-bookdata

**using system.collections.generic; using bookstore.models;  namespace bookstore.data {     public class bookdata     {         public static list<book> books = new list<book>         {             new book             {                 id=1,                 title="test1",                 author="john doe",                 publishyear=2015,                 price=10             },              new book             {                 id=2,                 title="test2",                 author="jane doe",                 publishyear=2014,                 price=15             }         };     } } 

i have read similar articles ı can't able find solution far.

since want browse "/book/new" don't need [post]

it's better create action operation , action post operation.

the action operation use when browse address, action post operation use when submitting form.

also in list view should use link new action:

@html.actionlink("create new", "new") 

as example:

[httpget] public virtual actionresult new() {     return view(); }  [httppost] public virtual actionresult new(book entity) {     try     {         if (modelstate.isvalid)         {             //save book             return redirecttoaction("list");         }     }     catch (exception ex)     {         modelstate.addmodelerror("", ex.message);     }     return view(entity);             }
