result)
             {
                name= ci.UserName;
             }

             Session.Add("UsersName", name);
             Session.Timeout = ;
             Response.Clear();
             Response.Write(name);
             Response.End();
         }
