渲染部分为String的控制器或其他地方 [英] Render Partial to String in the Controller or elsewhere

问题描述

所以基本上我有一个可以建立一个很好的表，我的局部视图。我想每星期通过电子邮件发送此表到我的用户。而不必基本上再次复制的模板，我想我的模型转发给控制器，并获得相应产生的 HTML 为字符串。

So basically I have a partial view which can build a nice table for me. I would like to email this table out every week to my users. Instead of having to basically copy the template again, I would like to forward my model to the controller and receive the corresponding generated HTML as a String.

是否有可能在控制器做到这一点，我觉得这应该是pretty简单的过程。

Is it possible to do this in a Controller, I feel it should be a pretty simple process.

推荐答案

要把它放到辅助文件：

public static string RenderViewToString(ControllerContext context, string viewName, object model)
        {
            if (string.IsNullOrEmpty(viewName))
                viewName = context.RouteData.GetRequiredString("action");

            ViewDataDictionary viewData = new ViewDataDictionary(model);

            using (StringWriter sw = new StringWriter())
            {
                ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(context, viewName);
                ViewContext viewContext = new ViewContext(context, viewResult.View, viewData, new TempDataDictionary(), sw);
                viewResult.View.Render(viewContext, sw);

                return sw.GetStringBuilder().ToString();
            }
        }

然后再从该控制器可以称之为是这样的：

And then from the controller you can call it like this:

var order = orderService.GetOrder(id);

var orderPrint = MyHelper.RenderViewToString(this.ControllerContext, "_OrderView", order);
