The image control displays binary images.

The image control can only set images through the image. imageurl attribute. The image object is not displayed. When the data we read is binary or an image object, we need to add a secondary page for display.

Secondary pageCode

 
Public partial class picture: system. web. UI. page {protected void page_load (Object sender, eventargs e) {string = "select * From 'table name 'where' condition '"; datatable dt = new datatable (); string connstr = 'Connection string'; Conn = new oracleconnection (connstr); cmd = new oraclecommand (strsql, getconn (); cmd. commandtype = commandtype. text; using (SDR = cmd. executereader (commandbehavior. closeconnection) {DT. load (SDR);} If ( DT. Rows. Count! = 0) {response. binarywrite (dt [I] [J]) ;}}
