把视图转换为字符串

把部分视图转换为html字符串，你可以参考下面的方法：

 

 public static string RenderPartialViewToString(Controller controller, string viewName, object model)
        {
            controller.ViewData.Model = model;
            try
            {
                using (StringWriter sw = new StringWriter())
                {
                    ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, viewName);
                    ViewContext viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
                    viewResult.View.Render(viewContext, sw);

                    return sw.GetStringBuilder().ToString();
                }
            }
            catch (Exception ex)
            {
                return ex.ToString();
            }
        }
