NVelocity Template Engine is a good thing, but it has not been a new version for a long time. The following code is free to use. If you have time to complete a fully functional version, please send me a copy. Thank you.

Using NVelocity;
Using NVelocity. App;
Using NVelocity. Context;

Public class NVelocityViewEngine: VirtualPathProviderViewEngine
{
Public NVelocityViewEngine ()
{
ViewLocationFormats = new []
{
"~ /Views/{1}/02.16.htm ",
"~ /Views/{1}/02.16.html ",
"~ /Views/Shared/share0).htm ",
"~ /Views/Shared/custom 02.16.html ",
};
}

Protected override IView CreatePartialView (ControllerContext controllerContext, string partialPath)
{
Throw new NotImplementedException ();
}

Protected override IView CreateView (ControllerContext controllerContext, string viewPath, string masterPath)
{
Return new NVelocityView (controllerContext, viewPath );
}
}

Public class NVelocityView: IView
{
Private static VelocityEngine engine;
Private string viewPath;
Private ControllerContext controllerContext;

Static NVelocityView ()
{
Engine = new VelocityEngine ();
Engine. SetProperty ("resource. loader", "file ");
Engine. SetProperty ("file. resource. loader. path", HttpContext. Current. Server. MapPath ("~ "));
// Engine. SetProperty ("file. resource. loader. cache", true );
// Engine. SetProperty ("file. resource. loader. modificationCheckInterval", 10L); // seconds
Engine. SetProperty ("input. encoding", "UTF-8 ");
Engine. Init ();
}

Public NVelocityView (ControllerContext controllerContext, string viewPath)
{
This. controllerContext = controllerContext;
This. viewPath = viewPath. StartsWith ("~ ")? ViewPath. Substring (1): viewPath;
}

Public void Render (ViewContext viewContext, System. IO. TextWriter writer)
{
Var context = new VelocityContext ();
Var template = engine. GetTemplate (viewPath );

Context. Put ("ViewData", viewContext. ViewData );
Context. Put ("TempData", viewContext. TempData );

Template. Merge (context, writer );
}
}

Try it.

Public class TestController: Controller
{
Public ActionResult Index ()
{
ViewData ["user"] = new
{
Name = "Tom ",
Age = 13
};

Var view = new NVelocityView (this. ControllerContext, "/Views/Test/Index.htm ");
Return View (view );
}
}

/Views/Test/Index.htm
<Html xmlns = "http://www.w3.org/1999/xhtml">
<Head>
<Title> </title>
</Head>
<Body>
$ ViewData. User. Name <br/>
</Body>
</Html>

Of course, we can also register it as the default View engine, so that you do not need to create an IView every time and pass it to View ().

Public class MvcApplication: System. Web. HttpApplication
{
Protected void Application_Start ()
{
ViewEngines. Engines. Clear ();
ViewEngines. Engines. Add (new NVelocityViewEngine ());

RegisterRoutes (RouteTable. Routes );
}
}

Or write an IResultFilter, which is marked on the ActionMethod that requires NVelocityViewEngine.

Public class nvelocityviewattriter: ActionFilterAttribute
{
Public NVelocityViewAttribute ()
{
}

Public nvelocityviewattripath (string viewPath)
{
This. ViewPath = viewPath;
}

Public string ViewPath {get; set ;}

Public override void OnResultExecuting (ResultExecutingContext filterContext)
{
If (String. IsNullOrEmpty (ViewPath ))
{
Foreach (var ext in new [] {"html", "htm "})
{
ViewPath = String. Format ("~ /Views/{0}/{1}. {2 }",
FilterContext. RouteData. GetRequiredString ("controller "),
FilterContext. RouteData. GetRequiredString ("action "),
Ext );

If (System. IO. File. Exists (HttpContext. Current. Server. MapPath (ViewPath) break;
}
}

Var result = filterContext. Result as ViewResult;

If (result! = Null)
{
Result. View = new NVelocityView (filterContext, ViewPath );
}
}
}

Now it is more convenient to use.

[NVelocityView]
Public ActionResult Index ()
{
ViewData ["user"] = new
{
Name = "Tom ",
Age = 13
};

Return View ();
}

You can also manually specify a template.

[NVelocityView ("/Views/Test/Index2.htm")]
Public ActionResult Index ()
{
ViewData ["user"] = new
{
Name = "Tom ",
Age = 13
};

Return View ();
}
