assign object from the list using its index

Question

If I have list of Author objects like

List<Author> authors = new List<Author>{ 
       new  Author { Id = 1, Name = "John Freeman"};
       new  Author { Id = 1, Name = "Adam Kurtz"};
};

this example is actually wrapped in static method which returns list of authors.

Inside my other object there is property Authors of type List<Author>. Now I want to assign second author from the list to Authors property.

I thought that I can use Authors = GetAuthors()[1].ToList(); but I cannot access ToList() on index specified author.

to clarify

private static List<Author> GetAuthors() return list of authors (example above). 
var someObject = new SomeObject()
{
   Authors = // select only Adam Kurtz author using index 
             // and assign to Authors property of type List<Author>
};

not sure I understand your question do you need Authors = new List<Author>(){someObject[1]}; ? — jbl

If I understand you correctly, you want a List<Author> with a single author in it. Using ToList() on a single Author object is then not valid syntax.

Try this: Authors = new List<Author>() { GetAuthors()[1] };

You can't assign a single author to list<Author>, so you will have to create a list (of single author) to assign it..

Authors = new List<Author>() {GetAuthor()[1]};

I don't know, why you want to take based on index, ideally you should write a query based on ID of author to get value, so that it won't create any issue in future..

Like: Authors = new List<Author>() {GetAuthor().FirstOrDefault(x=>x.ID==2)};

A sollution with LINQ would be GetAuthors().Skip(1).Take(1)

Edit: Ignore all that. You're working with lists. What you actually need is to use GetRange:

GetAuthors().GetRange(1,1);
