推荐答案

你可以用一个计时器来达到这个目的。

You could use a timer to achieve this.

using System;
using System.Windows.Forms;

namespace WindowsFormsApplicationImageHide
{
    public partial class Form1 : Form
    {
        System.Timers.Timer timer;

        public Form1()
        {
            timer = new System.Timers.Timer(5000);
            timer.Elapsed += timer_Elapsed;

            InitializeComponent();
        }

        void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            pictureBox1.Visible = false;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            pictureBox1.Visible = true;

            timer.Start();
        }
    }
}

当您按下按钮时，包含图像的图片框

变得可见，计时器启动。

5000毫秒后，计时器过去，图片框变得不可见。

When you press the button the picture box containing an image
becomes visible and the timer is started.
After 5000 ms the timer elapses and the picture box becomes invisible.

你可以使用计时器 [ ^ ]将计时器设置为5秒的类，然后可以删除，删除或隐藏控件。

You can use the timer[^] class to set a timer for 5 seconds, and after that you can delete, remove, or hide the control.

Timer timer = new Timer(5000); // 5000ms = 5s
timer.Elapsed += Timer_Elapsed;
timer.Enabled = true;

// create the functions
static void Timer_Elapse(object sender, ElapsedEventArgs e)
{
    // Handle the event and hide the image
}

确保在显示图像时启动计时器;所以5秒后它将被删除（隐藏）。

Make sure you start the timer when you show the image; so after 5 seconds it will be removed (hidden).
