C＃如何按顺序显示图像列表中的图像。 [英] C# how to display images from an imagelist in a sequential order.

问题描述

为了清晰起见，我正在修改我之前发布的问题。我正在尝试编写一个代码，每隔两秒显示一个新图像。我编写了一个代码，可以从图像列表中随机获取图像并显示它们。但是，我需要它按顺序排列。做这个的最好方式是什么？



Ps。你可以告诉我，我是这个网站的新手，所以我为任何格式错误道歉。



我尝试过：

I am editing my previously posted question for clarity. I am trying to write a code where a new image is displayed every two seconds. I have written a code that randomly takes images from an imagelist and displays them. However, I need it to be in a sequential order. What is the best way to do this?

Ps. as you can probably tell, I am new to this site so I apologize for any formatting errors.

What I have tried:

private void timer1_Tick(object sender, EventArgs e)
        {
            Random mySchool;
            mySchool = new Random();  
            picCompanies.Image = this.imageList1.Images[mySchool.Next(4)]; 
        }

推荐答案

您使用与随机数相同的方式进行操作，现在只使用自己的每次使用时递增的数字（列表中必须至少有1个图像，或者您必须添加更多错误检查）：

You do it in the same way as with a random number, only now you use your 'own' number that is incremented each time it is used (there has to be at least 1 image in the list or you have to add more error checking):

private int myNumber = 0;

private void timer1_Tick(object sender, EventArgs e)
{
    picCompanies.Image = this.imageList1.Images[myNumber];
    myNumber = myNumber + 1;
    if (myNumber >= imageList1.Images.Count) myNumber = 0;
}
