程序冻结,定时器循环无休止

我的程序将"Z"键绑定到激活计时器的处理程序。计时器触发鼠标点击。

问题是,如果我按住Z超过5秒,它就会被卡住,在KeyUp上它不会触发,变量不会变为false,循环是无休止的,所以当键不再按下时,它会继续触发计时器的回调。阻止它的唯一方法是通过ALT+F4

我的代码在http://pastebin.com/rbCgY1rb

我从这里使用globalKeyboardHook

代码的关键部分是:

 private void keyDownCallback(object sender, KeyEventArgs e) {
                    if (e.KeyCode.ToString() == "Z") {
                            timer1.Enabled = true;
                            this.forceNoLoop = false;
                    } else if(e.KeyCode.ToString() == "X") {
                            timer1.Enabled = false;
                            this.forceNoLoop = true;
                    }
            }
            private void keyUpCallback(object sender, KeyEventArgs e) {
                    timer1.Enabled = false;
                    this.forceNoLoop = true;
            }
            private void timer1_Tick(object sender, EventArgs e) {
                    if (forceNoLoop) return;
        mouse_event(MOUSEEVENTF_LEFTDOWN, (uint)Cursor.Position.X, (uint)Cursor.Position.Y, 0, 0);
        mouse_event(MOUSEEVENTF_LEFTUP, (uint)Cursor.Position.X, (uint)Cursor.Position.Y, 0, 0);
                    lblClickStatus.Text = "clicked " + (this.clickTimes++) + " times";
            }

所以问题是:如何解决冻结问题?

程序冻结,定时器循环无休止

在启用/禁用计时器之前,可以尝试检查计时器的状态吗?

private void keyDownCallback(object sender, KeyEventArgs e) {
    if (e.KeyCode.ToString() == "Z") {
        if (!timer1.Enabled)
            timer1.Enabled = true;
    } else if (e.KeyCode.ToString() == "X") {
        if (timer1.Enabled)
            timer1.Enabled = false;
    }
}
