asp.net mvc5 cs代码中获取视图生成后的HTML

Question

asp.netmvc

Answer 1

通过controller访问，处理后在form里提交到另一个controller

Answer 2

搜索一下：MVC  Filter（过滤器）

Answer 3

View 是在最后展示的，直接来是做不到的吧，需要View执行完以后才能知道生成的html是什么样子的，
所以需要2个控制器  
Controller1 ---->view展示完毕----->触发Controller2 这时候就知道Html里面的内容了

Answer 4

public static class ViewExtensions
    {
        /// <summary>
        /// 在控制器内获取指定视图生成后的HTML
        /// </summary>
        /// <param name="context">当前控制器的上下文</param>
        /// <param name="viewName">视图名称</param>
        /// <param name="model">视图所需要的参数</param>
        /// <returns>视图生成的HTML</returns>
        public static string GetViewHtml(this ControllerContext context, string viewName, Object param)
        {
            if (string.IsNullOrEmpty(viewName))
                viewName = context.RouteData.GetRequiredString("action");            context.Controller.ViewData.Model=param;            using (var sw = new StringWriter())
            {
                ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(context, viewName);
                var viewContext = new ViewContext(context,
                                                  viewResult.View,
                                                  context.Controller.ViewData,
                                                  context.Controller.TempData,
                                                  sw);
                try
                {
                    viewResult.View.Render(viewContext, sw);
                }
                catch (Exception ex)
                {
                    throw;
                }                return sw.GetStringBuilder().ToString();
            }
        }
    }
