copied!<p>This turned out more interessting than I thought initially:</p> <p>So the best solution would be</p> <pre><code>public sealed class Singleton { private static readonly Singletion _instance = new Singleton(); private Singleton() { //do your construction } public static Singleton getInstance() { return _instance; } } </code></pre> <p>From my current understanding the programming environment (Java, .NET) should not matter for this solution.</p> <p>Any thoughts or comments?</p> <p>Further reading I have dug out:</p> <ul> <li>MSDN on Singletons:<a href="http://msdn.microsoft.com/de-de/library/ms998558.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/de-de/library/ms998558.aspx</a></li> <li>MSDN on static members: <a href="http://msdn.microsoft.com/en-us/library/79b3xss3.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/79b3xss3.aspx</a> Especially referring to <blockquote> <p>Static members are initialized before the static member is accessed for the first time and before the static constructor, if there is one, is called.</p> </blockquote></li> </ul> <p>Edit: As for Java it should also work:</p> <ul> <li>But it will not be lazy, the Singleton will be constructed once the class is loaded</li> <li>See also: Section 8.3.1.1 of <a href="http://java.sun.com/docs/books/jls/third_edition/html/classes.html" rel="nofollow noreferrer">http://java.sun.com/docs/books/jls/third_edition/html/classes.html</a></li> <li>See <a href="http://java.sun.com/docs/books/jls/third_edition/html/execution.html#44557" rel="nofollow noreferrer">http://java.sun.com/docs/books/jls/third_edition/html/execution.html#44557</a></li> </ul> <p>Now if someone points out a save C++ version it would be complete... (I away from C++ too long to remember the details...)</p>
