ImageButton如何保存ImageButton图像 [英] ImageButton how to save ImageButton image

问题描述

希望我能在这里得到一些帮助 - 我正在尝试将ImageButton图像保存到我的数据库中。基本上，获取imagebutton图像/值并将其转换为byte []并将字节保存到数据库。我知道如何将字节保存到数据库，但不知道如何将imagebutton图像/对象转换为字节。我已经尝试了一切，但没有运气。

解决方案

对不起，用户可以动态更改ImageButton图像;当发生这种情况时，我想从ImageButton捕获新图像并将其保存到数据库中。我不知道他们在本地计算机上从哪里上传文件

图像在你的服务器上开始，所以你为什么要这样做呢？
