  • Reference

Definition

Namespace:
Windows.Storage.Search

Overloads

GetFilesAsync()

Retrieves a list of all the files in the query result set.
GetFilesAsync(UInt32, UInt32)

Retrieves a list of files in a specified range.

GetFilesAsync()

Edit

Retrieves a list of all the files in the query result set.

public:
 virtual IAsyncOperation<IVectorView<StorageFile ^> ^> ^ GetFilesAsync() = GetFilesAsync;
/// [Windows.Foundation.Metadata.Overload("GetFilesAsyncDefaultStartAndCount")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<IVectorView<StorageFile>> GetFilesAsync();
[Windows.Foundation.Metadata.Overload("GetFilesAsyncDefaultStartAndCount")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<IReadOnlyList<StorageFile>> GetFilesAsync();
function getFilesAsync()
Public Function GetFilesAsync () As IAsyncOperation(Of IReadOnlyList(Of StorageFile))

Returns

IAsyncOperation<IVectorView<StorageFile>>

IAsyncOperation<IReadOnlyList<StorageFile>>

When this method completes successfully, it returns a list (type IVectorView) of files that are represented by StorageFile objects.

GetFilesAsync(UInt32, UInt32)

Edit

Retrieves a list of files in a specified range.

public:
 virtual IAsyncOperation<IVectorView<StorageFile ^> ^> ^ GetFilesAsync(unsigned int startIndex, unsigned int maxNumberOfItems) = GetFilesAsync;
/// [Windows.Foundation.Metadata.Overload("GetFilesAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<IVectorView<StorageFile>> GetFilesAsync(uint32_t const& startIndex, uint32_t const& maxNumberOfItems);
[Windows.Foundation.Metadata.Overload("GetFilesAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<IReadOnlyList<StorageFile>> GetFilesAsync(uint startIndex, uint maxNumberOfItems);
function getFilesAsync(startIndex, maxNumberOfItems)
Public Function GetFilesAsync (startIndex As UInteger, maxNumberOfItems As UInteger) As IAsyncOperation(Of IReadOnlyList(Of StorageFile))

Parameters

startIndex
UInt32

unsigned int

uint32_t

The zero-based index of the first file to retrieve. This parameter is 0 by default.

maxNumberOfItems
UInt32

unsigned int

uint32_t

The maximum number of files to retrieve. Use the max value of UInt32 (e.g. uint.MaxValue in C#, std::numeric_limits<uint32_t>::max() in C++. Some code in C++ may use -1 if implicit conversion is allowed) to retrieve all files. If the range contains fewer files than the max number, all files in the range are returned.

Returns

IAsyncOperation<IVectorView<StorageFile>>

IAsyncOperation<IReadOnlyList<StorageFile>>

When this method completes successfully, it returns a list (type IVectorView) of files that are represented by StorageFile objects.

Attributes
OverloadAttribute RemoteAsyncAttribute

Remarks

Use this overload to improve system performance by presenting a virtualized view of the query results that includes only the necessary subset of files. For example, if your app displays many files in a gallery you could use this range to retrieve only the files that are currently visible to the user.
