將被呼叫的窗體加個timer, 並將其Modifiers屬性改為public, 寫下如下程式碼：

public partial class Form2 : Form

{

public Form2()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

}

private void timer1_Tick(object sender, EventArgs e)

{

button1_Click(this, null);

timer1.Enabled = false;

}

}

呼叫窗體寫下以下程式碼即可:

private void button1_Click(object sender, EventArgs e)

{

Form2 f = new Form2();

f.timer1.Enabled = true;

}
