1            if (upload1.HasFile)//判断控件是否有文件路径
 2                 {
 3                     string filename = upload1.FileName;//取得文件名
 4                     filename = filename.Substring(filename.LastIndexOf(".") + 1);//取得后缀
 5                     if (filename.ToLower() == "jpg" || filename.ToLower() == "gif")//判断类型
 6                     {
 7                         string img = DateTime.Now.ToString("yyyyMMddHHmmssfff") + "." + filename;
 8                         upload1.SaveAs(Server.MapPath("images/") + img);
 9                         string picture = ("images/") + img;
10                         //传到根目录的images文件夹+重命名的文件名，也可以用原来的图片的名称，自己定。上传成功；
