Wpf 包装一个IEnumerable<；T>；以可观察的方式收集<；T>；

从我的存储库中，我总是得到一个

IEnumerable

在我的ViewModel的Ctor或方法中，我希望将我的实体包装成一个

可观察集合

，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); 

}

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

private observeCollection客户服务模型；
公共计费视图模型（iSeries服务）
{
...
IEnumerable customers=service.GetCustomers（）；
//这将不起作用，因为类型不同
CustomerServiceWModels=新的ObservableCollection（客户）；
}

---

您会怎么做？

如何将

客户

转换为

客户服务模型

？也许你只需要这样的东西：

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); 

}

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

CustomServiceWModels=新的ObservableCollection(
从c到客户
选择新的CustomerViewModel（c）
);

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

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

CustomServiceWModels=新的ObservableCollection
（customers.Select（c=>ConvertToViewModel（c））；
