@ URL. actionlink and @ URL. Action

Problem: I want to change "Continue Learning" to an image for display in actionlink. The results show that it is always a string for processing, and MVC does not help us with this.

 
@Html. actionlink ("Continue Learning","Learning","Item","HTTP", Strhostnamekaoji,"",New{Itemid = item. Itemid, resourceid =Item. laststudyuserresid },New{})
 

Solution:

First, you can either rewrite the actionlink and perform the processing.

  Public   Static Mvchtmlstring actionlinkwithimage ( This Htmlhelper HTML, String Imgsrc, String Img_classname, String Img_width, String Img_height,

 String Actionname, String Controllername, system. Web. Routing. routevaluedictionary routevalues, String Protocolname,String  Hostname ){  VaR Urlhelper = New  Urlhelper (html. viewcontext. requestcontext );  String Imgurl = Urlhelper. Content (imgsrc); tagbuilder imgtagbuilder = New Tagbuilder ( "  IMG  "  ); Imgtagbuilder. mergeattribute (  " SRC  "  , Imgurl); imgtagbuilder. mergeattribute (  "  Class  "  , Img_classname); imgtagbuilder. mergeattribute (  "  Width  "  , Img_width); imgtagbuilder. mergeattribute (  "  Height  "  , Img_height ); String IMG = Imgtagbuilder. tostring (tagrendermode. selfclosing );  String Url = Urlhelper. Action (actionname, controllername, routevalues, protocolname, hostname); tagbuilder = New Tagbuilder ( "  A  " ) {Innerhtml = IMG}; tagbuilder. mergeattribute (  "  Href  " , URL );  Return   New  Mvchtmlstring (tagbuilder. tostring (tagrendermode. Normal ));} 

@ Html. actionlinkwithimage (item. res_item.img.tocdn (),"","63","63","Info","Item",NewRoutevaluedictionary (querystringdic ),"HTTP", Strhostnamekaoji)
 

 

Type 2: change to URL. Action.

 @ { VaR Parsed = httputility. parsequerystring ( "  Itemid =  " + Item. Itemid + "  & Resourceid =  " + Item. laststudyuserresid); dictionary < String , Object > Querystringdic = parsed. allkeys. todictionary (k => K, K => ( Object  ) Parsed [k]);} <A href = " @ URL. Action (  " Learning "  ,  " Item "  , New routevaluedictionary (querystringdic ),  " HTTP "  , Strhostnamekaoji)  " >  "  63  " Height = " 63  " Src = "  @ (Item. res_item.img.tocdn ())  " /> </A>
