C#

string[] dinosaurs = {"Compsognathus", "Amargasaurus", "Oviraptor",
            "Velociraptor",  "Deinonychus",  "Dilophosaurus",
            "Gallimimus",    "Triceratops" };
        //Predicate<string> dinoType=null;
        //string lastvalue = Array.FindLast(dinosaurs, dinoType).ToString();
        string lastItem = dinosaurs[dinosaurs.Length - 1];

Plus, this has nothing to do at all with any generic method :)

Solution 6

try this

int i=name.length-1;

string last=name[i].ToString();

Solution 4

Maybe that would do:

C#

public int LastNonEmptyIndex(string[] array)
{
   int i = array.Length - 1;
   do {
      if (!string.IsNullOrEmpty(array[i])) {
         break;
      }
   } while (--i > -1);
   return i;
}

This function returns the last index of an array containing a non emty/null value.

Hope this helps.

Nice piece of code ;)

Thank you :)
Edit : maybe I missed the static keyword in the method declaration that would make it even more useful ^^
