c# mvc 在控制器中动态解析cshtml文件并获取对应的html代码

在控制器中使用：

 ViewBag.aaaa= "******";
 string pageContent = Utils.GetViewHtml(this.ControllerContext, "/Views/Shared/PayParameterView.cshtml", null);
                

具体方法

            /// 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( 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();
                }
            }

在对应的页面上可以取到控制器中的ViewBag数据
