Asp.Net MVC 把PartialView、View转换成HTML字符串

在开发中有时要在后台获得某个View 或者 PartialView 生成的字符串，只要你熟悉Asp.Net MVC  生命周期就能理解和敲出下面的代码。没什么高深的，直接上代码：

 

1、输出View HTML 字符串：

 

        /// <summary>

        /// 描述：输出View HTML 字符串

        /// </summary>

        /// <param name="controller"></param>

        /// <param name="viewName">视图文件名</param>

        /// <param name="masterName">母板页文件名</param>

        /// <returns></returns>

        protected static string RenderViewToString(Controller controller, string viewName, string masterName)

        {

            IView view = ViewEngines.Engines.FindView(controller.ControllerContext, viewName, masterName).View;

            using (StringWriter writer = new StringWriter())

            {

                ViewContext viewContext = new ViewContext(controller.ControllerContext, view, controller.ViewData, controller.TempData, writer);

                viewContext.View.Render(viewContext, writer);

                return writer.ToString();

            }

        }

 

 

2、输出PartialView HTML 字符串：
 

 

        /// <summary>

        /// 描述：输出PartialView HTML 字符串

        /// </summary>

        /// <param name="controller"></param>

        /// <param name="partialViewName">部分视图文件名</param>

        /// <returns></returns>

        protected static string RenderPartialViewToString(Controller controller, string partialViewName)

        {

            IView view = ViewEngines.Engines.FindPartialView(controller.ControllerContext, partialViewName).View;

            using (StringWriter writer = new StringWriter())

            {

                ViewContext viewContext = new ViewContext(controller.ControllerContext, view, controller.ViewData, controller.TempData, writer);

                viewContext.View.Render(viewContext, writer);

                return writer.ToString();

            }

        }
