Answer 1

public Image[] images = new Image[7];
public static int PicNow = 0; //当前图片索引
protected void Page_Load(object sender, EventArgs e)
{
for (int i = 0; i < 7; i++)
{
images[i] = new Image();
}
images[0].ImageUrl = "~/Resources/1.jpg";
images[1].ImageUrl = "~/Resources/2.jpg";
images[2].ImageUrl = "~/Resources/3.jpg";
images[3].ImageUrl = "~/Resources/4.jpg";
images[4].ImageUrl = "~/Resources/5.jpg";
images[5].ImageUrl = "~/Resources/6.jpg";
images[6].ImageUrl = "~/Resources/7.jpg";
this.LinkButton1.Enabled = false;
}
protected void LinkButton2_Click(object sender, EventArgs e)
{
if (PicNow == 5)
{
PicNow++;
this.Image1.ImageUrl = images[PicNow].ImageUrl;
this.LinkButton2.Enabled = false;
this.Label1.Text = "第" + (PicNow + 1).ToString() + "张";
}
else
{
PicNow++;
this.Image1.ImageUrl = images[PicNow].ImageUrl;
this.LinkButton1.Enabled = true;
this.Label1.Text = "第" + (PicNow + 1).ToString() + "张";
}
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
if (PicNow == 1)
{
PicNow--;
this.Image1.ImageUrl = images[PicNow].ImageUrl;
this.LinkButton1.Enabled = false;
this.Label1.Text = "第" + (PicNow + 1).ToString() + "张";
}
else
{
PicNow--;
this.Image1.ImageUrl = images[PicNow].ImageUrl;
this.LinkButton2.Enabled = true;
this.Label1.Text = "第" + (PicNow + 1).ToString() + "张";
}
}

使用ASPNETPAGER第三方翻页控件来实现，就可以了。
