Roy (see above) said  maybe you could just add the first and last name together separated by a space  except you probably want to use a Dictionary or something such as that. I do not understand the question though; would the above work? If not and you still need help then please explain.

Here we are Dave Lists can be of any type class struct arrays of ints doubles etc can also be array of arrays Lists of Lists Lists of objects which can then be cast to types... public class namepairs { public string a b; public namepairs(string first string second) { a = first; b = second; } } List myList = new List (); myList.Add(new namepairs(bob steve)); myList.Add(new namepairs(bob ben)); myList.Add(new namepairs(ben steve));

I never used them myself but I think a dictionary could do what you want here (but then two strings instead of a string and int). http://www.c-sharpcorner.com/UploadFile/mahesh/2002/ Or maybe you could just add the first and last name together separated by a space and store that in a list?

Hi Please find the example hope it helps you. Just understand the logic of List because it list can save only 1 value at a time. using System; using System.Collections.Generic; class Program { static void Main() { List cities = new List (); // List of city names cities.Add(San Diego); // String element 1 cities.Add(Humboldt); // 2 cities.Add(Los Angeles); // 3 cities.Add(Auburn); // 4 // Write each city string. foreach (string city in cities) { Console.WriteLine(city); } } } --- Output of the program --- San Diego Humboldt Los Angeles Auburn

In .Net 4.0 you could use Tuples. Take a look here: http://blog.dynamicprogrammer.com/2009/05/25/TupleANewTypeOnNet40.aspx Otherwise you can use List >. List > myList = new List >(); List listTwoStrings = new List (2); listTwoStrings.Add(Bob); listTwoStrings.Add(Steve); myList.Add(listTwoStrings);
