ContentIndexer.RetrievePropertiesAsync 方法

定義

命名空間:

Windows.Storage.Search

根據指定的內容識別碼取得內容屬性。

public:
 virtual IAsyncOperation<IMapView<Platform::String ^, Platform::Object ^> ^> ^ RetrievePropertiesAsync(Platform::String ^ contentId, IIterable<Platform::String ^> ^ propertiesToRetrieve) = RetrievePropertiesAsync;

IAsyncOperation<IMapView<winrt::hstring, IInspectable const&>> RetrievePropertiesAsync(winrt::hstring const& contentId, IIterable<winrt::hstring> const& propertiesToRetrieve);

public IAsyncOperation<IReadOnlyDictionary<string,object>> RetrievePropertiesAsync(string contentId, IEnumerable<string> propertiesToRetrieve);

function retrievePropertiesAsync(contentId, propertiesToRetrieve)

Public Function RetrievePropertiesAsync (contentId As String, propertiesToRetrieve As IEnumerable(Of String)) As IAsyncOperation(Of IReadOnlyDictionary(Of String, Object))

參數

contentId

String

Platform::String

winrt::hstring

內容屬性的識別碼。

propertiesToRetrieve

IIterable<String>

IEnumerable<String>

IIterable<Platform::String>

IIterable<winrt::hstring>

根據 contentId擷取的屬性。

傳回

IAsyncOperation<IMapView<String,Object>>

IAsyncOperation<IReadOnlyDictionary<String,Object>>

IAsyncOperation<IMapView<Platform::String,Platform::Object>>

IAsyncOperation<IMapView<winrt::hstring,IInspectable>>

當這個方法完成時，它會傳回擷取的屬性做為索引鍵/值組的對應。
