public string BinaryToString(string data)
{
    List<byte> bytes = new List<byte>();
    for (int i = 0; i < data.Length; i += 8)
        bytes.Add(Convert.ToByte(data.Substring(i, 8), 2));
    return Encoding.ASCII.GetString(bytes.ToArray());
}

Finally, Add code to handle the Convert button click event.
