Question

我正在使用Orchard 1.6并希望将视图渲染为具有主题自定义布局的字符串等等。

实际上有orchard cms rendering shape as email template但是我需要更多细节（不能添加对该答案的评论，我没有足够的代表:(并且无法发送私信）

我在控制器中进行测试（将来我想在单独的任务中执行int）。所以控制器是（模型是具有一些属性的简单类）

var renderer = new ViewRenderer(
    _workContextAccessor,
    _siteThemeService,
    _services);

var shape = ShapeFactory.MyTestShape(Model: model);
var result = renderer.RenderMessage(shape);

渲染器

public string RenderMessage(dynamic shape)
{
    var httpContext = new ViewRendererHttpContext(new Uri("http://localhost/orchard/"));
    var routeData = new RouteData();
    routeData.DataTokens.Add("IWorkContextAccessor", _workContextAccessor);
    routeData.Values["controller"] = "Dummy";
    var requestContext = new RequestContext(httpContext, routeData);
    var controllerContext = new ControllerContext(requestContext, new DummyController());

    var viewContext = new ViewContext(controllerContext, new ShapeView(shape), new ViewDataDictionary(shape.Model), new TempDataDictionary(), new StringWriter());
    var scope = _workContextAccessor.CreateWorkContextScope(viewContext.HttpContext);
    scope.WorkContext.CurrentTheme = _siteThemeService.GetSiteTheme();
    var page = new ViewRendererWebViewPage(viewContext, new ViewDataDictionary<dynamic>(shape.Model));

    var displayHelperFactory = _services.WorkContext.Resolve<IDisplayHelperFactory>();
    var display = displayHelperFactory.CreateHelper(page.ViewContext, page);
    var data = display(shape).ToHtmlString();
    scope.Dispose();

    return data;
}

ViewRendererHttpContext刚刚从HttpContextBase派生而且非常简单（可以发布其代码），DummyController是从Controller派生的空类，ShapeView是从IView派生的epmty类。

我的模块中有View / MyTestShape.cshtml。

问题在于深入执行var data = display(shape).ToHtmlString();时 var result = htmlHelper.Partial(harvestShapeInfo.TemplateVirtualPath, displayContext.Value);（类“ShapeTemplateBindingStrategy”，方法“private IHtmlString Render（......）”）我有例外“方法或操作没有实现。”

我应该采用什么方法和类？

感谢您的任何提示。我的英语很糟糕，很抱歉。

它也不适用于我，我正在使用Orchard 1.6。曾经有过投票让它发挥作用，但我不确定它是否在Orchard 1.7中被采用。

这是我在项目中执行此操作的方法（我将形状渲染为ajax DataTables的字符串），前提是您从控制器进行调用。

在您的服务（或控制器）内，您可以使用2种服务：IThemeAwareViewEngine和IDisplayHelperFactory：

    private readonly IThemeAwareViewEngine _themeAwareViewEngine;
    private readonly IDisplayHelperFactory _displayHelperFactory;
    public AjaxDataTables(
        IThemeAwareViewEngine themeAwareViewEngine,
        IDisplayHelperFactory displayHelperFactory
        )
    {
        _themeAwareViewEngine = themeAwareViewEngine;
        _displayHelperFactory = displayHelperFactory;
    }

如果您有对真实控制器的引用，这是获得魔术显示的方法：

    dynamic GetDisplayHelper(Controller controller)
    {
        // We can specify any view name, just to get a View only, the shape template finding will be taken care by DisplayHelperFactory.
        // Here the "Brandking" view is always existed, we can also use something like "Layout" ...
        var viewResult = _themeAwareViewEngine.FindPartialView(controller.ControllerContext, "Branding", false, false);
        var viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, new StringWriter());
        return _displayHelperFactory.CreateHelper(viewContext, new ViewDataContainer());
    }
    private class ViewDataContainer : IViewDataContainer
    {
        public ViewDataDictionary ViewData { get; set; }
    }

将形状渲染为字符串：

var display = GetDisplayHelper(controller);
var str = Convert.ToString(display(shape.Content));

同样，只有在您通过控制器操作进行调用时才能正常工作。

如何将形状渲染为字符串？
