My goal is to retrieve an object of the Product class as a Json for a webservice. Despite successfully loading all the values into the object, I encounter an error when trying to return it as Json. Below is my method:
<AllowAnonymous> <HttpGet> _
Public Function GetProduct() As HttpResponseMessage
Try
Dim oProduct As New Product
oProduct = Product.GetProductByID(25)
Dim jsSerializer As System.Web.Script.Serialization.JavaScriptSerializer
jsSerializer = New System.Web.Script.Serialization.JavaScriptSerializer()
Dim sbProduct As New System.Text.StringBuilder()
jsSerializer.Serialize(oProduct, sbProduct)
Dim json As String = sbProduct.ToString()
Return Request.CreateResponse(HttpStatusCode.OK, json)
Catch exc As Exception
Return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, exc)
End Try
End Function
The response:
This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Error>
<Message>An error has occurred.</Message>
<ExceptionMessage>
Exception has been thrown by the target of an invocation.

Any suggestions on how to resolve this issue?
