I decided to create a function to encapsulate many lines of codes into 1 line of code. So hence this example script. What I could not get to work is get the class's Type and pass it on to ObjectContent's parameter for it to work.

Take a look at xmlObjectType variable in ObjectContent<xmlObjectType>(....) and the System.Type assignment to xmlObjectType using GetType() on the passed-in paramater object. What do you guys do to get the actual object type for this to work with ObjectContent?

public class XmlError
{
    public string Message { get; set; }
}
public class XmlBuilderTools 
{
   public HttpResponseMessage ErrorResponse(object parmXmlErrorLayout)
   {
       HttpResponseMessage httpResponseMsg = new HttpResponseMessage();
       Type xmlObjectType = parmXmlErrorLayout.GetType();

       httpResponseMsg.StatusCode = HttpStatusCode.BadRequest;
       httpResponseMsg.Content = new ObjectContent<xmlObjectType>(parmXmlErrorLayout, new XmlMediaTypeFormatter());
   }
}

//Acutual scripts...
XmlBuilderTools xmlBuilderTools = new XmlBuilderTools();
XmlError xmlError = new XmlError();

xmlError.Message = "Foo";

return xmlBuilderTools.ErrorResponse(xmlError);

Edited - Found a workaround to this problem. You do not have to invoke it, instead do use other object overloading that works. Me Duh!

 httpResponseMsg.Content = new ObjectContent(parmXmlErrorLayout.GetType(), parmXmlErrorLayout, new CustomXmlFormatter());

You simply can't do that. You have to use reflection instead.

MethodInfo method = yourInstance.GetType().GetMethod("ObjectContent").MakeGenericMethod(new Type[] { xmlObjectType });
method.Invoke(this, new object[] { parmXmlErrorLayout, new XmlMediaTypeFormatter() });

Otherwise pass the type as a parameter to method too.
