How do I get COM port where my mobile device connected through a bluetooth stick? I can already get the name of the device eg. 'Nokia C2-01' with device.DeviceName using the 32feet library but how can I make it look like this? "Nokia c2-01 connected through COM7"?
First, you will need to get the device address using:
string comPort = GetBluetoothPort(device.DeviceAddress.ToString());
if(!string.IsNullOrWhiteSpace(comPort))
{
// enter desired output here
}
The GetBluetoothPort() method will look something like this:
using System.Management;
private string GetBluetoothPort(string deviceAddress)
{
const string Win32_SerialPort = "Win32_SerialPort";
SelectQuery q = new SelectQuery(Win32_SerialPort);
ManagementObjectSearcher s = new ManagementObjectSearcher(q);
foreach (object cur in s.Get())
{
ManagementObject mo = (ManagementObject)cur;
string pnpId = mo.GetPropertyValue("PNPDeviceID").ToString();
if (pnpId.Contains(deviceAddress))
{
object captionObject = mo.GetPropertyValue("Caption");
string caption = captionObject.ToString();
int index = caption.LastIndexOf("(COM");
if (index > 0)
{
string portString = caption.Substring(index);
string comPort = portString.
Replace("(", string.Empty).Replace(")", string.Empty);
return comPort;
}
}
}
return null;
}
This will return the port name i.e. COM7

