Hiii all...
I have an arraylist with user define data type...
and i need to send it trough LAN.
I am using WCF for communication and I know I have to convert arraylist to memorystream to send data...
I hve tried this method

ArrayList history = ie.getHistory();
BinaryFormatter f = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
f.Serialize(ms, history);

but I gives error because of user define data type...

I think you must specify first what is the content of you ArryList. Is this an interger or a byte[]
or any of type...

my array list has multiple columns and each column contains user define datatype... not abstract datatype...

Can you tell what is the error message it's giving ?
XeeShaN AbbAs 9-Sep-11 12:58pm    
its not error it throws exception that
"Type 'UrlHistoryLibrary.STATURL' in Assembly 'UrlHistoryLibrary, Version=1.0.4146.25771, Culture=neutral, PublicKeyToken=null' is not marked as serializable."

on that line of code f.Serialize(ms,history);

Did you apply the serialization attribute for the data transfer array content
