To get provider from ManagementObjectSearcher Win32_PnPEntity - c#

I am searching for my USB to Serial converter. I have two objectives:
To get the USB Port Number
To get the Provider
Here under is the screenshot from my Device Manager
Now my motto is to recognize this USB to Serial Bridge which is provided by ATEN, However I am not specifically looking for the ATEN thing, just I need to know how to query ManagementObject
Because if I look for Caption for some systems it is ATEN USB to Serial Bridge and for some systems it is USB-to-Serial Comm. Port, and maybe for some other it will become something else. What never changes is the Provider - "ATEN"
Following is my code:
Now I have did something here under to get/extract data from **CAPTION**
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_PnPEntity WHERE Caption like '%ATEN USB to Serial Bridge%'"))
{
foreach (ManagementObject queryObj in searcher.Get())
{
foreach (PropertyData prop in queryObj.Properties)
{
listBox1.Items.Add(String.Format("{0}: {1}", prop.Name, prop.Value));
}
string s = queryObj["Caption"].ToString();
// Here under i play with the string `s` to get the `CCOM21`
int start = s.IndexOf("(");
int end = s.IndexOf(")");
result = s.Substring(start, end - start);
result = result.Replace("(", "");
list.Items.Add(result);
}
}
I know its not the right way to do but how I can get the COM21 port and Provider - ATEN by query ManagementObject. Or is there any other direct way to do this.

Incorrect hard drive serial number

I am currently developing a program that will allow me to detect the serial number of all hard drives in a computer and display them as a barcode.
I have it working on my current machine (Windows 10) and it gets the correct serial numbers (same as what's on the hard drive label) but when I try and use it on a different machine (Windows 7) it just outputs a long string of numbers.
The program is able to detect and output the serial number on my usb fine.
var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
foreach (ManagementObject wmi_HD in searcher.Get())
{
HardDrive hd = new HardDrive();
hd.Model = wmi_HD["Model"].ToString();
hd.SerialNum = Convert.ToString(wmi_HD.GetPropertyValue("SerialNumber"));
hdCollection.Add(hd);
}
This is the current code I am using but the serial number it outputs is: 5635454d4338414e202020202020202020202020
I have tried Win32_LogicalDrive and Win32_Volume but they output the same string.
I have also tried this code snippet:
ManagementClass driveClass = new ManagementClass("Win32_DiskDrive");
ManagementObjectCollection drives = driveClass.GetInstances();
foreach (ManagementObject drive in drives)
{
HardDrive hd = new HardDrive();
hd.Model = drive["Name"].ToString();
//hd.SerialNum = drive.GetPropertyValue("SerialNumber").ToString();
hd.SerialNum = drive["SerialNumber"].ToString();
}
But this also does not work on the Windows 7 machine.
How could I fix my problem?

How to detect Cameras attached to my machine using C#

I am able to know the sound devices and USB Devices attached to my PC but not getting any way to find Cameras attached to my machine.
Used below code to get Sound Devices
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("Device found: {0}\n", soundDevice.GetPropertyValue("ProductName"));
}
Console.WriteLine("Search complete.");
I wrote a solution that worked well for me. This method found two USB cameras and an integrated camera on my laptop.
private static async Task ListAllCamerasAsync()
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM win32_PNPEntity WHERE PnPClass='Camera'");
var collection = await Task.Run(() => { return searcher.Get(); });
var cameraIndex = 0;
foreach (ManagementObject cameraDevice in collection)
{
Console.WriteLine($"Camera {cameraIndex}: {cameraDevice["Name"]}");
cameraIndex++;
}
}
This tool will prove helpful:

I'm fairly certain there's no equivalent string you can send to ManagementObjectSearcher() for webcams specifically. There is the "Win32_USBControllerDevice" which you can then determine if it is a webcam or not.
A better solution altogether is to take advantage of DirectShow.NET

Detecting input and output audio devices separately in C#

I am trying to search for all available sound input and outut devices and adding their names into a ComboBox.
I am using this code (found here at stackoverflow in a similiar question):
ManagementObjectSearcher mo = new ManagementObjectSearcher("select * from Win32_SoundDevice");
foreach (ManagementObject soundDevice in mo.Get())
{
string deviceId = soundDevice.GetPropertyValue("DeviceId").ToString();
string name = soundDevice.GetPropertyValue("Name").ToString();
comboBox1.Items.Add(name);
}
But this seems to select all available devices, I need to separate input devices and output devices. Is there a simple way of editing this code, or is there a more sophisticated method needed?

