Passing custom object to web service
-
I have a custom object which is is a simple model with only a few strings and booleans as fields. I would like to pass this to a web service. Is there anyway to do this? I currently have the class in both projects but it says "CustomClass is not of type web_service_name.CustomClass" when I try to pass it in the consuming project. How can i tell it they are the same class?

You can only use 1 definition of the class. Both the UI and the WebService needs to reference a dll that has the definition of the class. It needs to also be serializable because it will be converted to xml for the transaction _ Public Class Hello public sName as string . . . End class

Thanks but that has nothing to do with my problem. They are both the same definition. What I am trying to do is to get it to recognise that.

You said, that you have the class in both projects. Does both mean you have the class defined in each or referenced in each? Defined will not work, it must be referenced in each....
for further clarification... it compares the object using the full assembly name if your ui project is codeproject and your class is hello codeproject.hello - is the full class name if your webservice is webproject and your class is hello webproject.hello - is the full class name does codeproject.hello = webproject.hello ? you think it does but the full assembly names do no match so it thinks they are different objects...

Exactly!!! How can I get these to be the same? Surely it shouldn't be too difficult to just send an object with only a couple of string in it!
that's what I'm talking about with referencing a dll... create a dll (let's call it A) put the definition of the class Hello in A in your exe reference A use A.Hello everywhere in your code in you webservice reference A use A.Hello everywhere in your code because the full assembly name is A.hello...when you pass A.hello to your webservice it will see that A.Hello = A.Hello and accept the object as being the same... -

Thanks for you help so far. I have compiled the class into a dll and placed it into the bin directory. Now what do I do with it?
i'll assume your exe and your webservice are in the same solution add the dll project to the solution in your exe project, do an add reference and point to the dll project - don't move the dll to the bin when you compile the dll will come along automatically when you compile in your webservice project, do an add reference and point to the dll project - don't move the dll to the bin when you compile the dll will come along automatically when you compile

Okay I have imported it into both projects so they are both using the dll. But it still says "namespace.classname can not be converted to web_service_name.classname" Same problem as before.
Did you remove the old class definitions from your code?

are you using web reference or going after the webservice dynamically? if web reference -- try to remove the reference and re-add it...
-
I am adding a web reference to it. I have removed it, recompiled the service and added it again and still has the same problem.
Well I have managed to achieve what I want to but in a pretty crude way. I have written a function to serialize a class and one to deserialize it. Like this -
Public Function Object2XML(ByVal obj As Object) As String Dim SW As New StringWriter Dim Ser As New XmlSerializer(obj.GetType()) Try Ser.Serialize(SW, obj) Return SW.ToString Catch ex As Exception Throw ex End Try End Function Public Function XML2OBject(ByVal xml As String, ByVal Type As Type) As Object Dim Obj As New Object Dim SR As New StringReader(xml) Dim Serializer As New System.Xml.Serialization.XmlSerializer(Type) Try Return Serializer.Deserialize(SR) Catch ex As Exception Throw ex End Try End FunctionBut surely there is a better way to do it than this? -

if you want, you can email your solution and I can take a quick look (strip out any unnecessary code)

Thats a very kind offer but It is as very large project and I can't strip it easily. Don't think my boss would appreciate me sending you the whole of our site. Thanks anyway. Have you managed to pass a custom class to a web service before successfully?
