Overview

The iview definition is simple to render a view based on the view context and the TextWriter object.

Realize

Implement Iviewengine

   Public classTestviewengine:iviewengine { PublicViewengineresult Findpartialview (Actioncontext context,stringpartialviewname) {            //if ViewName equals Partial-test-view, use Testpartialview            if(string. Equals (Partialviewname,"Partial-test-view", StringComparison.Ordinal)) {                returnViewengineresult.found (Partialviewname,NewTestpartialview ()); }            returnViewengineresult.notfound (Partialviewname,New[] {partialviewname}); }         PublicViewengineresult Findview (Actioncontext context,stringviewName) {            //if ViewName equals Test-view, use TestView            if(string. Equals (ViewName,"Test-view"))            {                returnViewengineresult.found (ViewName,NewTestView ()); }            returnViewengineresult.notfound (ViewName,New[] {viewName}); }    }

Implement iview

 public  class   Testpartialview:iview { public  str ing  Path {get ; set          public  async   Task Renderasync (ViewContext context) { //  There is no view, the world output browser  await  context. Writer.writelineasync (  " ); }    }

 public  class   Testview:iview { public  string Path {get ; set          public  async   Task Renderasync (ViewContext context) { await  cont Ext. Writer.writelineasync (  Span style= "color: #800000;" > " +context. Viewbag.images +  />   " ); }    }

controller

 public  class   Homecontroller:controller { public   ViewResult Index () { return          View ();             public   ViewResult TestView () {viewbag.images  =  /images/asp-net-                   Banners-01.png   ;  return  View ( " test-view   ); }         }

Start class

  Public classStartup { Public voidconfigureservices (iservicecollection services) {services. Addmvc (). CONFIGUREMVC (Options=                {                    //join the View engineOptions. Viewengines.insert (0,typeof(Testviewengine));            }); }         Public voidConfigure (Iapplicationbuilder app) {app. USEMVC (Routes={routes. MapRoute (Name:"default", Template:"{controller=home}/{action=index}/{id?}");        }); }    }
