示例1: AgregarActividad
public static object AgregarActividad(string actividadJSON, string preguntasJSON, string respuestasJSON)
{
Actividade actividad = JsonConvert.DeserializeObject<Actividade>(actividadJSON);
List<Pregunta> preguntas = JsonConvert.DeserializeObject<List<Pregunta>>(preguntasJSON);
List<Respuesta> respuestas = JsonConvert.DeserializeObject<List<Respuesta>>(respuestasJSON);
foreach (Pregunta p in preguntas)
{
foreach (Respuesta r in respuestas)
{
if (p.ID == r.FK_Pregunta)
{
p.Respuestas.Add(r);
}
}
}
//Converting List to EntitySet
var preguntasEntitySet = new EntitySet<Pregunta>();
preguntasEntitySet.AddRange(preguntas);
actividad.Preguntas = preguntasEntitySet;
using (var dataContext = new OBJ_REDDataContext())
