title: How to generate customized user id?
body: <p>I'm working on a web application that is required to enable a multitude of users of various designations to log into a system. But unlike conventional method of generating user ids, I want to use certain parameters.</p>
  
  <p>Eg: <code>TECH12nameIND01</code></p>
  
  <p>Here the example I've mentioned above contains</p>
  
  <ul>
  <li>designation</li>
  <li>year of join</li>
  <li>name of the emp</li>
  <li>location</li>
  <li>auto increment number</li>
  </ul>
  
  <p>The <code>user id</code> should appear in my registration page at the end of registering.</p>
  
  <p>I seek the <code>C#</code> code for this particular issue.</p>
