问题
I have some images stored in varbinary fields. I want get them into a List object e.g List list
From here I can access each image byte array, e.g image.ImageData.
I need to bind them somehow as thumbnails to asp:gridview or something similar, is it possible with binary/byte[] images?
回答1:
I would try a slightly different approach.
Use an HTTPHandler to retrieve the images and bind the image src to the handler
Embed something like this in your gridview:
<img src="http://www.yoursite.com/imageHandler.ashx?id=4" />
See this StackOverflow answer for how to write the handler: Create PNG image with C# HttpHandler webservice
