C# ASP.NET - a variable that's accessible from any function, and is different to any user? -

I need a variable that is available from any function in my code, but it is different for all users.

So I wrote:

  public class classedelcappero {personal string frasehiragana = String.Empty; Outer public strings {back to frasiragana; } Set {frasehiragana = value; }}}  

And then I put it in my function:

  protected zero page_load (object sender, event date e) {classedelcappero chepalle = new classedelcappero (); String frasiragna = chapli .hurgana; }  

and it works ... but if I access it from some other function, such as

  protected zero button reperovascular (object sender , EventAgds E)  

The value is empty ... Is this OK?

What to do? Use session variables?
