The problem is that you are returnin an object[] and you need to convert or cast it.

Your GetList() function in your web-service hasn't been defined properly. Make sure that the return type is an ArrayList public System.ArrayList GetList() { }

this is my webservice: [WebMethod] public ArrayList GetDevicesList() { Hashtable DeviceList = new Hashtable(10); for (int i = 0; i < 10; i++) { DeviceList.Add("test"+i.ToString(),"test"); } ArrayList a = new ArrayList(); a.Add(DeviceList); return a; } of course my hash table will later be set with real values, but for now i am just testing my architecture. so it does return ArrayList. how can i use it from my client?
