在更改之后或更改之前，我们将实体状态置为=修改是否重要？

using (var db = new LakshyaContext())
{
    foreach (var category in db.Categories)
    {
        db.Entry(category).State = EntityState.Modified; // before
        category.Count = 25; //Making Changes
        db.Entry(category).State = EntityState.Modified; //After
    }

    db.SaveChanges();
}
