title: Utility class or Common class in asp.net
body: <p>Do anyone knows about the class which has the common function which we generally use while developing web application. I have no idea what you may call it, it may be the utility class or common function class. Just for reference, this class can have some common function like:</p>
  
  <ol>
  <li>Generate Random number</li>
  <li>Get the file path</li>
  <li>Get the concatinated string</li>
  <li>To check the string null or empty</li>
  <li>Find controls</li>
  </ol>
  
  <p>The idea is to have the collection of function which we generally use while developing asp.net application.</p>
