public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("Load");
}
protected void Button1_Click(object sender, EventArgs e)
{
Image1.ImageUrl = Server.Mappath("~/show_files/dh_1.jpg");
}
}
提示信息是当前上下文中不存在Image1,提示我的确添加了Image1这个控件
目标是将控件的URL改成~/show_files/dh_1.jpg，原来Image1 的属性是~/show_files/dh_2.jpg

你可以动态改变图片名称，或者将图片的路径及名称存入一个库里，然动态改变就行了
