String
Platform::String
winrt::hstring
An AQS device interface selector string that filters the DeviceInformation objects to enumerate. Typically this string is retrieved from the GetDeviceSelector method of a class that interacts with devices. For example, GetDeviceSelector retrieves the string for the StorageDevice class.
An iterable list of additional properties to include in the Properties property of the DeviceInformation objects in the enumeration results. For more info on what the properties represent, see Device information properties.
The specific type of device to find.
- settings
- IDeviceEnumerationSettings
Enumeration settings come from a device API's GetDeviceEnumerationSettings method, and contain opaque data. An object implementing this must also implement the IDeviceEnumerationSettings interface.
Returns
An asynchronous operation object which, when it completes, contains the DeviceInformation objects.

Remarks
Important
This method is not available using JavaScript. If you try to use it, your code will instead call FindAllAsync(DeviceClass) with an invalid class and return a collection with all devices. Instead, you should use FindAllAsync(String, IIterable(String) with null as the second parameter if no other properties are needed.
