>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.

>	    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#?
