Implementing Thread Safe Singleton Pattern in C#

Hi today I want to share Thread Safe Singleton code sample. I found this samples from Here You can use Singleton_Lazy class if you are using .net framework 4.0+

namespace Patterns
{
    
    public class Singleton
    {
        private static readonly Singleton instance = new Singleton();

        //Empty for laziness
        static Singleton() { }

        private Singleton() {

            Console.WriteLine("CCTOR");
        }

        public static Singleton Instance { get { return instance; } }

        public void DoSomeThing()
        {
            Console.WriteLine("DoSomeThing");
        }
    }




    public sealed class Singleton_Lazy
    {
        private static readonly Lazy<Singleton_Lazy> lazy =
            new Lazy<Singleton_Lazy>(() => new Singleton_Lazy(),true);

        public static Singleton_Lazy Instance { get { return lazy.Value; } }

        private Singleton_Lazy()
        {
            Console.WriteLine("CCTOR");
        }

        public void DoSomeThing()
        {
            Console.WriteLine("DoSomeThing");
        }
    }
}
