Question

我想用椭圆进行简单的模拟。在用户界面中，将有一个按钮。用户将按下按钮，然后以1秒的间隔，椭圆将被绘制到pictureBox。像交通信号灯......

我想我需要使用Timer Event，但不知道怎么做。我怎样才能实现它？

我最诚挚的问候......

我不太明白你问的目的，但我猜你可以通过阅读这些链接来了解。

first将指导您完成有关计时器控制的大部分知识。

second会让您了解绘制省略号的方法。

关于如何构建代码，简单地说，我得到启动计时器的按钮，然后timerElapsed事件将控制图片框中每隔1秒创建一个椭圆。

有关更多解释，我认为最好将一些代码放在一起，以便我们更好地了解您的意图。然后我们可以提供更多帮助。希望这会有所帮助。

这将创建省略号，直到计时器停止，你可以添加一个按钮来停止timer1：

public void Button1_Click(Object sender, EventArgs e)
{
    timer1.Interval = 1000;
    timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
    DrawMap ortamcizdir = new DrawMap(p_box_map, bmp, ZoomControl, panel1);
    DrawCell hucrecizdir = new DrawCell (p_box_map, bmp, a, ZoomControl, ZoomKontrolBolen);
}

不要忘记您需要将计时器拖到设计上，然后双击属性窗格上的勾选事件。

这个答案认为DrawCell类没有任何问题。

<强> [EDIT2]

我正在考虑我发布的内容，这将创建省略号，直到计时器停止。因此，您可能希望添加while语句来控制要绘制的椭圆数。检查this link以查看实施该方法的其他方法。

通过这种方式，您可以设置要绘制的省略号，这是一个示例，但有很多方法可以将它拉下来。

//create this field and property before the constructor
public int counter;
public int Counter
{
    get { return counter; }
    set { counter = value; }
}

//button click sets the interval to 1sec, starts timer and sets the int Counter to 0
private void button1_Click(object sender, EventArgs e)
{
    timer1.Interval = 1000;
    timer1.Start();
    Counter = 0;
}

//the tick event iterates the Counter property +1 everytime the timer advances 1sec and while Counter is under 5 for example it creates those objects
private void timer1_Tick(object sender, EventArgs e)
{
    Counter++;
    while (counter < 5)
    {
        DrawMap ortamcizdir = new DrawMap(p_box_map, bmp, ZoomControl, panel1);
        DrawCell hucrecizdir = new DrawCell (p_box_map, bmp, a, ZoomControl, ZoomKontrolBolen);
    }
}
