// Assigning a lambda expression to Func delegate FuncThe Func delegate is part of the System namespace, which is included in the .NET framework. Therefore, it does not require any separate package or library to be imported or installed.multiply = (x, y) => x * y; int result = multiply(3, 4); // result will be 12 // Using Func delegate in LINQ query List numbers = new List { 1, 2, 3, 4, 5 }; var evenNumbers = numbers.Where(num => num % 2 == 0); // evenNumbers will contain [2, 4]
