将 IEnumerable包装起来带有 ObservableCollection

Question

从我的存储库中，我总是得到一个 IEnumerable。

在 Ctor 或 ViewModel 的方法中，我想将我的实体包装到 ObservableCollection 中，如下所示：

private ObservableCollection<CustomerViewModel> customerViewModels;

public BillingViewModel(IService service)
{
   ...
   IEnumerable<Customer> customers = service.GetCustomers();

   // that will not work because of a different type
   customerViewModels = new ObservableCollection(customers); 

}

您会做什么？

Answer 1

假设您有某种从 Customer 到 CustomerViewModel 的转换：

customerViewModels = new ObservableCollection<CustomerViewModel>
    (customers.Select(c => ConvertToViewModel(c)));

Answer 2

如何将 Customer 转换为 CustomerViewModel？也许你只需要这样的东西：

customerViewModels = new ObservableCollection<CustomerViewModel>(
    from c in customers
    select new CustomerViewModel(c)
);
