如何用C#里面的winform窗体内的标签通过上一页和下一页的按钮进行切换？

Question

本人小白，现在做一个软件，需要26个英文字母播放，但是，如果做成图片插入的话，文件总的加起来有点大，所以想用标签来回切换播放字母，另外，上一页和下一页怎么写？用图片有教程，可以做，但是用标签，我不会，百度了一天也没百度出来，请问大神，该怎么写？

Answer 1

String[] Contents = { "a", "b" ,"c","d","e", "f" ,"g","h", "i" ,"j","k", "l" ,"m","n", "o" ,"p","q", "r" ,"s" ,"t", "u" ,"v"，"w", "x" ,"y","z"};//存入26个字母
int currentIndex = 0;//设置初始显示为字母a
假设标签名字为LabelContent，在属性中设置其初值Text为a

上一页按钮假如设为BtnPrevious，其响应事件：

 private void BtnPrevious_Click(object sender, EventArgs e)
        {

            currentIndex -= 1;
            if (currentIndex < 0)
            {
                LabelContent.Text = Contents.GetValue(25).ToString();
                currentIndex = 25;
            }
            else
                LabelContent.Text = Contents.GetValue(currentIndex).ToString();
        }

下一页按钮假定为 BtnNext，其响应函数为

 private void BtnNext_Click(object sender, EventArgs e)
        {

            currentIndex += 1;
            if (currentIndex > 25)
            {
                LabelContent.Text = Contents.GetValue(0).ToString();
                currentIndex = 0;
            }
            else
                LabelContent.Text = Contents.GetValue(currentIndex ).ToString();
        }
