我在我的代碼中添加了這個：namespace uartToCs_version_2._0{ public partial class formMain : Form { ==> public static SerialPort serial = new SerialPort();但是我沒有使用設計選項卡，那么我應該如何進行事件處理（使用當前設置，我也可以在其他形式中使用它，這仍然可能嗎）？

您可以在任何方法中注冊事件，例如 Load() 或在構造函數(shù)中。我使用了下面的構造函數(shù)。在設置所有需要的屬性之前，您無法注冊事件。我沒有顯示設置代碼。
public partial class Form1 : Form
{
public static SerialPort serial = new SerialPort();
public Form1()
{
InitializeComponent();
serial.DataReceived += new SerialDataReceivedEventHandler(serial_DataReceived);
}
private void serial_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
}
}

public Form1()
{
InitializeComponent();
//add DataReceived event of serial
Form1.serial.DataReceived += serial_DataReceived;
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
//remove DataReceived event of serial
Form1.serial.DataReceived -= serial_DataReceived;
}
void serial_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
//process data here
}
