Examples

The following example shows how to get an interface ID using GetDeviceSelector and the Windows.Devices.Enumeration API. It also shows how to pass it to FromId to get a StorageFolder for a removable storage device.

    Enum = Windows.Devices.Enumeration;

    // Enumerate removable storage devices.
    // The success callback selects the removable storage to use.
    function pickStorageToGetImageFrom() {
        Enum.DeviceInformation.findAllAsync(
        Windows.Devices.Portable.StorageDevice.getDeviceSelector(),
        null).then(
            successCallback,
            errorCallback);
    }

    // Handler that's called when removable storages are found.
    // storageDevices: A collection of type
    // Windows.Devices.Enumeration.DeviceInformationCollection.
    // This example just takes the first storage found in the list.
    function successCallback(storageDevices) {
        var removableStorage = null;
        if (storageDevices.length) {
            try {
                // Get the StorageFoler from the id for the first removable storage device
                removableStorage = Windows.Devices.Portable.StorageDevice.fromId(
                storageDevices.getAt(0).id);
                // document.getElementById("output").innerHTML = storageDevices.getAt(0).name; 
            } catch (e) {
                document.getElementById("output").innerHTML =
                "Error: " + e.message;
            }
            if (removableStorage != null) {
                getImageFiles(removableStorage);
            }
        } else {
            document.getElementById("output").innerHTML =
                "No removable storage devices were found.";
        }
    }

The following examples show the syntax of a call to FromId in C# and C++.

var folder = StorageDevice.FromId(deviceInformationId);

StorageFolder^ folder = StorageDevice::FromId(deviceInformationId);

Remarks

To access the device services, you must declare the device service in the capabilities section of the app manifest file. For a list of the GUIDs representing the device services, see Windows.Devices.Portable.

public : static StorageFolder FromId(PlatForm::String deviceId)public static StorageFolder FromId(String deviceId)Public Static Function FromId(deviceId As String) As StorageFolder// You can use this method in JavaScript.
