double check lock, basic question

private static object SyncRoot = new object();
private static object TheLazyOne = null;
 
public static object Instance{
  get{ 
    //The first caller will see TheLazyOne as null
    if (TheLazyOne == null)
    {
        //Before the first caller gets to create the instance, a second one snuck in behind it
        lock (SyncRoot)
        {
            //The first caller can create the new instance as it is still null
            if (TheLazyOne == null)
                TheLazyOne = new object();
            //The second caller waits at the lock until the first exists
            //A third caller will now be able to skip to the end
        }
        //The first caller exits and allows the second to try.  TheLazyOne is no longer null so it skips instantiation
    }
    //The first & second callers (as well as any future callers) all end up here to return the singleton
    return TheLazyOne;
  }
}

private static Lazy<object> TheLazyOne = new Lazy<object>();
public static object Instance{
  get{
    return TheLazyOne.Value;
  }
} </object></object>
