ServiceStack 在 razor 页面中包含另一个 razor 页面

Question

我想在剃刀页面中包含类型化模型子页面。我知道SS和MVC剃刀不一样。实现的方法可能会有所不同。

到目前为止，这就是我所想出的（看起来很难看，我知道......）：

    //this is somewhere in your default.cshtml
    @{
        //grab your service from Ioc
        using(var service = Get<RockstarsService>()) {
            //execute the service to get a response
            var resp = service.Get(new Rockstars());
            //call the partial razor page Rockstar.cshtml
            <p>@Html.Partial("Rockstars",resp)</p>
            //or @Html.Partial("Rockstars") will do, seems like the resp is cached anyway 
            //or @Include("Rockstars",resp) will work, too.
        }
    }

此解决方案适用于类型化模型子页面，前提是该子页面不包含任何 html 帮助程序。

但是，如果子页面有 html 帮助程序，例如

@Html.Label("sometag") //PROBLEM HERE <---------------------

或者

@Html.TextBox("name","text") //PROBLEM HERE <---------------------

然后它会抛出服务器错误：

Server Error in '/' Application.
Could not execute partial: Rockstars, model: RazorRockstars.WebHost.RockstarsResponse

（Bloody VS Razor 断点不起作用，因为它是纯粹的 SS，而不是 MVC 项目。这让我很难查明问题......但那是另一个故事）

任何帮助都会很棒。

我真的认为你正在寻找渲染动作而不是你正在做的事情。
