첨부파일에서 Interop.cs, WlanApi.cs 파일을 기존항목 추가 후 아래의 작업하면 됩니다.

using NativeWifi;

private void button2_Click(object sender, EventArgs e)
{
    var wlanClient = new WlanClient();

    foreach (WlanClient.WlanInterface wlanInterface in wlanClient.Interfaces)
    {
        Wlan.WlanBssEntry[] wlanBssEntries = wlanInterface.GetNetworkBssList();

        foreach (Wlan.WlanBssEntry wlanBssEntry in wlanBssEntries)
        {
            int rss = wlanBssEntry.rssi;

            byte[] macAddr = wlanBssEntry.dot11Bssid;

            var macAddrLen = (uint)macAddr.Length;
           
            var str = new string[(int)macAddrLen];
