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();
            }
        }
