c# - How can i display image in image link? -

i want create image link can't see image it's extension methods:

 public static mvchtmlstring actionimage(this htmlhelper htmlhelper,  string controller,  string action,  object routevalues,  string imagepath,  string alternatetext = "",  object htmlattributes = null)     {         var anchorbuilder = new tagbuilder("a");          var url = new urlhelper(htmlhelper.viewcontext.requestcontext);         anchorbuilder.mergeattribute("href", url.action(action, controller, routevalues));         var imgbuilder = new tagbuilder("img");         imgbuilder.mergeattribute("src", url.content(imagepath));         imgbuilder.mergeattribute("alt", alternatetext);         var attributes = (idictionary<string, object>)htmlhelper.anonymousobjecttohtmlattributes(htmlattributes);         imgbuilder.mergeattributes(attributes);         string imghtml = imgbuilder.tostring(tagrendermode.selfclosing);         anchorbuilder.innerhtml = imghtml;         return mvchtmlstring.create(anchorbuilder.tostring());     } 

and using in view:

@foreach (var item in model) {    .    .     <div>         image:         @html.actionimage("controllername", "action",          "routevalues", item.imageaddress.tostring())     </div>    .    . } 

imageaddress string doesn't work,there no difference when use specific address like

@html.actionimage("controllername", "action",          "routevalues", "c:\1.jpg") 

only when use address work good:

"../../content/images/1.jpg" 

what's problem? help, sorry english
