A better example of parsing and saving an object from JSON using the Single Responsibility Principle

BetterSaveExample.cs

public void SaveFromJson(string jsonData, DbContext saveContext)
{
  Person person = GetFromJson(jsonData);
  Save(person, saveContext);
}

public Person GetFromJson(string jsonData)
{
  try
  {
    JavaScriptSerializer serializer = new JavaScriptSerializer();
    Person person = serializer.Deserialize<Person>(jsonData);
    return person;
  }
  catch (ArgumentException argEx)
  {
    //TODO: Handle this exception.
  }
  catch (ArgumentNullException argNullEx)
  {
    //TODO: Handle this exception.
  }
  catch (InvalidOperationException badOpEx)
  {
    //TODO: Handle this exception.
  }
}

public void Save(Person person, DbContext saveContext)
{
    //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();
}
