Public Shared Function CreateFileAsync (desiredName As String) As IAsyncOperation(Of StorageFile)

Parameters

desiredName
String

Platform::String

winrt::hstring

The desired name of the file to create.

If a file with the specified name already exists, a similar but unique name will be used. For example, if desiredName is "MyFileName.jpg" and a file by that name already exists in the Downloads folder, the new file will be created with a name like "MyFileName (1).jpg" instead.

Returns

IAsyncOperation<StorageFile>

When this method completes, it returns the new file as a StorageFile object.

Edit

public:
 static IAsyncOperation<StorageFile ^> ^ CreateFileAsync(Platform::String ^ desiredName, CreationCollisionOption option);
/// [Windows.Foundation.Metadata.Overload("CreateFileWithCollisionOptionAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]

public static IAsyncOperation<StorageFile> CreateFileAsync(string desiredName, CreationCollisionOption option);
function createFileAsync(desiredName, option)
Public Shared Function CreateFileAsync (desiredName As String, option As CreationCollisionOption) As IAsyncOperation(Of StorageFile)

Parameters

desiredName
String

Platform::String

winrt::hstring

The desired name of the file to create.

If there is an existing file in the current folder that already has the specified desiredName, the specified CreationCollisionOption determines how Windows responds to the conflict.

option
CreationCollisionOption

The enum value that determines how Windows responds if the desiredName is the same as the name of an existing file in the current folder.

Because the app can only access files in the Downloads folder that it created, you can't specify OpenIfExists or ReplaceExisting for this parameter.

Returns

IAsyncOperation<StorageFile>

When this method completes, it returns the new file as a StorageFile object.
