Question

How can i shorter below codes than before?
i need short and simple method:
i dont want to use foreach loop because i have one value.

  public partial class Test : System.Web.UI.Page
    {
        StaffManagementEntities staffContext;
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                LoadStaffPersonel();
            }
        }

        void LoadStaffPersonel()
        {
            int selectedDepartman = Convert.ToInt32(Request.QueryString["SelectedDepartmanID"]);
            string name="";
            using (staffContext = new StaffManagementEntities())
            {

                var DepartmanName = from d in staffContext.Departman
                                    where d.ID == selectedDepartman
                                    select d;
                foreach (Departman d in DepartmanName)
                {
                    name = d.Name;
                }

                ObjectResult<StaffsPersonel> personalData = staffContext.GetPersonelData(name);
                gvPersonel.DataSource = personalData;
                gvPersonel.DataBind();

            }
        }

    }

How to use string value instead of ” var DepartmanName “

Answer 1

Something like:

string name = (from d in staffContext.Departman
               where d.ID == selectedDepartman
               select d.Name).First();

or:

string name = staffContext.Departman.Where(d=>d.ID == selectedDepartman)
                  .First().Name;
