Detect request is a crawler/bot - asp.net

-
Sometimes you want to avoid bot from crawling the page with sensitive information like phone number and email address, so you need to have a method to detect either the request is a visitors or bot. 

This code snippet shows how you can determine the request is a crawler or not.

Code Behind 

   /// <summary>  
     /// Returns whether browsing device is search engine crawler (spider, bot).  
     /// </summary>      
     public bool IsCrawler()  
     {  
       if (HttpContext.Current != null)  
       {  
         HttpRequest currentRequest = HttpContext.Current.Request;  
         return (currentRequest.Browser != null) && currentRequest.Browser.Crawler;  
       }  
       return false;  
     }

You can put this method under a static class and call it from the Global.asax file.