I'm totally out of C# hence hanging a little here. I stole the code from https://stackoverflow.com/a/13175574 to read out all adapter settings available on the pc. So far so good.
What I need now is a way to check, which of the adapters are able to connect to an attached device with a given ip address.
I'd like to have a function like "bool CheckIfValidIP(IPAddress adapter, IPAddress IPv4Mask, IPAddress address)".
Can you help me here? I know it's pretty trivial :-/
Edit:
public static class IPAddressExtensions
{
public static IPAddress GetNetworkAddress(this IPAddress address, IPAddress subnetMask)
{
byte[] ipAdressBytes = address.GetAddressBytes();
byte[] subnetMaskBytes = subnetMask.GetAddressBytes();
if (ipAdressBytes.Length != subnetMaskBytes.Length)
throw new ArgumentException("Lengths of IP address and subnet mask do not match.");
byte[] broadcastAddress = new byte[ipAdressBytes.Length];
for (int i = 0; i < broadcastAddress.Length; i++)
{
broadcastAddress[i] = (byte)(ipAdressBytes[i] & (subnetMaskBytes[i]));
}
return new IPAddress(broadcastAddress);
}
public static bool IsInSameSubnet(IPAddress address2, IPAddress address, IPAddress subnetMask)
{
IPAddress network1 = address.GetNetworkAddress(subnetMask);
IPAddress network2 = address2.GetNetworkAddress(subnetMask);
return network1.Equals(network2);
}
}
This code shall do it. Is it safe to use?
A very simple example to get you in the right direction, this is created in .Net core 6:
using System.Net.NetworkInformation;
using System.Net.Sockets;
NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
var adaptertList = new List<NetworkInterface>();
const string IpAddressToValidate = "192.168.1.1"; //Both of these values can be retrieved from appsetting.json file
const string IpV4MaskToValidate = "255.255.255.0";
adaptertList = GetValidAdapterList(interfaces);
List<NetworkInterface> GetValidAdapterList(NetworkInterface[] interfaces) {
var adaptertList = new List<NetworkInterface>();
foreach (var adapter in interfaces) {
var ipProps = adapter.GetIPProperties();
foreach (var ip in ipProps.UnicastAddresses) {
if ((adapter.OperationalStatus == OperationalStatus.Up)//Check for any conditions appropriate to your case
&& (ip.Address.AddressFamily == AddressFamily.InterNetwork)) {
if (CheckIsValidIP(ip.Address.ToString(), ip.IPv4Mask.ToString(), IpAddressToValidate, IpV4MaskToValidate)) {
adaptertList.Add(adapter);
continue;//If IP found exit the loop, as the adapter is already added
}
}
}
}
return adaptertList;
}
bool CheckIsValidIP(string ipAddress, string ipV4Mask, string validIpAddress, string validIpV4Mask) {
return (ipAddress == validIpAddress && ipV4Mask == validIpV4Mask);
}
This code will return a list of all the adapter in the machine that meet the Ip address and ipv4mask criteria.
I have a Modbus TCP/IP to MODBUS RTU converter , which comes with a default IP of 192.168.0.1 . I need to develop a small c# Winform app to change this device's IP address to any desired IP address. How do I do that?.
You could do it with WMI (Windows Management Instrumentation).
First, you have to add the reference for System.Management to your Project.
Second, you need to find the NetworkInterface for your network connection by name:
using System.Net.NetworkInformation;
using System.Management;
public class NetworkManager
{
public static NetworkInterface GetNetworkInterface(string sName)
{
NetworkInterface NetInterface = null;
// Precondition
if (sName == "") return null;
NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface ni in interfaces)
{
if (ni.Name == sName)
{
NetInterface = ni;
break;
}
}
return NetInterface;
}
Third, you have to create a ManagementObject for your NetworkInterface:
public static ManagementObject GetNetworkAdapterManagementObject(NetworkInterface NetInterface)
{
ManagementObject oMngObj = null;
// Precondition
if (NetInterface == null) return null;
string sNI = NetInterface.Id;
ManagementClass oMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection oMOC = oMC.GetInstances();
foreach (ManagementObject oMO in oMOC)
{
string sMO = oMO["SettingID"].ToString();
if (sMO == sNI)
{
// Found
oMngObj = oMO;
break;
}
}
return oMngObj;
}
Fours, you can set the ipadress with:
public static bool SetIPAdress(ManagementObject oMO, string[] saIPAdress, string[] saSubnetMask)
{
bool bErg = false;
try
{
// Precondition
if (oMO == null) return false;
if (saIPAdress == null) return false;
if (saSubnetMask == null) return false;
// Get ManagementBaseObject
ManagementBaseObject oNewIP = null;
oNewIP = oMO.GetMethodParameters("EnableStatic");
oNewIP["IPAddress"] = saIPAdress;
oNewIP["SubnetMask"] = saSubnetMask;
// Invoke
oMO.InvokeMethod("EnableStatic", oNewIP, null);
// Alles ok
bErg = true;
}
catch (Exception ex)
{
Console.WriteLine("SetIPAdress failed: " + ex.Message);
}
return bErg;
}
}
Now you can use it, for example in a button click event handler:
private void button1_Click(object sender, EventArgs e)
{
string sConn = "LAN-Verbindung";
NetworkInterface oNI = NetworkManager.GetNetworkInterface(sConn);
ManagementObject oMO = NetworkManager.GetNetworkAdapterManagementObject(oNI);
string sIPAdress = "192.168.1.1";
string sSubnetMask = "255.255.255.0";
string[] saIPAdress = {sIPAdress};
string[] saSubnetMask = {sSubnetMask};
if (NetworkManager.SetIPAdress(oMO, saIPAdress, saSubnetMask))
{
Console.WriteLine("Yes...");
}
}
Depending on the policies on your pc, may be you have to run the program as Administrator...
Is there any way to get computer's mac address when there is no internet connection in c#?
I'am able to get when I have connection but not able to get when I am offline. But strongly I need the mac address for my work.
My online code;
var macAddr =
(from nic in NetworkInterface.GetAllNetworkInterfaces()
where nic.OperationalStatus == OperationalStatus.Up
select nic.GetPhysicalAddress().ToString()).FirstOrDefault();
From WMI:
public static string GetMACAddress1()
{
ManagementObjectSearcher objMOS = new ManagementObjectSearcher("Select * FROM Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMOS.Get();
string macAddress = String.Empty;
foreach (ManagementObject objMO in objMOC)
{
object tempMacAddrObj = objMO["MacAddress"];
if (tempMacAddrObj == null) //Skip objects without a MACAddress
{
continue;
}
if (macAddress == String.Empty) // only return MAC Address from first card that has a MAC Address
{
macAddress = tempMacAddrObj.ToString();
}
objMO.Dispose();
}
macAddress = macAddress.Replace(":", "");
return macAddress;
}
From System.Net namespace:
public static string GetMACAddress2()
{
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
String sMacAddress = string.Empty;
foreach (NetworkInterface adapter in nics)
{
if (sMacAddress == String.Empty)// only return MAC Address from first card
{
//IPInterfaceProperties properties = adapter.GetIPProperties(); Line is not required
sMacAddress = adapter.GetPhysicalAddress().ToString();
}
} return sMacAddress;
}
Slightly modified from How to get the MAC address of system - C-Sharp Corner
You can use WMI in C# (System.Management) to get a list of Win32_NetworkAdapter's which contains a MACAddress property.

