如何图片轮换实现（加贴）

Question

8个图片，比如初始化8张图片分别是刘1，张2，李3，王4....... 当点击开始，启动一个Timer，这时轮流撤换刘1变成图A，其他不变，接着张2变成A,刘1变回刘1，其他不变，一直下去，直到用户点停止，timer.enalbe=false,轮到那里，那张图片就是A.在imer1_Tick中写如下代码：
PictureBox2.Image = this.ImageList1.Images [0];
PictureBox2.Image = WindowsApplication2.Properties.Resources.刘1;
PictureBox4.Image = this.ImageList1.Images[0];
PictureBox4.Image = WindowsApplication2.Properties.Resources.张2;代码是可以实现，但图片的转换没能在用户端表现，图片不能轮换！

Answer 1

设一个全程变量p＝0；timer1——Tick中switch（p）case 0：
PictureBox0.Image = this.ImageList1.ImagesA; 
PictureBox7.Image = WindowsApplication2.Properties.Resources.X7; case 1：
PictureBox1.Image = this.ImageList1.ImagesA; 
PictureBox0.Image = WindowsApplication2.Properties.Resources.刘1;case 2：
PictureBox2.Image = this.ImageList1.ImagesA; 
PictureBox1.Image = WindowsApplication2.Properties.Resources.张2;.。。 最后
p＋＋；
（if p==8) p=0;

Answer 2

这个代码可以在本地实现？
你可以增加一变量，每次执行timer1_Tick时，该变量变化。
该变量的不同值对应不同的图片。
把你的代码修改下即可

Answer 3

private int flat =0; 
switch (flat)
            {
                case 0:
                  
                        PictureBox2.Image = this.ImageList1.Images[0];                        PictureBox2.Image = WindowsApplication2.Properties.Resources.作废1;
                        break;
                    
                case 1:
                    
                        PictureBox4.Image = this.ImageList1.Images[0];
                        PictureBox4.Image = WindowsApplication2.Properties.Resources.撤消;
                        break;
                case 2:                        PictureBox5.Image = this.ImageList1.Images[0];
                        PictureBox5.Image = WindowsApplication2.Properties.Resources.撤消;
                        break;
                case 3:                        PictureBox8.Image = this.ImageList1.Images[0];
                        PictureBox8.Image = WindowsApplication2.Properties.Resources.撤消;
                        break;
                default:    
                    flat++;
                    if (flat == 8)
                    {
                        flat = 0;
                    }
                    break;
                                        
            }
上面代码执行后，图片不轮换。

Answer 4

        private void button1_Click(object sender, EventArgs e)
        {
            timer1.Enabled = !timer1.Enabled;
        }        int index = 1;        private void timer1_Tick(object sender, EventArgs e)
        {
            PictureBox pb = this.Controls["pictureBox" + index] as PictureBox;
            if (pb != null)
                pb.Image = imageList1.Images[0];
            switch (index)
            {
                case 1:
                    pictureBox8.Image = WindowsFormsApplication1.Properties.Resources.最后一张;
                    break;
                case 2:
                    pictureBox1.Image = WindowsFormsApplication1.Properties.Resources.第一张;
                    break;
                case 3:
                    pictureBox2.Image = WindowsFormsApplication1.Properties.Resources.第2张;
                    break;
                case 4:
                    pictureBox3.Image = WindowsFormsApplication1.Properties.Resources.第3张;
                    break;
                case 5:
                    pictureBox4.Image = WindowsFormsApplication1.Properties.Resources.第4张;
                    break;
                case 6:
                    pictureBox5.Image = WindowsFormsApplication1.Properties.Resources.第5张;
                    break;
                case 7:
                    pictureBox6.Image = WindowsFormsApplication1.Properties.Resources.第6张;
                    break;
                case 8:
                    pictureBox7.Image = WindowsFormsApplication1.Properties.Resources.第7张;
                    break;
            }
            index++;
            if (index > 8)
                index = 1;
        }

Answer 5

int i = 0;
在timer_click事件里:
i++
if(i % 8 == 0)
{
    轮换到第一张;
}
else if(i % 8 == 1)
{
    轮换到第二张;
}
......
else if(i % 8 == 7)
{
    轮换到第八张;
}

Answer 6

tks ojlovecd！
现在有一疑问，每个pictureBox都有轮转限制次数。如pictureBox8最多可以轮转3次，第一次轮转结束选择到pictureBox8 ，第三次和第5次也选到pictureBox8，那么以后的轮转，pictureBox8就不能参加轮转啦!

Answer 7

水平有限，有很多不完善的地方，你就当参考吧，自己再改改        private void button1_Click(object sender, EventArgs e)
        {
            int count = 0;
            foreach (int i in pollingCount)
                if (i == 0)
                    count++;
            if (count == 8)
                return;
            timer1.Enabled = !timer1.Enabled;
            if (!timer1.Enabled)
            {
                int i;
                if (index == 1)
                    i = 7;
                else
                    i = index - 2;
                if (pollingCount[index - 1] > 0)
                    pollingCount[index - 1]--;
                MessageBox.Show(index.ToString());
            }
            else
            {
                PictureBox pb = this.Controls["pictureBox" + (index == 1 ? 8 : index - 1)] as PictureBox;
                if (pollingCount[index - 1] == 0 && pb != null)
                    pb.Visible = false;
