Visual Basic  C   and C   all have syntax for accessing the Item property without using its name  Instead  the variable containing the List is used as if it were an array   List index    See for instance  https   msdn microsoft com en-us library 0ebtbkkc v vs 110  aspx

You can use the ElementAt extension method on the list   For example      Get the first item from the list  using System Linq   var myList   new List lt string gt    Yes    No    Maybe    var firstItem   myList ElementAt 0       Do something with firstItem

NET List data structure is an Array in a  mutable shell    So you can use indexes for accessing to it s elements like   var firstElement   myList 0   var secondElement   myList 1     Starting with C  8 0 you can use Index and Range classes for accessing elements  They provides accessing from the end of sequence or just access a specific part of sequence   var lastElement   myList  1      Using Index var fiveElements   myList 2  7      Using Range  note that 7 is exclusive   You can combine indexes and ranges together   var elementsFromThirdToEnd   myList 2   0      Index and Range together   Also you can use LINQ ElementAt method but for 99  of cases this is really not necessary and just slow performance solution

Old question  but I see that this thread was fairly recently active  so I ll go ahead and throw in my two cents      Pretty much exactly what Mitch said  Assuming proper indexing  you can just go ahead and use square bracket notation as if you were accessing an array  In addition to using the numeric index  though  if your members have specific names  you can often do kind of a simultaneous search access by typing something like    var temp   list1  DesiredMember      The more you know  right
