如何从一个单独的类打开/运行一个类

我在Xamarin Studio上用c#制作一个简单的DOS操作系统。问题是，我在Visual Studio中编写了几个程序来做我在Xamarin上做不到的事情。

尽我所能解释我的困难:我有一个名为OSBootup.cs的类，我想让这个类运行，然后它在我的项目中启动了一个不同的类。有什么办法吗?如果不行，还有什么别的方法吗?

我的代码:(osboot .cs)

using System;
using System.IO;
using System.Threading;
namespace OperatingSystemCore
{
    public static class OSBootup
    {
        public static void Main (String[] args)
        {
            bool isStarting;
            Start:
            isStarting = true;
            Console.Write ("Starting SyteraOS ");
            Thread.Sleep (1000);
            Console.Write (". ");
            Thread.Sleep (1000);
            Console.Write (". ");
            Thread.Sleep (1000);
            Console.Write (". ");
            Thread.Sleep (1000);
            Console.Clear ();
            Console.Write ("Starting SyteraOS ");
            Thread.Sleep (1000);
            Console.Write (". ");
            Thread.Sleep (1000);
            Console.Write (". ");
            Thread.Sleep (1000);
            Console.Write (". ");
            Thread.Sleep (4500);
            Console.Clear ();
            Console.WriteLine ("Press Any Key To Start SyteraOS ...");
            Console.ReadKey ();
            End:
            DOSConsole DConsole = new DOSConsole ();
            isStarting = false;
        }
    }
}

如果你需要看我的另一个文件，(DOSConsole.cs):

using System;
namespace OperatingSystemCore
{
    public class DOSConsole
    {
        public void Start ()
        {
            Console.WriteLine ("Give us a name.");
            Console.WriteLine ("");
            Console.Write ("Name: ");
            string Name = Console.ReadLine ();
            Console.Clear ();
            Console.Write ("User->" + Name);
        }
        public void Update ()
        {
        }
        public void Commands ()
        {
        }
    }
}
