由于无法构建异步构造函数，可以使用静态异步方法来返回由私有构造函数创建的类实例。 public class ViewModel { public ObservableCollection<TData> Data { get; set; } //static async method that behave like a constructor async public static Task<ViewModel> BuildViewModelAsync() { ObservableCollection<TData> tmpData = await GetDataTask(); return new ViewModel(tmpData); } // private constructor called by the async method private ViewModel(ObservableCollection<TData> Data) { this.Data=Data; } } ... 展开详请
