如何使用c＃从asp.net中的数据库绑定图像？

Question

Answer 1

Suppose that you have data in imageData byte array

byte[] imageData=...;

You need to convert it into base64 as follows

string imageBase64 = Convert.ToBase64String(imageData);
string imageSrc = string.Format("data:image/gif;base64,{0}", imageBase64);

An in your page you can use

<img src= "<%= ImageSrcBytes %>" />

Note that it will not work in lower end browser.

For those browsers you need to save image in local folder and then provide the url for that image.

Or you can create a handler and call that handler as image source.
