title: ASP.NET: variable that can be accessed by entire site
body: <p>I am new to ASP .NET, I am trying to setup a website in Visual Studio with C#.</p>
  
  <p>My background is in PHP.  In that language, if I want a variable to be accessible by every page, simply put it in a include file.  </p>
  
  <p>Is there anything similar to C# and ASP .NET?  There is an site.master page, but I am not sure how to access it's variables from page contents.  Thanks in advance.</p>
