推荐答案

可能不是那个代码 - 看起来很好 - 但你保存的方式数据到您的数据库。



看看这个：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？ [ ^ ] - 它的代码在C＃中不是VB，但它非常清晰，非常非常适用！

The chances are that it's not that code - which looks fine - but the way you save the data to your DB instead.

Have a look at this: Why do I get a "Parameter is not valid." exception when I read an image from my database?[^] - it's code is in C# not VB, but it is pretty clear, and very, very applicable!
