Unable to access Web Method after deploying into the server

Question

Hi,
I'm Unable to access Web method after deploying into the server.
My Web method is 
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json )]
public object getOwners()
DataTable dt = _qbObj.returnDDLData("employeedetails", "EmpID", "EmpFirstName");
if (dt == null)
return new { Result = "Error", Options = "Error getting data" };
string[] strAttributes = { "ID", "Name" };
string[] strColName = { "EmpID", "EmpFirstName" };
List<SolOwners> lstObject = convertToList(dt, strAttributes, strColName, new SolOwners());
var owners = lstObject.Select(c => new { DisplayText = c.Name, Value = c.ID });
return new { Result = "OK", Options = owners };
When I.m accessing that method after deploying into server, I got following error.
System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: &lt;&gt;f__AnonymousType9`2[System.String,System.Collections.Generic.IEnumerable`1[&lt;&gt;f__AnonymousTypea`2[System.String,System.String]]] cannot be serialized because it does not have a parameterless constructor.
