SMS Spam detection using c# in Windows Form

Hi, thank you for your response. I would like to do the SMS spam detection in Winforms by comparing the keywords. For instance, in my datasets, there is a lot of spam word such as "Click", "Free", "Get" and "link".. when users enter their message, the system will detect the word such as "Click" and "Get" from the database. That's how the system will detect the message is a spam. I'm using .Net framework.
