I have searched for several days to no avail. I am trying to simply list to a text file the Image Device Names ie webcams using c#. I know I can use System.IO.Ports to get comports, which I am doing, but I cannot find a simple way to list the Image Devices.
I have been able to find the WIA devices with this code but not non-WIA Devices:
private static void DoWork()
{
var deviceManager1 = new DeviceManager();
for (int i = 1; (i <= deviceManager1.DeviceInfos.Count); i++)
{
// if (deviceManager1.DeviceInfos[i].Type !=
WiaDeviceType.VideoDeviceType) { continue; }
Console.WriteLine(deviceManager1.DeviceInfos[i].
Properties["Name"].get_Value(). ToString());
}
As I answered in this question , you can do it without external libraries by using WMI.
Add using System.Management;
and then:
public static List<string> GetAllConnectedCameras()
{
var cameraNames = new List<string>();
using (var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPEntity WHERE (PNPClass = 'Image' OR PNPClass = 'Camera')"))
{
foreach (var device in searcher.Get())
{
cameraNames.Add(device["Caption"].ToString());
}
}
return cameraNames;
}
I have a couple routes for you to check out.
Try adding a reference to Interop.WIA.dll (Microsoft Windows Image Acquisition Library) and using the following code to enumerate the devices. You can then filter for the relevant ones using a device property.
using System;
using WIA;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
DoWork();
Console.ReadKey();
}
private static void DoWork()
{
var deviceManager1 = new DeviceManager();
for (int i = 1; (i <= deviceManager1.DeviceInfos.Count); i++)
{
if (deviceManager1.DeviceInfos[i].Type == WiaDeviceType.CameraDeviceType|| deviceManager1.DeviceInfos[i].Type == WiaDeviceType.VideoDeviceType)
{
Console.WriteLine(deviceManager1.DeviceInfos[i].Properties["Name"].get_Value().ToString());
}
}
}
}
}
If that doesn't work, you can always try using DEVCON, which is a Microsoft tool. DEVCON allows device management from the command line. You could try invoking it with the appropriate flags and reading the output. ( http://www.robvanderwoude.com/devcon.php )
