i've webservice , webmethod

[webmethod] [xmlinclude(typeof(contractcar[])) public object getobjects(cars[] cars) { return translator.toobjects(facade.getobjects(cars);  }  public static object getobjects(cars cars) { list<car>  cars =new list<country(...fillingcollection) return cars.toarray(), }  public static object toobjects(object collection) { if(collection car[]) { return convertmodelcarstocontractcars(collection), }  public contractcar[]  convertmodelcarstocontractcars(cars[] collection) { ...there rewriting pool... }

and exception @ side of client:

there error generating xml document.

i'm using function check collection send client , works.

 public static void serializecontainer(object obj)         {             try             {                 // make sure construsctor runs inside                 // try-catch block                 xmlserializer ser = new xmlserializer(typeof(object));                  textwriter w = new streamwriter(@"c:\list.xml");                 ser.serialize(w, obj);                 w.close();              }             catch (exception ex)             {                 dumpexception(ex);             }         }

interesting when collection has 1 element [webmethod] works fine, when more brokes

i changed object objects[].

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
