ServiceStack Funq MVC html helper扩展

Question

我正在尝试创建一个MVC html helper扩展，它必须声明为静态类，如下所示：

public static class PhotoExtension
{
    public static IPhotoService PhotoService { get; set; }
    public static IGalleryService GalleryService { get; set; }

    public static MvcHtmlString Photo(this HtmlHelper helper, int photoId, string typeName)
    {
         //[LOGIC GOES HERE]
         return new MvcHtmlString(..some resulting Html...);
    }
}

现在，我想在Photo()方法中使用IPhotoService和IGalleryService。到目前为止，我发现如何在AppHost.Configure()中注入这些服务的唯一方法：

PhotoExtension.PhotoService = container.Resolve<IPhotoService>();
PhotoExtension.GalleryService = container.Resolve<IGalleryService>();

这是有效的，尽管我好奇是否有更好的方法来实现这一点。

IPhotoService和IGalleryService都是在AppHost.Configure()中以标准方式注册的。

谢谢，安东宁

更容易阅读/遵循，将它们连接到静态构造函数中？

using ServiceStack.WebHost.Endpoints;

public static class PhotoExtension
{
    public static IPhotoService PhotoService { get; set; }
    public static IGalleryService GalleryService { get; set; }

    static PhotoExtension()
    {
        PhotoService = EndpointHost.AppHost.TryResolve<IPhotoService>();
        GalleryService  = EndpointHost.AppHost.TryResolve<IGalleryService>();
    }

    public static MvcHtmlString Photo(this HtmlHelper helper, int photoId, string typeName)
    {
     //[LOGIC GOES HERE]
     return new MvcHtmlString(..some resulting Html...);
    }
}
