Устройства eSCL

В этом разделе

Диспетчер устройств eSCL позволяет программно получить список устройств. Список устройств можно получить с помощью свойства EsclDeviceManager.Devices. Информацию об открытом устройстве можно получить с помощью свойства EsclDeviceManager.OpenedDevice.

Вот пример, демонстрирующий, как открыть диспетчер устройств eSCL и отобразить информацию обо всех доступных устройствах eSCL:

/// <summary>
/// Opens eSCL device manager and displays information about available local eSCL image scanners.
/// </summary>
void GetEsclDevicesInfo()
{
    // create eSCL device manager
    using (Vintasoft.EsclImageScanning.EsclDeviceManager deviceManager = new Vintasoft.EsclImageScanning.EsclDeviceManager())
    {
        // open device manager
        deviceManager.Open();

        System.DateTime startTime = System.DateTime.Now;
        // while eSCL devices are not found
        while (deviceManager.Devices.Count == 0 && System.DateTime.Now.Subtract(startTime).Microseconds < 5000)
        {
            System.Threading.Thread.Sleep(10);
        }
        // get count of eSCL devices
        int deviceCount = deviceManager.Devices.Count;
        if (deviceCount == 0)
        {
            System.Console.WriteLine("Devices are not found.");
            return;
        }

        Vintasoft.EsclImageScanning.EsclDeviceCollection devices = deviceManager.Devices;
        // for each eSCL device
        for (int i = 0; i < devices.Count; i++)
        {
            // output the device name
            System.Console.WriteLine(string.Format("Device '{0}'", devices[i].Name));
        }
    }
}

                Dim startTime As System.DateTime = System.DateTime.Now
