مثال
`var fruits = new List() { new Fruit() { Id = 1, Name = "Orange", Color = "Orange", Quantity: 3 }, new Fruit() { Id = 2, Name = "Strawberry", Color = "Red", Quantity: 12 }, new Fruit() { Id = 3, Name = "Grape", Color = "Purple", Quantity: 25 }, new Fruit() { Id = 4, Name = "Pineapple", Color = "Yellow", Quantity: 1 }, new Fruit() { Id = 5, Name = "Apple", Color = "Red", Quantity: 5 }, new Fruit() { Id = 6, Name = "Mango", Color = "Yellow", Quantity: 2 } };
// All Fruit have a quantity greater than 0. var allFruitsHaveAQuantity = fruits.All(f => f.Quantity > 0); // true // All Fruit have the Color Yellow var allYellow = fruits.All(f => f.Color == "Yellow"); // false `
