GetFoldersAsync()

检索 FolderInformation 对象的集合，这些对象包含有关集合中所有 StorageFolder 对象的信息。

public:
 virtual IAsyncOperation<IVectorView<FolderInformation ^> ^> ^ GetFoldersAsync() = GetFoldersAsync;

/// [Windows.Foundation.Metadata.Overload("GetFoldersAsyncDefaultStartAndCount")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<IVectorView<FolderInformation>> GetFoldersAsync();

[Windows.Foundation.Metadata.Overload("GetFoldersAsyncDefaultStartAndCount")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<IReadOnlyList<FolderInformation>> GetFoldersAsync();

function getFoldersAsync()

Public Function GetFoldersAsync () As IAsyncOperation(Of IReadOnlyList(Of FolderInformation))

返回

IAsyncOperation<IVectorView<FolderInformation>>

IAsyncOperation<IReadOnlyList<FolderInformation>>

此方法成功完成后，它将返回 folderInformation 对象的类型 IVectorView) (列表。
