HI

After much reading of rick Strahl's articles, I settled on a method to pass objects fron VFP to a C# Web Service, by exposing all my classes to COM and creating similar classes on the NET side as described in the article. I have the Web service running and passing objects back and forth happily. It was a long exhausting journey of 2 steps forward one step back.

I now have a couple of questions about C#

1. In VFP If I have a class:

Define Class RequestObject As Session
    SessionID = ""
    MemberID = ""
    LoginName = ""
Enddefine
Define Class MemberCC As Session
    CCName = ""
    CCNumber = ""
    CCExpiry = ""
    CCType = ""
EndDefine

At runtime I can do this:

AddProperty(RequestObject,"oCreditCard")
This.oCreditCard = Createobject("MemberCC")

to get a Complex Class:

RequestObject
    SessionID = ""
    MemberID = ""
    LoginName 
    oCreditCard
        CCName
        CCNumber
        CCExpiry
        CCType

This is very easy to do at the VFP end.

If I have a similar class in C# and want to add a single property say - "newEmail" at runtime
What is the command to add it to the class below?

[Serializable]
public class RequestObject
    {
        public string SessionID = "";
        public string MemberID = "";
        public string LoginName = "";
    }

2. If I have the above class and another class as below :

[Serializable]
    public class csBankDetails
    {
        public string csAcctname = "";
	    public string csBankacct = "";
	    public string csBankName = "";
	    public string csBanksid  = "";
	    public string csBranchName = "";
    }

and at runtime I instantiate the RequestObject class and want to add the csBankDetails class to it to create a complex object like below, how can I do that in C# at runtime to get a complex class as below?

SessionID
MemberID
LoginName
csBankDetails
    csAcctname
    csBankacct
    csBankName
    csBanksid
    csBranchName

The complete logic for my application is in VFP and it would take too long and too much maintenance to convert the logic to C#.

I need to return from the Web Service the RequestObject, except that for some calls I need to add on the CreditCard details and/or Address Details and/or Bank Details. The combinations vary:

Return ResponseObject
Return ResponseObject wiich will include Customer details like name, DOB, emai, phone etc
Return ResponseObject + CC Details+ Bank Details
etc. and combinations of the above and more.

Is this even possible in C#?
