求问模式达人，静态类可否代替单件？

哈哈哈~看代码：）想必单件模式大家都非常熟悉：）

namespace Singleton1
{
class Program
{
static void Main(string[] args)
{
for (int i = 0; i < 10; i++)
{
Factory.RecordCount();
}

Factory.Display();

global::System.Console.Read();
}
}

static class Factory
{
private static object objLock = typeof(Factory);
private static long longCount = 0;

public static void RecordCount()
{
lock (objLock)
{
longCount++;
}
}

public static void Display()
{
lock (objLock)
{
global::System.Console.WriteLine(longCount);
}
}
}
}
