You need to add an empty static constructor, this way it's guaranteed to be lazy. Otherwise the instance will get created at some unspecified time between the program start and first access. (.NET runtime 2.0 is known to have more eager strategy, so you'll probably not get the lazy beh...
When working with OOP design and talking about Singleton types: the primary objective is that a Singleton is a type of Object that you will only ever need 1 instance of the object during the life of the program's or application's run time. What I typically do is I create a Singleton C...
Singleton design pattern in C# is one of the most popular design patterns. In this pattern, a class has only one instance in the program that provides a global point of access to it. In other words, a singleton is a class that allows only a single instance of itself to be created and...
In order to evaluate the impact of assisted reproductive technology (ART) procedure and individual factors on the sex ratio of singletons and twins at birth afterin vitrofertilization (IVF) and intra-cytoplasmic sperm injection (ICSI) treatment in China. We conducted a retrospective cohort study in...

It will give the correct result in the multi-threaded scenario, as shown below. Example: Copy public class Program { public static void Main() { var numbers = Enumerable.Range(0, 10); Parallel.ForEach(numbers, i => { VoteMachine.RegisterVote(); }); Console.WriteLine(VoteMachine.Total...
Test program; on first form you have two buttons, one which sets the amount of singleton, and second button which opens up another form which then sets the amount again. Once returned to the first form, the value updates to the one set on second form. ...
// This program illustrates how to write a singleton class (a class that // can have only one instance) in C++. The trick is to make the default // constructor, copy constructor and assignment operator all private. A // static function GetInstance returns the one and only object instance...
class Program { static void Main(string[] args) { double radiusOfCircle = 10.8; double lengthOfRectangle = 5.5; double widthOfRectangle = 2.3; double sideOfSquare = 4.0; double heightOfTriangle = 9.0; double baseOfTriangle = 5.0; WriteLine("Area of Rectangle with length {0...
This means they can’t use information known only once the program is up and running (for example, configuration loaded from a file). It also means they can’t reliably depend on each other — the compiler does not guarantee the order in which statics are initialized relative to each...
