username=varchar(50)
password=varchar(50)
//sessionexample.aspx

SqlDataAdapter dap = new SqlDataAdapter("select * from login where username='"+name.Text+"' and password='"+pass.Text+"'",con);
DataSet ds = new DataSet();
dap.Fill(ds);
Session["username"] = ds.Tables[0].Rows[0][1].ToString();
Response.Redirect("sessionexample2.aspx");
