I have my WCF service returning data both in XML and JSON format.
One functios has to return a List, because I don't know which class will be used to fill this list.
So, I have my class:
public class WrapHome
{
public WrapHome() { }
private string p_TITOLO { get; set; }
public string TITOLO { get { return p_TITOLO.ToString(); } set { p_TITOLO = value; } }
private List<object> p_CHART { get; set; }
public List<object> CHART { get { return p_CHART; } set { p_CHART = value; } }
}
and my WCF declaration:
[OperationContract]
[WebGet(UriTemplate = "datiHome.xml?token={token}&p1={p1}&p2={p2}", ResponseFormat = WebMessageFormat.Xml)]
List<WrapHome> GetDatiHomeXML(string token, string p1, string p2);
The output is correctly set, but, when it has to return it converted in XML (or JSON), it re-calls the method and finally give the err_connection_reset error.
I know the problem is the List, because if I comment it, it works. How can I use my List in my WCF output?
If you need more details, ask me without any problem.
You could define
[KnownType(typeof(MyChildObject0))]
...
[KnownType(typeof(MyChildObjectM))]
public class MyBaseObject { ... }
public class MyChildObject0 : MyBaseObject { ... }
...
public class MyChildObjectM : MyBaseObject { ... }
Or you could add the attribute only once and define static method that returns all M+1 types at once.
and modify:
public class WrapHome
{
...
public List<MyBaseObject> CHART { get;set; }
}
