Global variables in c#.net

Question

How can I set a global variable in a C# web application?

What I want to do is to set a variable on a page (master page maybe) and access this variable from any page.

Answer 1

/// 

/// Contains global variables for project.
/// 
public static class GlobalVar
{
/// 

/// Global variable that is constant.
/// 
public const string GlobalString = "Important Text";

/// 

/// Static value protected by access routine.
/// 
static int _globalValue;

/// 

/// Access routine for global variable.
/// 
public static int GlobalValue
{
get
{
    return _globalValue;
}
set
{
    _globalValue = value;
}
}

/// 

/// Global static field.
/// 
public static bool GlobalBoolean;
}
