Read the Niwalker's Singleton design mode to see the importance of the developer. Net framework feature is very surprised. The following is a single sample mode implementation code in the article: Public Sealed Class Singleton {Private Singleton (); Public static readonly singleton instance = new singleton ();} I also use .NET mixed for two years, although many programs and code have also been written, but I feel that the awareness of .NET Framework is only in the stage of use, it seems need Re-system replenishment class.
