where to declare webmethod for abstract class .. ??

Question

I have a class 'Prod' which is abstract because It has a function printsome() which is my abstract method ( this in turn is what my webservice is ) I have 3 classes P1 P2 P3 which extend 'Prod'. and each define their own printsome() like P1's printsome displays this is first P2's .... second one  P3's function displays know its third My problem is WHERE TO WRITE THE Webmethod... i mean do i startwith and say each of P123 are my webservices .. ?? 1) If this is the case if i declare P1 as webservice then we have like public class P1:System.Web.Services.WebService ( And also we need to extend class 'prod' ... ie. P1:prod ) ... and this becomes multiple inheritance... and cannot be done .. 2) If P123 are not my webservices then i have to declare 'prod' as my Webservice so i have to put in my 'prod' class [WebMethod] abstract public void printsome() .. and as we know already 'prod' is an abstract class and then write the P1 P2 P3 extending 'prod' and overriding the function in their own way Now when we invoke at some other application this webservice we need to add the webreference to the webservice and so now we HAVE to create an instance of 'prod' - BUT THIS CANNOT be done since it is an abstract class Please get me out of this problem ... how do i access the printsome() of each P1P2P3 Thanks in advance Skar

[WebService(Namespace=http://your_url.com)]class prod:System.Web.Services.WebService { [WebMethod] abstract void printsome(); // rest of the other nonweb methods here and code } [WebService(Namespace=http://your_url.com)] class P1:prod { [WebMethod] // <- This is the Actual Callable Method public void printsome() { // code here } } You instanciate and call..... prod p = new P1() p.printsome();

could you be a little more elaborate please... ? is this what you meant .. class prod:System.Web.Services.WebService { [WebMethod] abstract void printsome(); // rest of the other nonweb methods here and code } class P1:prod { public void printsome() { // code here } } But if this is the case .... how do i instantiate P1 .. ?? Please clarify with an example if you can... that would be really helpful Thanks

You DERIVE Prod from WebService.... but ATTRIBUTE P1P2P3 [WebService(Namespace=http://dynamicconcepts.us/webservices/testing)]
