你这个用的是ImageButton,但是我没看到代码里触发FileUpload的代码？我想要的是点击这个按钮弹出文件选择框，选择完后加载并存储

 //点击上传按钮
    protected void Button1_Click(object sender, ImageClickEventArgs e)
    {
        string fileFullName = string.Empty;
        string fileFullNameS = string.Empty;
        string timgsrc = string.Empty;
        string fileName = DateTime.Now.ToFileTime().ToString();
        string exName = Path.GetExtension(this.FileUpload1.FileName);
        string filepath = Server.MapPath("~/imgApprove");
        string filename_s = "s_" + fileName;
        if (exName.ToLower().Equals(".jpg") || exName.ToLower().Equals(".gif") || exName.ToLower().Equals(".png"))
        {
            //限制大小
            if (FileUpload1.FileBytes.Length / (1024.00 * 1024.00) > 1) { message.InnerText = "您上传的图片(" + Math.Round(FileUpload1.FileBytes.Length / (1024.00 * 1024.00), 2) + "M)超过了1M,上传失败！"; return; }
            fileFullName = filepath + "//" + fileName + exName;
            this.FileUpload1.SaveAs(fileFullName);
            timgsrc = fileName + exName;
            // 生成缩略图方法
            fileFullNameS = filepath + "//" + filename_s + exName;
            Share.MakeThumbnail(fileFullName, fileFullNameS, 280, 210, "Cut");

           //显示图片
              Image.imageUrl="imgApprove/"+timgsrc ;
        }
        else
        {
            //Response.Write("<script>alert('图片格式不正确！');</script>");
            ClientScript.RegisterStartupScript(this.GetType(), "", "<script>sAlert('图片格式不正确！');</script>");
            return;
        }
