they give class called signedrequesthelper, make call this:

   public static void main()         {             signedrequesthelper helper = new signedrequesthelper(my_aws_access_key_id, my_aws_secret_key, destination);              /*              * helper supports 2 forms of requests - dictionary form , query string form.              */             string requesturl;             string title;              /*              * here itemlookup example request stored dictionary.              */             idictionary<string, string> r1 = new dictionary<string, string>();             r1["service"] = "awsecommerceservice";             r1["version"] = "2009-03-31";             r1["operation"] = "itemlookup";             r1["itemid"] = item_id;             r1["responsegroup"] = "small";              /* random params testing */             r1["anurl"] = "http://www.amazon.com/books";             r1["anemailaddress"] = "foobar@nowhere.com";             r1["aunicodestring"] = "αβγδεٵٶٷٸٹٺチャーハン叉焼";             r1["latin1chars"] = "ĀāĂ㥹ĆćĈĉĊċČčĎďĐđĒēĔĕĖėĘęĚěĜĝĞğĠġĢģĤĥĦħĨĩĪīĬĭĮįİıIJij";              requesturl = helper.sign(r1);             title = fetchtitle(requesturl);              system.console.writeline("method 1: itemlookup dictionary form.");             system.console.writeline("title \"" + title + "\"");             system.console.writeline(); } 

you need use itemlookup (like example) set idtype isbn. set itemid actual isbn. here details on itemlookup:
