ListnumbersList = new List () { 1, 2, 3, 4, 5 }; int[] numbersArray = new ArrayBuilder (numbersList.Count).Build(i => numbersList[i]);
IEnumerableThis example initializes a new IEnumerable collection of strings, and then creates a new array of size 3 using the Build method. It then populates the array with the first 3 elements from the collection and returns the resulting array. The ArrayBuilder class is not a part of the standard C# library, but it is likely a custom implementation or a part of a third-party library.fruits = new List () { "apple", "banana", "orange", "grape" }; string[] fruitArray = new ArrayBuilder (3).Build(i => fruits.ElementAt(i));
