Question

I’m trying to use the DataContractJsonSerializer to serialize and deserialize a c# object that contains an object[] of differing types.

I need to find all the types used by the XmlRequest and the objects in it’s object[] so I an pass the list of Types to the DataContractJsonSerializer.

The object[] in XmlRequest will contain different types. TypeX, TypeY, string, int, TypeZ

var sr = new DataContractJsonSerializer(typeof(XmlRequest), knownTypes);

Xml Request Class:

[DataContract]
    public class XmlRequest
    {
        [DataMember]
        public object[] Parameters { get; set; }

        [DataMember]
        public string Name { get; set; }

    }

I figured out how to do this through configuration instead of trying to discover these items at runtime.

<system.runtime.serialization>
        <dataContractSerializer>
            <declaredTypes>
                <add type="Whatever.XmlRequest, Whatever, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
                    <knownType type="WhateverLibary.Parameter, WhateverLibary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
                </add>
            </declaredTypes>
        </dataContractSerializer>
    </system.runtime.serialization>
