An example of parsing an object's data from its representation and saving it somewhere all in one method (not the best approach).

SavePersonJsonExample.cs

public void SaveFromJson(string jsonData, DbContext saveContext)
{
  try
  {
    JavaScriptSerializer serializer = new JavaScriptSerializer();
    Person person = serializer.Deserialize<Person>(jsonData);
    //This is just an example, but in prod code you'd need 
    //to make sure the entity doesn't already exist.
    saveContext.Entry<Person>(person).State = System.Data.EntityState.Added;
    saveContext.SaveChanges();
  }
  catch (ArgumentException argEx)
  {
    //TODO: Handle this exception.
  }
  catch (ArgumentNullException argNullEx)
  {
    //TODO: Handle this exception.
  }
  catch (InvalidOperationException badOpEx)
  {
    //TODO: Handle this exception.
  }
}
