如何在会话中存储多个值

问题描述：

我正在创建一个应用程序，在其中我从数据库中检索数据。我将数据存储在会话变量中并显示数据，但会话只显示一条记录。但在数据库中包含10条记录。我希望会话应显示10条记录。

i am creating an application in which i retrive data from database. i am store data in session variable and display a data but session display only one record. but in database contains 10 record . i want session should display 10 record.

protected void Page_Load(object sender, EventArgs e)
   {
       SqlConnection con = new SqlConnection("Data Source=Aarambh;Initial Catalog=rebuild_technology;Integrated Security=True");
       SqlCommand cmd = new SqlCommand("select * from content_managment ", con);
       DataSet ds = new DataSet("temp");
       SqlDataAdapter ad = new SqlDataAdapter();

       ad.SelectCommand = cmd;
       ad.Fill(ds);
      // DataRow dr = ds.Tables[0].Rows[0];
       Session["divhtml_heading1"] = ds.Tables[0].Rows[0];
      // Session["divhtml_heading2"] = dr["divhtml_content"].ToString();

   }

答

你可以在会话中存储整个数据表，当你得到数据然后在datatable中转换会话。像那样

you can store whole datatable in session and when you getting data then cast session in datatable. like that

Session["SessionName"] = dt; // dt is data table

// get data like this

DataTable Dtbl= (DataTable)Session["SessionName"];

Session [divhtml_heading1 ] = ds.Tables [0] .Rows [0];

您在会话中存储了一个Row值，因此您只需返回一个值！

Do：

Session["divhtml_heading1"] = ds.Tables[0].Rows[0];
You stored one Row value in session and so you just get back one!

Do:

Session["divhtml_heading1"] = ds.Tables[0];
// Later to retrieve it
DataTable dt = (DataTable)Session["divhtml_heading1"];

试试这个

Hello Manohar

Just try this

SqlCommand cmd1 = new SqlCommand("select * from content_managment ", con);


SqlDataReader dr1 = cmd1.ExecuteReader();
var yourList = new List<int>();
if (dr1.HasRows)
{
    while (dr1.Read())
    {
       yourList.Add(Convert.ToInt32(dr1[0]));


    }
}
Session["divhtml_heading1"] = yourList;
dr1.Close();
cmd1.Dispose();
