How to read Data from a ACR122U rfid tag reader in c#

Question

I have to use a ACR122U smartcard reader in order to implement a rfid tag reader function in c#.

Does anyone know a library which will allow me to manage this smartcard reader and perform basic IO operation ?

Thank you for reading.

I think this is the solution. You should connect this device to your computer and use it as an input device, via USB or any other serial port. Then you should go and implement this case HERE (very classic and useful). A similar case from our stackoverflow network HERE

I hope it may help to make good stuff.

private void btnReadTag_Click(object sender, EventArgs e)
{
    serialPort = new SerialPort();// if u r not used Serial Port Tool
    serialPort.PortName = "COM1";
    serialPort.BaudRate = 9600;
    serialPort.DataBits = 8;
    serialPort.Parity = Parity.None;
    serialPort.StopBits = StopBits.One;
    serialPort.Open();
    serialPort1.ReadTimeout = 2000;
    serialPort.DataReceived += new SerialDataReceivedEventHandler(Fun_DataReceived);
    serialPort.Close();
}
//Delegate for the Reading the Tag while RFID Card come to the Range.
string data = string.Empty;
private delegate void SetTextDeleg(string text);
void Fun_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
    Thread.Sleep(500);
    data = serialPort.ReadLine();
    this.BeginInvoke(new SetTextDeleg(Fun_IsDataReceived), new object[] { data });
}
private void Fun_IsDataReceived(string data)
{
    txtAccessCardNo.Text = data.Trim();
}