You'll need to resort to WMI. With the proper privileges on the SQL Server machine, you can get the serial number of the hard-drives on it. See here for an example on retrieving the hard-disk's serial number using WMI.
You'll need to figure out which disk holds SQL Server and how to access the SQL Server machine on your own.
You have to do it in 3 stages:
The connection string of the data source gives you the name of the machine on which SQL Server is installed
You must then query the machine to find out the drive which drive SQL Server is installed on
You can then use the code supplied by others here to get the serial number
I am developing a C# .NET 2.0 application wherein I need to scan for an attached HID. How can this be done? Because it is a HID, Windows does not assign a COM port to it. I only need to programmatically determine if the device is attached. Thank you.
ADDITIONAL INFORMATION
When I connect the USB device to my computer two entries appear under Human Interface Devices in the Device Manager. Clicking into their Properties yields this information in their respective Details tabs:
HID-compliant device
Device Instance Id: HID\VID_1795&PID_6004\7&2694D932&0&0000
USB Human Interface Device
Device Instance Id: USB\VID_1795&PID_6004\B973000000EB0D00
In the WMI Code Creator select these options:
Namespace: root\WMI
Class: MSWmi_PnPInstanceNames
Select InstanceNames from the Results box for the following code:
using System;
using System.Management;
using System.Windows.Forms;
namespace WMISample
{
public class MyWMIQuery
{
public static void Main()
{
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\WMI",
"SELECT * FROM MSWmi_PnPInstanceNames");
foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("-----------------------------------");
Console.WriteLine("MSWmi_PnPInstanceNames instance");
Console.WriteLine("-----------------------------------");
Console.WriteLine("InstanceName: {0}", queryObj["InstanceName"]);
}
}
catch (ManagementException e)
{
MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}
}
}
}
Here is an example of enumerating Hid devices on Windows:
public static ConnectedDeviceDefinition GetDeviceDefinition(string deviceId, SafeFileHandle safeFileHandle)
{
try
{
var hidAttributes = GetHidAttributes(safeFileHandle);
var hidCollectionCapabilities = GetHidCapabilities(safeFileHandle);
var manufacturer = GetManufacturer(safeFileHandle);
var serialNumber = GetSerialNumber(safeFileHandle);
var product = GetProduct(safeFileHandle);
return new ConnectedDeviceDefinition(deviceId)
{
WriteBufferSize = hidCollectionCapabilities.OutputReportByteLength,
ReadBufferSize = hidCollectionCapabilities.InputReportByteLength,
Manufacturer = manufacturer,
ProductName = product,
ProductId = (ushort)hidAttributes.ProductId,
SerialNumber = serialNumber,
Usage = hidCollectionCapabilities.Usage,
UsagePage = hidCollectionCapabilities.UsagePage,
VendorId = (ushort)hidAttributes.VendorId,
VersionNumber = (ushort)hidAttributes.VersionNumber,
DeviceType = DeviceType.Hid
};
}
catch (Exception)
{
return null;
}
}

Here is a similar thing for Windows 10 (UWP):

{
var aqsFilter = GetAqsFilter(deviceDefinition.VendorId, deviceDefinition.ProductId);
var deviceInformationCollection = await wde.DeviceInformation.FindAllAsync(aqsFilter).AsTask();
var deviceDefinitions = deviceInformationCollection.Select(d => GetDeviceInformation(d, DeviceType));
var deviceDefinitionList = new List<ConnectedDeviceDefinition>();
foreach (var deviceDef in deviceDefinitions)
{
var connectionInformation = await TestConnection(deviceDef.DeviceId);
if (connectionInformation.CanConnect)
{
await Task.Delay(1000);
deviceDef.UsagePage = connectionInformation.UsagePage;
deviceDefinitionList.Add(deviceDef);
}
}
return deviceDefinitionList;
}

Android (https://github.com/MelbourneDeveloper/Device.Net/blob/77439b1ab0f4b3ad97376e4e62c7efac0a749783/src/Usb.Net.Android/AndroidUsbDeviceFactory.cs#L31):
public Task<IEnumerable<ConnectedDeviceDefinition>> GetConnectedDeviceDefinitions(FilterDeviceDefinition deviceDefinition)
{
return Task.Run<IEnumerable<ConnectedDeviceDefinition>>(() =>
{
//TODO: Get more details about the device.
return UsbManager.DeviceList.Select(kvp => kvp.Value).Where(d => deviceDefinition.VendorId == d.VendorId && deviceDefinition.ProductId == d.ProductId).Select(GetAndroidDeviceDefinition).ToList();
});
}
Using Hid.Net, you can enumerate devices in the same way on any platform like below. See the full article.
var devices = await DeviceManager.Current.GetConnectedDeviceDefinitions(new FilterDeviceDefinition { VendorId = 0x1209, ProductId = 0x53C1 });
foreach (var device in devices)
{
Debug.WriteLine(device.DeviceId);
}
