推荐答案

问题可能在于如何将图像加载到表中然后再加载到数据库中。

看看这里：为什么我得到参数无效。我从数据库中读取图像时出现异常？ [ ^ ]它解释了最常见的错误。如果查看数据库中的数据，您可能会看到它描述的字符串。

The problem is probably how you are loading the images into the table and then to the DB.
Have a look here: Why do I get a "Parameter is not valid." exception when I read an image from my database?[^] it explains the most common mistake. If you look at the data in your DB, you will probably see the string it describes.
