我已经编写了这个代码来实现一对多的关系,但它不起作用:

using (var connection = new SqlConnection(connectionString))
{
   connection.Open();

   IEnumerable<Store> stores = connection.Query<Store, IEnumerable<Employee>, Store>
                        (@"Select Stores.Id as StoreId, Stores.Name, 
                                  Employees.Id as EmployeeId, Employees.FirstName,
                                  Employees.LastName, Employees.StoreId 
                           from Store Stores 
                           INNER JOIN Employee Employees ON Stores.Id = Employees.StoreId",
                        (a, s) => { a.Employees = s; return a; }, 
                        splitOn: "EmployeeId");

   foreach (var store in stores)
   {
       Console.WriteLine(store.Name);
   }
}

任何人都可以发现错误吗？

这些是我的实体:

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public …
