当特定字符从serialport接收时关闭当前正在运行的表单 [英] Closing current running Form when a particular character is receiving from serialport

问题描述

嗨..

当我写下面的代码时，我收到了这个错误。

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

 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 - 线程操作无效：控制从其创建的线程以外的线程访问的Form1。

如何纠正此错误。我在谷歌搜索过。但我是这个区域的新手。谁能告诉我答案？

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?
