how can I get n random names from the list given by user?

i did write , but it gets just the nam:

var namenListe = new List<string>();
while(true)
{
    Console.WriteLine("Geben Sie die Namen ein ; "); 
    string name = Console.ReadLine();
    Console.WriteLine("Die namen : ");
    namenListe.Add(name);

    for (int i = 0; i < namenListe.Count; i++)
    {
        Console.WriteLine(namenListe);
    }
