Actually a hashtable isn't serializable through soap.

news:u3**************@TK2MSFTNGP11.phx.gbl... My guess is, since Soap is nothing but SoapFormatter, anything that
implements ISerializable should be soap - serializable .. so arraylist
isn't, but HashTable is.
Or you could create a SerializableArrayList by inheriting from
ArrayList, and implementing ISerializable (or something like that).

news:40**************@news.dslextreme.com... Hi,
As was pointed out whatever you return from a WebMethod needs to be
serializable to SOAP. An ArrayList is not serializable. I will be
needing to return other data types from web methods. Is there a
document, or can some one list those types that are not serializable
and the syntax for converting them?
Thanks
