                Text="Upload" CssClass="textbox" style="cursor:hand" 
                onclick="Button_Uploadfile_Click" /> 
后台：
//没文件夹创建文件夹
 public void FolderPath(string pathStr)
    {
        if (!Directory.Exists(pathStr))
        {
            Directory.CreateDirectory(pathStr);
        }
    }
//按钮触发
 protected void Button_Uploadfile_Click(object sender, EventArgs e)
    {
        string ServerPath = System.Web.HttpContext.Current.Request.MapPath（"upload/"+DateTime.Now.ToString("yyyyMMdd"));
        if (!string.IsNullOrEmpty(this.FileUpload_Upload.PostedFile.FileName))
        {
            FolderPath(ServerPath);
 string Sion = Path.GetExtension(this.FileUpload_Upload.FileName);
            string file = Path.GetFileNameWithoutExtension(this.FileUpload_Upload.FileName);
            string FileName =file+ DateTime.Now.ToString("yyyyMMddHHmmssFFFFF")+Sion;
            this.FileUpload_Upload.PostedFile.SaveAs(ServerPath + "/" + FileName );
            //Alert("Upload success");
            
        }
        else { 
//Alert("Please Select File To Upload!");
 }

                string timeStamp = DateTime.Now.ToString("yyyyMM");
                string path = Server.MapPath("/uploadfile/" + timeStamp);
                if (!Directory.Exists(path))
                    Directory.CreateDirectory(path);

Answer 4

string usename = users[0].CUserName.ToString();              //获取用户名
            string randomName = DateTime.Now.ToFileTime().ToString();   //系统当前时间为图片名称
            //string path = Request.MapPath("~/Content/images");    
            HttpPostedFileBase file = Request.Files["fileToUpload"];//获取页面上获取图片内容["fileToUpload"] 是页面上上传图片空间的name
            string pictureName = file.FileName;//上传图片的原名
            string extensionName = System.IO.Path.GetExtension(pictureName);//获取扩展名
            int randomcode = BaseRandom.GetRandom(1000, 9999);                //产生随机数
            string newName = string.IsNullOrEmpty(pictureName.Trim()) ? "" : usename + randomcode + randomName + System.IO.Path.GetExtension(pictureName);                                                                //重命名图片
                string savePath = HttpContext.Server.MapPath("~/Content/Uploads/img/" + usename);  //原图图片保存位置
                if (!System.IO.Directory.Exists(savePath))
                {
                    //如果路径不存在创建新文件夹
                    System.IO.Directory.CreateDirectory(savePath);
                }
                file.SaveAs(savePath +'/'+newName);                                                                           //将上传的文件保存到指定的目录。
                 ViewData["messageBox"] = "上传成功";
ps:这算是很完整的了
