wpf - 将IEnumerable <T>与ObservableCollection <T>包装在一起

Question

从我的存储库中，我总是得到一个IEnumerable<T>。

在Ctor或ViewModel的方法中，我想将我的实体包装成ObservableCollection<T>，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); 

}

你会怎么做？

Answer 1

假设您有某种从Customer到CustomerViewModel的转换:

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