在我可以手动添加更多员工到列表之前，如何初始化公共静态列表以至少拥有一个人？

Question

我一直在努力初始化我的公共静态列表myListPerson。 我想在我的列表中有一个人，每次我运行mvc项目时都是管理员。 我不确定我的代码中出错了什么，请在尝试初始化我的公开列表时帮助指出我的错误。

以下是我的控制器;

you just check your update query:
string SqlString = "UPDATE ProductList SET Pname = ?";

change to this:
string SqlString = "UPDATE ProductList SET Pname =@Pname ";

and change command parameter to pass scaler variable:
 cmd.Parameters.AddWithValue("@Pname", prdname.Text);

以下是我的视图显示我的员工名单

public class HomeController : Controller
{
    // holds all new people registered in system in this list
    public static List<Person> myListPerson = new List<Person>();
    Customer myCustomer = new Customer();
    Employee myEmployee = new Employee();



     //increamental customer number for ViewCustomer
        int Cus_Number = 1000;
public ActionResult ViewCustomer(string Name, string Surname, string Email, int Cell, int IDNumber)
        {
        Cus_Number = Cus_Number + 1;
        myCustomer.Name = Name;
        myCustomer.Surname = Surname;
        myCustomer.Email = Email;
        myCustomer.Cell = Cell;
        myCustomer.IDNumber = IDNumber;
        myCustomer.CustomerID = "Cus" + Cus_Number;
        myListPerson.Add(myCustomer);
        return View(myListPerson);
    }

    // GET: Index
    public ActionResult Index()
    {// I tried set admin values here but it still does not work when i check my view which displays people in list
        myEmployee.Name = "1";
        myEmployee.Surname = "1";
        myEmployee.Email = "1";
        myEmployee.Cell = 0;
        myEmployee.IDNumber = 0;
        myEmployee.EmployeeID = "Emp" + 1000;
        myListPerson.Add(myEmployee);
        return View(myListPerson);
    }
