Hi,
If you're talking about Optical Character Recognition (OCR) there a few options. Microsoft has OCR capabilities built in to Office 2007 which you can make use as specified in this article on Using The Office 2007 OCR Component in C#. There are also many 3rd party APIs, such as the Aspose OCR Component.

For more options, just do a google search for "c#" "OCR".
or Check below Link

you would need to read about how OCR works and would come up with some algorithm for it.
It is not an easy task.

Else do find another API that helps do this

To extract text from image, it is recommended to use OCR control SDK.
