如何防止在C#中按AcceptButton时表单被关闭

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if (e.CloseReason == CloseReason.UserClosing)
    {
        e.Cancel = true; // 取消表单关闭
    }
}

private void Form1_Load(object sender, EventArgs e)
{
    AcceptButton.Enabled = false; // 禁用AcceptButton
}

private void AcceptButton_Click(object sender, EventArgs e)
{
    // 执行需要的操作

    // 不关闭表单
}
