GetPropertiesAsync()	擷取應用程式的屬性集集合，其中屬性集是索引鍵/值組。
GetPropertiesAsync(UInt32, UInt32)	在應用程式的索引內容屬性上執行查詢，並從結果集合中指定的開始索引傳回指定的屬性數目。

GetPropertiesAsync()

擷取應用程式的屬性集集合，其中屬性集是索引鍵/值組。

public:
 virtual IAsyncOperation<IVectorView<IMapView<Platform::String ^, Platform::Object ^> ^> ^> ^ GetPropertiesAsync() = GetPropertiesAsync;

/// [Windows.Foundation.Metadata.Overload("GetPropertiesAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<IVectorView<IMapView<winrt::hstring, IInspectable const&>>> GetPropertiesAsync();

[Windows.Foundation.Metadata.Overload("GetPropertiesAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<IReadOnlyList<IReadOnlyDictionary<string,object>>> GetPropertiesAsync();

function getPropertiesAsync()

Public Function GetPropertiesAsync () As IAsyncOperation(Of IReadOnlyList(Of IReadOnlyDictionary(Of String, Object)))

傳回

IAsyncOperation<IVectorView<IMapView<String,Object>>>

IAsyncOperation<IReadOnlyList<IReadOnlyDictionary<String,Object>>>

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

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

當這個方法完成時，它會將查詢結果當做 PropertyValue 實例的集合傳回。

unsigned int

uint32_t

要從結果集合中取得之第一個專案的索引。

maxItems

UInt32

unsigned int

uint32_t

要取得的專案數目上限。

傳回

IAsyncOperation<IVectorView<IMapView<String,Object>>>

備註

指定 startIndex 和 maxItems 對於搜尋結果的虛擬化或編頁存取很有用。
