为什么不响应按键事件：Key_Down

[zhji09]

this.KeyDown += new System.Windows.Forms.KeyEventHandler(this.Form2_KeyDown);

private void Form2_KeyDown(object sender, KeyEventArgs e)
{
if ((e.KeyCode == System.Windows.Forms.Keys.F1))
{
// Soft Key 1
// Not handled when menu is present.
}
if ((e.KeyCode == System.Windows.Forms.Keys.F2))
{
this.Close();

// Soft Key 2
// Not handled when menu is present.
}
if ((e.KeyCode == System.Windows.Forms.Keys.Up))
{
// Up
}
if ((e.KeyCode == System.Windows.Forms.Keys.Down))
{
// Down
}
if ((e.KeyCode == System.Windows.Forms.Keys.Left))
{
// Left
}
if ((e.KeyCode == System.Windows.Forms.Keys.Right))
{
// Right
}
if ((e.KeyCode == System.Windows.Forms.Keys.Enter))
{
// Enter
}
if ((e.KeyCode == System.Windows.Forms.Keys.D1))
{
// 1
}
if ((e.KeyCode == System.Windows.Forms.Keys.D2))
{
// 2
}
if ((e.KeyCode == System.Windows.Forms.Keys.D3))
{
// 3
}
if ((e.KeyCode == System.Windows.Forms.Keys.D4))
{
// 4
}
if ((e.KeyCode == System.Windows.Forms.Keys.D5))
{
// 5
}
if ((e.KeyCode == System.Windows.Forms.Keys.D6))
{
// 6
}
if ((e.KeyCode == System.Windows.Forms.Keys.D7))
{
// 7
}
if ((e.KeyCode == System.Windows.Forms.Keys.D8))
{
// 8
}
if ((e.KeyCode == System.Windows.Forms.Keys.D9))
{
// 9
}
if ((e.KeyCode == System.Windows.Forms.Keys.F8))
{
// *
}
if ((e.KeyCode == System.Windows.Forms.Keys.D0))
{
// 0
}
if ((e.KeyCode == System.Windows.Forms.Keys.F9))
{
// #
}

}

但是，我发现，他总是不响应，加断点得出此结论的
小弟，刚刚开始学习Mobile上SmartPhone开发，
还请不吝指教

要是C++倒还知道,这个看不懂.

我测试了，相应事件啊，按F2关键程序。你再操作之前，窗体获得了焦点了吗？你先点击一下窗体，然后在KeyDown
private void ContactSelector_KeyDown(object sender,KeyEventArgs e)
{
if ((e.KeyCode == System.Windows.Forms.Keys.F1))
{
// Soft Key 1
// Not handled when menu is present.
}
if ((e.KeyCode == System.Windows.Forms.Keys.F2))
{
this.Close();

// Soft Key 2
// Not handled when menu is present.
}
}
