==== C# static constructor ====
In [[C Sharp (programming language)|C#]], a ''static constructor'' is a static data initializer.<ref name=Albahari>{{cite book |last=Albahari |first=Joseph |title= C# 10 in a Nutshell |publisher= O'Reilly |isbn= 978-1-098-12195-2}}</ref>{{rp|111-112}} Static constructors are also called ''class constructors''. Since the actual method generated has the name ''.cctor'' they are often also called "cctors".<ref>{{cite web|url=http://ericlippert.com/2013/02/06/static-constructors-part-one/ |title=Fabulous Adventures in Coding |publisher=Eric Lippert |date=2013-02-06|access-date=2014-04-05}}</ref><ref>{{cite book|url=https://books.google.com/books?id=oAcCRKd6EZgC&pg=PA222 |title=Expert .NET 2.0 IL Assembler |publisher=APress |date=2006-01-01|isbn=9781430202233 |access-date=2014-04-05}}</ref>
Static constructors allow complex static variable initialization.<ref>[http://msdn.microsoft.com/en-us/library/k9x6w0hc%28VS.80%29.aspx Static Constructor in C# on MSDN]</ref>
Static constructors are called implicitly when the class is first accessed. Any call to a class (static or constructor call), triggers the static constructor execution.
Static constructors are [[thread safe]] and implement a [[singleton pattern]]. When used in a [[generic programming]] class, static constructors are called at every new generic instantiation one per type.<ref name=Skeet>{{cite book |last=Skeet|first=Jon|title= C# in Depth |publisher= Manning |isbn= 978-1617294532}}</ref>{{rp|38}}<ref name=Albahari>{{cite book |last=Albahari |first=Joseph |title= C# 10 in a Nutshell |publisher= O'Reilly |isbn= 978-1-098-12195-2}}</ref>{{rp|111}} Static variables are instantiated as well.
