NUnit.Framework is a C# unit testing framework designed for Test Driven Development (TDD). It provides a wide range of assertions, a fluent interface for building test cases, and integration with Visual Studio. In addition, NUnit.Framework includes a number of utilities for working with collections, such as the List.ToArray method.
List.ToArray is a method that converts a List object to an array. The method returns an array containing the elements of the List object in the order they appear in the list. This method can be useful when you need to convert a List to an array for use in other parts of your application.
Here are some examples of using List.ToArray in C#:
1. Converting a List of strings to an array:
List list = new List { "apple", "banana", "orange" }; string[] array = list.ToArray();
2. Converting a List of integers to an array:
List list = new List { 1, 2, 3, 4 }; int[] array = list.ToArray();
