asp.net : Can I make a class from XML? Serialize?
Do you mean during Run-time? If so then I don't believe so. Or do you mean at Design-time? If so then it is "possible" but you would need to either find an application that can create a class from an XML file or make one yourself, out of interest what purpose would it serve? Nick.

I am not sure if you want to do it at runtime, but if you do, create a C#
class from the XML (hey you can even do it with XSLT ;-) and use the free csc.exe (C# compiler) in your windows/Microsoft.NET folder to compile. If you really want to make things hard for yourself, I know (heard) there are helper classes to create Assemblies straight without code. I don't have the book with me, but they seem to exists. naaaaaa, option 1 would be far cheaper.

Hi guys,
I need a way to dynamically change (or create) a custom class using an external xml file. Can this be done at all? This is what the class looks like: Public Class MemberData Private _EmailGUID As String Private _Email As String Private _FirstName As String Private _LastName As String Private _Title As String Private _Company As String Private _Address As String Private _PostalCode As Integer Private _City As String Private _Phone As String Private _Active As Integer Private _RegDate As DateTime Private _ChangeDate As DateTime Public Sub New() MyBase.New() _EmailGUID = "" _Email = "" _FirstName = "" _LastName = "" _Title = "" _Company = "" _Address = "" _PostalCode = 0 _City = "" _Phone = "" _Active = 0 _RegDate = Nothing _ChangeDate = Nothing _SoftBounces = 0 _HardBounces = 0 _GroupIDs = "" End Sub Public Property EmailGUID() As String Get Return _EmailGUID End Get Set(ByVal Value As String) If ((Value Is Nothing) OrElse (Value.Length = 0)) Then Throw New Exception("The email address identifier cannot be empty") End If _EmailGUID = Value End Set End Property Public Property Email() As String Get Return _Email End Get Set(ByVal Value As String) If ((Value Is Nothing) OrElse (Value.Length = 0)) Then Throw New Exception("The email address cannot be empty") End If _Email = Value End Set End Property [...] End Class Thanks. Regards Jonah
Hi Jonah,
Sorry I have no idea about Web Services at the moment, I haven't gotten into any of that. But by the sounds of things I am sure that you can make the engine that you want, I just do not have the knowledge in that field to provide enough assistance, sorry :-( Maybe someone else will offer advice here.

Hi Nick,
Here's the deal; I'm trying to create a Web Service to be run as an engine for several client web applications. The engine takes care of all communication with each database. The reason I say 'each' is that a customer may use their own SQL server. All this is just testing, but I came up with the idea when looking at an example how to dynamically create stored procedures using XML files (http://www.fawcette.com/xmlmag/2002_11/online/xml_wahlin_11_05_02/). Since I use the MemberData class in the function that contains the call to the Stored Procedure, and I can change the parameters in the SP using an XML file, why shouldn't I be able to also make the MemberData class dynamic. Say, one customer needs to add "Department" to the MemberData class. This can easily be done in the XML file for the SP, but how to add it to the MemberData class? I just don't want to re-build the entire Web Service application. I'm not sure though if I explained this so people can understand me... =) Jonah "Nak" <a@a.com> skrev i meddelandet news:uc0t59eXDHA.2464@TK2MSFTNGP09.phx.gbl...

Thanks anyway Nick! :-)

Jonah,
It seems clear, but it is not for me, you say a Web Service to run as an engine (Webservice?) for several client web applications. There is a lot of difference in that. When it is a webService who runs on side A and then takes action on Side B will be very complex with authoring, but maybe I see things wrong. Like Nick I do not know if I can help you, I do know very few from SQL but maybe this group can help you together. And of course, when this solution can made with C# it can be made better with VB.Net. Cor "Jonah Olsson" <jonah@IHateSpam.com> schreef in bericht news:uWPr9MfXDHA.2640@TK2MSFTNGP09.phx.gbl...
