custom datatypes

[Gibb]

Hi All.. i need help in this issue...
Public Attributes & Properties for shared classes amoung webservice are
accessible, but how can we call the methods.
i have a webMethod that returns a custom datatype to the client, where i
need to call a method of that returned class. here is an example :

//Web Service Namespace
public class Meeting
{
public string subject;
private ArrayList attachments;

public void AddAttachment( string fileName, byte[] data )
{
// Code to do manipulate the attachmentsand add it to my ArrayList
}
}

// My Web Method
[WebMethod()]
public Meeting getMeeting( int meetID )
{
// code goes here to get the required meeting
Meeting meeting = new Meeting();
return meeting;
}

[WebMethod()]
public void UpdateMeeting( Meeting meeting )
{
// Do any Operation Here
}

-----------------------------------------------------------------
// Now Here it Goes My Client Code

public void UpdateMeeting( int meetID )
{
//Call my Web Service
MeetingWS proxy = new MeetingWS();
//Here i Need to Define the Meeting Object
MeetingWS.Meeti ng m = new MeetingWS.Meeti ng();
m = proxy.getMeetin g( meetID );
// here goes the problem
m.AddAttachment ( "anything", myArrOfBytes ); // Can't Call this Methods
where
m.fileName = "MyFileName " // This is accessible
// if this problem is solved then i want to update that meeting by calling
the web method
proxy.UpdateMee ting( m );

}
-----------------------------------------------------------

Many Thanks.
