Title
Body
The yield keyword is one of those keywords in C# that continues to mystify me, and I've never been confident that I'm using it correctly. Of the following two pieces of code, which is the preferred and why? Version 1: Using yield return public static IEnumerable<Product> GetAllProducts() { using (AdventureWorksEntities db = new AdventureWorksEntities()) { var products = from product in db.Product select product; foreach (Product product in products) { yield return product; } } } Version 2: Return the list public static IEnumerable<Product> GetAllProducts() { using (AdventureWorksEntities db = new AdventureWorksEntities()) { var products = from product in db.Product select product; return products.ToList<Product>(); } }
