FolderInformation.GetFoldersAsync 方法

定义

命名空间:

Windows.Storage.BulkAccess

重载

GetFoldersAsync()	从当前文件夹中检索所有子文件夹。
GetFoldersAsync(CommonFolderQuery)	基于公共文件夹查询从当前文件夹中检索子文件夹。
GetFoldersAsync(CommonFolderQuery, UInt32, UInt32)	基于公共文件夹查询从当前文件夹中检索一系列子文件夹。

GetFoldersAsync()

从当前文件夹中检索所有子文件夹。

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

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

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

function getFoldersAsync()

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

返回

IAsyncOperation<IVectorView<StorageFolder>>

IAsyncOperation<IReadOnlyList<StorageFolder>>

此方法成功完成后，它将返回子文件夹 (类型 IVectorView) 的列表。 此列表中的每个子文件夹都由 StorageFolder 对象表示。
