Question

在asp.net中用imgae控件显示图片五张图片中的随机一张

我只会两张图片的随机显示：
protected void Page_Load(object sender, EventArgs e)
{
Random rndGen = new Random();
int rndNum = rndGen.Next(10);
if (rndNum < 5)
imgBooks.ImageUrl = "~/images/Image1.jpg";
else
imgBooks.ImageUrl = "~/images/Image3.jpg";
}
是在cs里的代码，哪位大侠会五张图片随机显示的帮帮忙 写一下代码 谢谢

Answer 1

protected void Page_Load(object sender, EventArgs e)
{
Random rndGen = new Random();
int rndNum = rndGen.Next(10);
if (rndNum >0 && rndNum <= 5){
imgBooks.ImageUrl = "~/images/Image“+rndNum +".jpg";
}

Answer 2

switch((int)rnNum.Next(10))
{
case 0:
case 1:
imgBooks.ImageUrl="~/image/Image1.jpg";
break;
case 2:
case 3:
imageBooks.ImageUrl="~/image/Image2.jpg";
break;
....
case 8:
case 9:
imageBooks.ImageUrl="~/image/Image5.jpg";
break;
}
