如何将会话存储到泛型中 [英] How to store session into generics

问题描述

protected void Btn_Next_Click(object sender, EventArgs e)
        {
            bool flag = false;
            pobj.InsertProblem();
            int problemid = pobj.Maxid();
            List<resourcedto> objResourceList = new List<resourcedto>();
            foreach (GridViewRow rw in GridView1.Rows)
            {
                CheckBox chk = (CheckBox)rw.FindControl("CheckBox1");
                TextBox txt = (TextBox)rw.FindControl("TxtProfit");
                if ((chk.Checked == true) && (txt.Text != ""))
                {
                    ResourceDTO objResourceDTO = new ResourceDTO();
                    objResourceDTO.ItemName = chk.Text;
                    objResourceDTO.Profit = Convert.ToInt32(txt.Text);
                    objResourceDTO.ItemId = Convert.ToInt32(GridView1.DataKeys[rw.RowIndex].Value);
                    objResourceDTO.ProblemId = problemid;
                    objResourceList.Add(objResourceDTO);
                    //string sql_prblm = string.Format("insert into ProblemProduct(ProblemId,ItemId,Profit)values('{0}','{1}','{2}')", problemid, itemid, profit);
                    //pobj.InsertProblemproduct(sql_prblm);    
                    flag = true;
                }
                Session["ResourceDTOList"] = objResourceList;
            }
            if (flag)
            {
                Response.Redirect("ProblemResource.aspx");
            }
            else
            {
                ClientScript.RegisterStartupScript(this.GetType(), "key", "alert('Select something first')", true);
            }
        }

我在单击下一步按钮时使用了泛型，它应该移至该页面中的问题资源页面，我必须将该会话分配给列表.请帮忙

I have used generics on click of next button it should move to problem resource page in that page i have to assign that session to list. please help out

推荐答案

不确定我是否会像这样存储它，但是，我认为您正在学习该会话的工作方式(我认为我在那个方向).您读过文章还是只是复制了我给您的一小段代码?

在另一页中，

List< resourcedto> objResourceList =(List< resourcedto>)Session ["ResourceDTOList"];

这段代码有很多错误，但是它可以正常工作，而且看来您现在正在迈出第一步，所以我不想在细节上过多介绍您.我假设没有人正在使用此代码，我无法想象有人不知道会话是什么，就会付钱编写Web代码.

Not sure I would have stored it like this, but, I think you''re learning how the session works ( I think I pointed you in that direction ). Did you read articles or just copy the one bit of code I gave you ?

In the other page,

List<resourcedto>objResourceList = (List<resourcedto>)Session["ResourceDTOList"];

There''s much that''s wrong with this code, but it will work, and it seems you''re taking baby steps for now, so I don''t want to overload you with detail. I assume no-one is using this code, I can''t imagine someone who doesn''t know what the session is, would be paid to write web code.

private void Allocate()
      {

          List<ResourceDTO> objResourceList = new List<ResourceDTO>();

          objResourceList = (List<ResourceDTO>)Session["ResourceDTOList"];

          List<ProblemDto> objproblemlist = new List<ProblemDto>();
          objproblemlist = (List<ProblemDto>)Session["ProblemDtoList"];

          TableHeaderRow hrow = new TableHeaderRow();
          TableHeaderCell hcell1 = new TableHeaderCell();
          hcell1.Text = "&nbsp;";
          hrow.Controls.Add(hcell1);
          foreach (ResourceDTO item in objResourceList)
          {
              TableHeaderCell hcell2 = new TableHeaderCell();
              hcell2.Text = item.ItemName;
              hrow.Controls.Add(hcell2);
          }
          Table1.Controls.Add(hrow);

          foreach (ProblemDto problem in objproblemlist)
          {
              TableHeaderRow hrow1 = new TableHeaderRow();
              TableHeaderCell hcell3 = new TableHeaderCell();
              hcell3.Text = problem.Resource_Name;
              hrow1.Controls.Add(hcell3);
              foreach (ResourceDTO resource in objResourceList)
              {
                  TableHeaderCell hcell4 = new TableHeaderCell();
                  TextBox txtProfit = new TextBox();
                  txtProfit.Width = 60;
                  hcell4.Controls.Add(txtProfit);
                  hrow1.Controls.Add(hcell4);
              }
              Table1.Controls.Add(hrow1);
          }
