I have a requirement to serialize json a data by clubbing multiple data. thought of creating a dynamic object. Got a scenario that json name should be a hyphen separated name(for ex : attribute-name) and also need add a property with the name as default.
dynamic jsonDynamic = new System.Dynamic.ExpandoObject();
//**jsonDynamic.default** How to achieve this
//**jsonDynamic.attribute-name** How to achieve this
