Singleton class in C#.Net



In this post we will discuss about Singleton class in C#.Net. Also you can check out my previous posts on:

- Identity in sql server 2008

- Upload multiple files in Asp.Net file upload control

- Post form data to 3rd party URL in Asp.Net

Singleton class allows only one instance. This is helpful if you want only one object of a class to perform operations.

Below is a way to implement:

using System;

public class Singleton
{
   private static Singleton instance;

   private Singleton() {}

   public static Singleton Instance
   {
      get
      {
         if (instance == null)
         {
            instance = new Singleton();
         }
         return instance;
      }
   }
}
