Hi..
When I write the following code I got this error.

C#

 byte[] byte_buffer = new byte[20];

 private void serialPort1_DataReceived(objectsender,System.IO.Ports.SerialDataReceivedEventArgs e)
        {
            int bytes = serialPort1.BytesToRead;
           
            serialPort1.Read(byte_buffer, 0, bytes);

            count++;
            if (byte_buffer[0] == startup)
            {
               
                 this. Close();//Error
                Application. Run(new Form4());
               
               
              }
}

Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on.
How can I rectify this error.? I searched in Google..But am new to this area.so can anyone tell me the answer?
