C#

Hello,

I am devloping C# WinApp to search and connect nearby bluethooth.
Hence I have downloaded required dll from 32feet.net.
But I am getting below error -

Unable to load DLL 'coredll.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

AND sometimes

The type initializer for 'InTheHand.Net.Sockets.BluetoothClient' threw an exception.

I have below code-

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using InTheHand.Net;
using InTheHand.Net.Sockets;
using InTheHand.Net.Bluetooth;
using InTheHand.Net.Ports;

namespace Bluethoot_Connet
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            textBox1.Clear();
            BluetoothClient bc = new BluetoothClient();
            BluetoothDeviceInfo[] divices = bc.DiscoverDevices(5);

            for (int i = 0; i < divices.Length; i++)
            {
                textBox1.Text = textBox1.Text + Environment.NewLine + "Name : " + divices[i].DeviceName + " Add : " + divices[i].DeviceAddress;
            }

        }
    }
}
