c# – 最小化应用程序表单会导致模式窗体关闭,但不会关闭Message

但是,如果我在MessageBox打开时以编程方式最小化应用程序的形式,则MessageBox不会关闭(即,当我将应用程序恢复到正常窗口状态时,消息框仍然显示).

这是我展示差异的示例代码：

public partial class Form1 : Form
    {
        // ... 

        private void showMessageBoxBtn_Click(object sender,EventArgs e)
        {
            timer1.Start();

            // This MessageBox does *not* get closed when the WindowState of Form1 is set to minimized in timer1_Tick
            MessageBox.Show(this,"MessageBox");
        }

        private void formShowDialogBtn_Click(object sender,EventArgs e)
        {
            timer1.Start();

            // This form gets closed when the WindowState of Form1 is set to minimized in timer1_Tick
            Form2 form2 = new Form2();
            form2.ShowDialog(); 
        }

        private void timer1_Tick(object sender,EventArgs e)
        {
            WindowState = FormWindowState.Minimized;
            timer1.Stop();
        }
    }

题：

有没有办法让Form表现得像MessageBox？
