Question

public List<SelectListItem> getTickerName()
{
    List<SelectListItem> lstTicker = new List<SelectListItem>();
    DataSet ds = new DataSet();

    //ds = BasicBoObj.getDatasetSP("sp_TickerNameForCompanies");
    ds = BasicBoObj.getDatasetSP("sp_ConfAdminCompanies");

    foreach (DataRow dr in ds.Tables[0].Rows)
    {
        lstTicker.Add(new SelectListItem { Text = Convert.ToString(dr["DisplayCompanyName"]), Value = Convert.ToString(dr["code"]) });
    }
    return lstTicker;
}

我想访问此Text的{{1}}。

在lstTicker中，我传递的是公司名称，在“值”中，我将ID传递给存储过程。

我怎么才能访问“Text”，其中我有公司名称，我想将其存储在数据库中

我正在访问值

Text

这将有效：

控制器/型号：

public class MyViewModelSO
{
    public int selectedValue { get; set; }
    public List<SelectListItem> tickers = HomeController.getTickerName();
}

public class HomeController : Controller
{
    [HttpPost]
    public ActionResult Index2007(MyViewModelSO myViewModel) 
    {
        //save
        var value = myViewModel.tickers.Where(r => r.Value == myViewModel.selectedValue.ToString()).
            Select(s => s.Text).ToList();

        //put breakpoint here to see value contains text
        //...rest of save

        return View(myViewModel);
    }

    public ActionResult Index2007()
    {
        var myViewModel = new MyViewModelSO();
        return View(myViewModel);
    }

    public static List<SelectListItem> getTickerName()
    {
        List<SelectListItem> lstTicker = new List<SelectListItem>();

        using (SqlConnection conn = new SqlConnection(@"Server=.\sqlexpress;DataBase={MyDB};Integrated Security=SSPI"))
        {
            conn.Open();
            SqlCommand cmd = new SqlCommand("sp_ConfAdminCompanies", conn);
            cmd.CommandType = CommandType.StoredProcedure;

            // execute the command
            using (SqlDataReader rdr = cmd.ExecuteReader())
            {
                // iterate through results, printing each to console
                while (rdr.Read())
                {
                    lstTicker.Add(new SelectListItem
                    {
                        Text = rdr["DisplayCompanyName"].ToString(),
                        Value = rdr["code"].ToString()
                    });

                }
            }
        }
        return lstTicker;
    }

您好，您可以使用 selectedItem.Text 的属性，这里是示例：

 [HttpPost]
    public ActionResult Index(FruitModel fruit)
    {
        fruit.Fruits = PopulateFruits();
        var selectedItem = fruit.Fruits.Find(p => p.Value == fruit.FruitId.ToString());
        if (selectedItem != null)
        {
            selectedItem.Selected = true;
            ViewBag.Message = "Fruit: " + selectedItem.Text;
            ViewBag.Message += "\\nQuantity: " + fruit.Quantity;
        }

        return View(fruit);
    }
