public - Makes the property public. static - Makes the property a static member. Modifiers for property accessors: private - Makes the accessor private. protected - Makes the accessor protected. public - Makes the accessor public. The default modifiers for the accessors are inherited from the property.
In C#, a static constructor is a static data initializer. [4]: 111–112 Static constructors are also called class constructors. Since the actual method generated has the name .cctor they are often also called "cctors". [5] [6] Static constructors allow complex static variable initialization. [7]
Initialization is distinct from (and preceded by) declaration, although the two can sometimes be conflated in practice. The complement of initialization is finalization, which is primarily used for objects, but not variables. Initialization is done either by statically embedding the value at compile time, or else by assignment at run time.
If the helper object is static (one per class loader), an alternative is the initialization-on-demand holder idiom [11] (See Listing 16.6 [12] from the previously cited text.) // Correct lazy initialization in Java class Foo { private static class HelperHolder { public static final Helper helper = new Helper (); } public static Helper getHelper ...

Resource acquisition is initialization (RAII) [1] is a programming idiom [2] used in several object-oriented, statically typed programming languages to describe a particular language behavior. In RAII, holding a resource is a class invariant , and is tied to object lifetime .

In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.
