public static MySingleton TheOnly
{
get { return theOneAndOnly; }
}
private MySingleton()
{

// remainder elided
}
The singleton pattern can just as easily be written this way, in case you
have more complicated logic to initialize the singleton:
public class MySingleton2
{
private static readonly MySingleton2 theOneAndOnly;
static MySingleton2()
{
theOneAndOnly = new MySingleton2 ();
}
public static MySingleton2 TheOnly
{
get { return theOneAndOnly; }
}
private MySingleton2()
{
}
// remainder elided
}
As with instance initializers, the static initializers are called before any static
constructors are called. And, yes, your static initializers execute before the
base class's static constructor.
The CLR calls your static constructor automatically before your type is
first accessed in an application space (an AppDomain). You can define only
