How do I get C# to give me the start value (which would be 10.10.0.1) and the end value (which would be 10.10.255.255)?

static string GetRange(IPAddress address, IPAddress subnetMask)
{
    IPAddress ip = address;

    byte[] ipBytes = ip.GetAddressBytes();
    byte[] maskBytes = subnetMask.GetAddressBytes();

    byte[] startIPBytes = new byte[ipBytes.Length];
    byte[] endIPBytes = new byte[ipBytes.Length];

    for (int i = 0; i < ipBytes.Length; i++)
    {
        startIPBytes[i] = (byte)(ipBytes[i] & maskBytes[i]);
        endIPBytes[i] = (byte)(ipBytes[i] | ~maskBytes[i]);
    }

    IPAddress startIP = new IPAddress(startIPBytes);
    IPAddress endIP = new IPAddress(endIPBytes);

    return startIP.ToString() + " -- " + endIP.ToString();
}

i need to use it as DataSource

System.IO.FileInfo[] fi = (new System.IO.DirectoryInfo ( "C:\\" )).GetFiles ( "*.txt" ) ;

listBox1.DataSource = fi ;

comboBox1.DataSource = fi ;

checkedListBox1.Items.AddRange ( fi ) ;
