Captcha Using ASP.Net

There is much technical logic to make captcha I am not expert and deep technical but I have tricks that make me able to make captcha. My logic is simple; Make some static image with alphanumeric character. You can change the text shape using photoshop. After creating image add image text into database with an id, generate random number and match it with database id field then fetch image text value and matched its value form user value provide by text box. Following images and code are example of my logic. Enjoy it !
