Question

I need to develop an winform app which reads attached cameras and microphones names from the system and displays it with radioboxes so that the user can select an attached microphone and camera and proceed to the next form where video conference happens….!!

But, I am not able to read attached hardware names of the system..Please suggest some way..!!

There’s an article on CodeProject that might help – Retrieving Hardware Information in C#:

This article will explain how to use WMI to access hardware information and properties. It will not set properties of hardware, only retrieve information about it.

WMI refers to Windows Management Instrumentation, and the majority of the code will use the System.Management namespace.

This sample I wrote will display a list of sound devices on your PC:

using System;
using System.Management;
using System.Management.Instrumentation;

namespace Test {
    class TestClass {
        [STAThread]
        static void Main(string[] args) {
            Console.WriteLine("Win32 SoundDevices\r\n===============================");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * from Win32_SoundDevice");
            foreach (ManagementObject soundDevice in searcher.Get()) {
                Console.WriteLine("Device found: {0}\n", soundDevice.ToString());
            }
            Console.WriteLine("Search complete.");
            Console.Read();
        }
    }
}

You’ll want to look at WMI Query Samples to help you figure out how to find the devices you’re looking to identify. Microsoft also has a WMI Code Creator utility that might help:

The WMI Code Creator tool allows you to generate VBScript, C#, and VB .NET code that uses WMI to complete a management task such as querying for management data, executing a method from a WMI class, or receiving event notifications using WMI.
