定義

命名空間:

Windows.Storage.FileProperties

擷取與專案相關聯的指定屬性。

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

/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<IMap<winrt::hstring, IInspectable const&>> RetrievePropertiesAsync(IIterable<winrt::hstring> const& propertiesToRetrieve);

[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<IDictionary<string,object>> RetrievePropertiesAsync(IEnumerable<string> propertiesToRetrieve);

function retrievePropertiesAsync(propertiesToRetrieve)

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

參數

propertiesToRetrieve

IIterable<String>

IEnumerable<String>

IIterable<Platform::String>

IIterable<winrt::hstring>

集合，其中包含要擷取的屬性名稱。

傳回

IAsyncOperation<IMap<String,Object>>

IAsyncOperation<IDictionary<String,Object>>

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

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

當此方法順利完成時，它會傳回集合 (類型 IMap) ，其中包含指定的屬性和值做為索引鍵/值組。

實作

M:Windows.Storage.FileProperties.IStorageItemExtraProperties.RetrievePropertiesAsync(System.Collections.Generic.IEnumerable{System.String}) M:Windows.Storage.FileProperties.IStorageItemExtraProperties.RetrievePropertiesAsync(System.Collections.Generic.IEnumerable{Platform::String}) M:Windows.Storage.FileProperties.IStorageItemExtraProperties.RetrievePropertiesAsync(System.Collections.Generic.IEnumerable{winrt::hstring})

屬性

RemoteAsyncAttribute

備註

在 JavaScript 中，使用或完成來指定處理常式函式，以在傳回集合時擷取和處理集合。
