        {


            Response.Redirect("information1.aspx");

       }

    {
       bool boolReturnValue = false;  what this line do?

            dt = new DataTable();
            SqlConnection con = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\omar\Documents\Visual Studio 2005\WebSites\Project1\App_Data\Database.mdf;Integrated Security=True;User Instance=True");
            string chkUser = "Select * FROM [User] where Email='" + UserName + "' AND Password='" + Password + "'";
            dt = dbClass.ConnectDataBaseReturnDT(chkUser);
            if (dt.Rows.Count > 0)
            {
                boolReturnValue = true; what this line do?
                Session["Id"] = dt.Rows[0]["Id"].ToString();
               string que = "UPDATE [User] SET LastLogin = GETDATE() where Id=" + Session["Id"].ToString();
              //  DateTime registerdate = (DateTime)dt.Rows[0]["RegisterDate"];
               // string que1 = "UPDATE [User] SET RegisterDate = GETDATE() where Id=" + Session["UserId"].ToString();
               dbClass.ConnectDataBaseToInsert(que);
                //dbClass.ConnectDataBaseToInsert(que1);

推荐答案

我认为您应该读一两本书.您的问题的答案非常明显.如果您的角色是公司中的.Net开发人员，请告诉他们您不是.如果您是学生，请尝试以下操作:

在代码的以下行上放置一个断点:

I think you should read a book or two. Answers to your questions are quite evident. If your role is of a .Net developer in company, tell them you are not one. If you are a student, try following:

Put a break point at the following line in your code:

bool Authenticated = false;

单步执行并进入代码(使用F11进行调试，而不使用F10).这应该可以帮助您了解其工作原理.

希望这会有所帮助.

Step through and into the code (use F11 to debug and not F10). This should help you understand how this works.

Hope this helps.
