更改按钮的颜色很短的时间 [英] Change button color for a short time

问题描述

我想改变一个按钮的backgroundColor为几秒钟石灰，然后改回正常。出于某种原因，它只是不工作，我要等待那些秒钟，有些东西我还测试工作，但backgroundColor时没有改变。这是我到目前为止已经试过：

I would like to change the backgroundcolor of a button for a couple of seconds to lime and then change it back to normal. For some reason it simply doesnt work, I have to wait for those seconds and some things I tested also work but the backgroundcolor isn't changed. This is what I've tried so far:

private void button1_Click(object sender, EventArgs e)
{
    button1.BackColor = Color.Lime;
    Thread.Sleep(2000);
    button1.BackColor = SystemColors.Control;
}

希望有人可以帮我这个！

Hopefully someone can help me out with this!

推荐答案

您需要一个计时器。
从工具箱一个计时器添加到您的窗体。多布尔点击它添加一个计时器Tick事件处理程序

You need a timer. Add a Timer from Tool Box to your form. Doble click on it to add a timer tick event handler

    private void button1_Click(object sender, EventArgs e)
    {
        button1.BackColor = Color.Lime;
        //Set time between ticks in miliseconds.
        timer1.Tick=2000;
        //Start timer, your program continues execution normaly
        timer1.Start;
        //If you use sleep(2000) your program stop working for two seconds.

    }
        //this event will rise every time set in Tick (from start to stop)
        private void timer1_Tick(object sender, EventArgs e)
        {
          //When execution reach here, it meas 2 secons have past. Stop Timer and change color
          timer1.Stop;
          button1.BackColor = SystemColors.Control;
        }
