How to convert a list into array with Linq

n this post, I am going to explain how we can convert an generic list to simple int array with Help of Linq. Recently, I was working on an application and there I needed an Int array of for list of ids in generic list. I tried various methods and then with the help of ‘Select’ operator and ToArray method I have easily converted an generic list to the int array. Lets take a simple example. I need a contact id list from a generic list of contacts and following is my contact class. public class Contact { public int ContactId { get; set; } public string Name { get; set; } } Now I have created a new GetContacts methods to create a new Generic List of Contacts.