How to get network adapter index?

From code I want to force a Windows machine to use a specific network adapter for all connections to a specific IP address.
I plan to do so by using the ROUTE ADD command line tool, but this requires that I know in advance the network adapters' index number (as it must be given to the ROUTE ADD command).
QUESTION: How can I programmatically retrieve a network adapter's index, given I know its name?
I'm aware that ROUTE PRINT shows me the information I need (the index numbers of all network adapters present), but there must be a way to get that information programmatically too (C#)?
Note, that I don't like parsing the text output from ROUTE PRINT, as the text format may change with different Windows versions.
You can obtain the interface index of your network adapter
by using the .Net NetworkInterface (and related) classes.
Here is a code example:
static void PrintInterfaceIndex(string adapterName)
{
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
Console.WriteLine("IPv4 interface information for {0}.{1}",
properties.HostName, properties.DomainName);
foreach (NetworkInterface adapter in nics)
{
if (adapter.Supports(NetworkInterfaceComponent.IPv4) == false)
{
continue;
}
if (!adapter.Description.Equals(adapterName, StringComparison.OrdinalIgnoreCase))
{
continue;
}
Console.WriteLine(adapter.Description);
IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
IPv4InterfaceProperties p = adapterProperties.GetIPv4Properties();
if (p == null)
{
Console.WriteLine("No information is available for this interface.");
continue;
}
Console.WriteLine(" Index : {0}", p.Index);
}
}
Then just call this function with the name of your network adapter:
PrintInterfaceIndex("your network adapter name");
You can also obtain the InterfaceIndex of your network adapter
by using the Win32_NetworkAdapter WMI class. The Win32_NetworkAdapter class
contains a property called InterfaceIndex.
So, to retrieve the InterfaceIndex for a network adapter with a given
name, use the following code:
ManagementScope scope = new ManagementScope("\\\\.\\ROOT\\cimv2");
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_NetworkAdapter WHERE Description='<Your Network Adapter name goes here>'");
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query))
{
using (ManagementObjectCollection queryCollection = searcher.Get())
{
foreach (ManagementObject mo in queryCollection)
{
Console.WriteLine("InterfaceIndex : {0}, name {1}", mo["InterfaceIndex"], mo["Description"]);
}
}
}
If you do not want to use WMI you could also use the Win32 API function
GetAdaptersInfo in combination with the IP_ADAPTER_INFO struct.
You will find an example here pinvoke.net.
have you looked into using C#'s system.net.networkinformation interface?
http://msdn.microsoft.com/en-us/library/system.net.networkinformation.networkinterface.getallnetworkinterfaces.aspx
I'm not familiar with ROUTE ADD, but you can theoretically marry up information from one with the other.

How to distinguish between USB and floppy devices?

I'm trying to recognize drives types by looping around DriveInfo.GetDrives() result.
But for both USB and floppy I get the same DriveType.Removable value.
How can I distinguish between them?
You can use WMI (Windows Management Instrumentation) to get more than just what's in the DriveInfo class. In this case, you can get the interface type, which will be "USB" for USB drives.
Sample code is below. You need to add a reference to System.Management.
using System.Management;
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_DiskDrive");
foreach(ManagementObject queryObj in searcher.Get())
{
foreach(ManagementObject o in queryObj.GetRelated("Win32_DiskPartition"))
{
foreach(ManagementBaseObject b in o.GetRelated("Win32_LogicalDisk"))
{
Debug.WriteLine(" #Name: {0}", b["Name"]);
}
}
// One of: USB, IDE
Debug.WriteLine("Interface: {0}", queryObj["InterfaceType"]);
Debug.WriteLine("--------------------------------------------");
}
}
catch (ManagementException f)
{
Debug.WriteLine(f.StackTrace);
}
For reference, this MSDN page documents the full list of accessible properties (since you don't get autocomplete on this).
The CD Drive And floppy Drive is not ready so you can try this :
foreach (var dr in DriveInfo.GetDrives())
{
if (dr.IsReady == true)
{
Console.WriteLine(string.Format("name : {0} type : {1}", dr, dr.DriveType));
}
}
This is Easy Way to distinguish Between USB and floppy devices
