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 } };
// Check if any Fruits have a quantity greater than 20 var anyFruitGreaterThanTwenty = fruits.Any(f => f.Quantity > 20); // true
// Any Fruit with color Green var anyGreen = fruits.Any(f => f.Color == "Green"); // false
var hasFruits = fruits.Any(); // true
var hasYellowFruit = fruits.Any(f => f.Color == "Yellow"); // true `
