在后台获取PartialView生成的字符串，可以通过如下方法进行获取生成。

代码：

 public static string RenderPartialView(ControllerContext controllerContext, ViewDataDictionary viewData,TempDataDictionary tempData, string viewName, object model){if (string.IsNullOrEmpty(viewName)){viewName = controllerContext.RouteData.GetRequiredString("action");}viewData.Model = model;using (var stringWriter = new StringWriter()){ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controllerContext, viewName);var viewContext = new ViewContext(controllerContext, viewResult.View, viewData, tempData, stringWriter);viewResult.View.Render(viewContext, stringWriter);var result=  stringWriter.GetStringBuilder().ToString();return result;}}

调用：

 public ActionResult Data(string type){var model = new Model();model.List = QueryEntry.GetHistory(type);var viewHtml = HtmlRender.RenderPartialView(ControllerContext,ViewData, TempData, "~/Views/History/Data.cshtml", model);return Json(new { viewHtml });}
