Asp. Net MVC converts PartialView and View into strings

1. Output View HTML string:

 

The code is as follows:

Copy code

/// <Summary> /// Description: outputs the View HTML string. /// </Summary> /// <Param name = "controller"> </param> /// <Param name = "viewName"> View file name </param> /// <Param name = "masterName"> motherboard page file name </param> /// <Returns> </returns> Protected static string RenderViewToString (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. Output the PartialView HTML string:

The code is as follows:

Copy code

/// <Summary> /// Description: output the PartialView HTML string /// </Summary> /// <Param name = "controller"> </param> /// <Param name = "partialViewName"> partial view file names </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 (); } }
