Unity Application Block,如何将参数传递给Injection Factory？

using Microsoft.Practices.Unity;

// 定义一个接口
public interface IMyService
{
    void DoSomething(string parameter);
}

// 实现接口的类
public class MyService : IMyService
{
    private string _parameter;

    public MyService(string parameter)
    {
        _parameter = parameter;
    }

    public void DoSomething(string parameter)
    {
        Console.WriteLine("Parameter: " + _parameter);
    }
}

// 在Unity容器中注册接口和实现类
var container = new UnityContainer();
container.RegisterType<IMyService, MyService>();

// 注册Injection Factory
container.RegisterType<IMyService>(new InjectionFactory(c =>
{
    var parameter = "Hello, World!";
    return new MyService(parameter);
}));

// 解析对象并调用方法
var myService = container.Resolve<IMyService>();
myService.DoSomething();
