如何在1个Windows服务中托管2个WCF服务？

using System.ServiceModel;
using System.ServiceModel.Description;
using System.ServiceProcess;

namespace WindowsServiceWithTwoWCFServices
{
    public partial class MyWindowsService : ServiceBase
    {
        private ServiceHost serviceHost1;
        private ServiceHost serviceHost2;

        public MyWindowsService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            // 创建 ServiceHost 实例
            serviceHost1 = new ServiceHost(typeof(Service1));
            serviceHost2 = new ServiceHost(typeof(Service2));

            // 添加服务终结点
            serviceHost1.AddServiceEndpoint(typeof(IService1), new BasicHttpBinding(), "http://localhost:8001/Service1");
            serviceHost2.AddServiceEndpoint(typeof(IService2), new BasicHttpBinding(), "http://localhost:8002/Service2");

            // 启动服务主机
            serviceHost1.Open();
            serviceHost2.Open();
        }

        protected override void OnStop()
        {
            // 关闭服务主机
            serviceHost1.Close();
            serviceHost2.Close();
        }
    }
}
