Hello,

I use httpwebrequest to call wcf service.

I didn't add service reference or created a client proxy.

I have a problem. How to access DataContract class and set datamember values..?

I have a wsdl file. I can't use proxy class or add service reference .

I have seen many samples passing xml string(created manually) in request stream.

How can I access datacontract classes using this htpwebrequest..?

any suggestion is appreciated.

Not clear. The whole purpose of Data Contract is to serialize and deserialize some arbitrary object graph.
There is no such thing as "how to access a class". You receive a reference to the object representing an object graph.

I mean how can I set values to datacontract object...!
How can I discover that, the service expose datacontract class using the httpwebrequest and not service reference. by service reference, one can know the datacontract class members.

From stream on in your code? The object comes deserialized with the use of DataContractSerializer, please see. It is controlled by [DataMember] attributes and does not require anything, not even access modifiers. Please see:

If you need to access something from your semantic code, you need to make a property (properties) for that, or add internal or public access modifier to existing property (properties). Internal for access from the same assembly, public for access from other (referencing) assemblies. Please see:
