asp.net - Not able to understand error message: The best overloaded method match for 'System.Web.Mvc.MvcHtmlString.Create(string)' has some invalid arguments -

i having error message:

the best overloaded method match 'system.web.mvc.mvchtmlstring.create(string)' has invalid arguments

what wrong in code? seems not reach controller.

i having following piece of code in view:

 var list = @mvchtmlstring.create(myproject.controllers.testcontroller.getlist(datetime.today)); 

in controller have following piece of code:

 public static jsonresult getlist( datetime date, int id=0)     {         return new jsonresult         {             data = mymodelmodel.userslist(id, date),             jsonrequestbehavior = jsonrequestbehavior.allowget         };     } 

userslist return follows:

> list<datetime> dateslist = new list<datetime>();  return dateslist.stringify(); 

getlist() returns jsonresult mvchtmlstring.create obviousely accepts string
