title: ASP.NET search application variables whose name starts with "xxx"
body: <p>I'mcreating a turn game ASP.NET based site where some players can start a game and other will simply join that game.</p>
  
  <p>In order to manage each game I will create an application level variable with a set prefix, say "game_". And each game will bear a random game ID.</p>
  
  <p>So there will be a bunch of variables like game_1234, game_56789, game_nnnn...</p>
  
  <p>Question is: how can I retrieve all the <strong>game_*</strong> variables to look into their content and perform changes / remove some of them?</p>
  
  <p>Edit: variables are stored with this code where gameID has been set at random:</p>
  
  <pre><code>HttpContext.Current.Application("game_" &amp; gameID) = some_value 
  </code></pre>
