Default Constructors and Proxy Classes

Hi,

I have a question regarding default constructors and the way svcutil generates proxy. I‘m not sure if I’m thinking in the right way in exposing these classes as DTO’s. I greatly value your inputs,

With the same example given below

[DataContract]

public class MyClass

{

private List<Child> _children;

void MyClass

{

_children = new List<Child>();

}

[DataMember]

Public List<Child> Children

{

Get{return _children;}

set{_children = value;}

}

}

I’m trying to expose this class via a service agent. And for that I’m using svcutil to generate the DTO Classes. How can I ensure that the client when it tries to do the following does not get a null value

MyClass myInstance = new MyClass();

myInstance.Children.Add(new Child()); //Throws an exception as the Children is null

Am I doing the right thing in exposing these proxy class as DTO I greatly appreciate your response.

Thanks much,

Kumar
