Linked List problem

albert albert

Hi Everyone,

I have this:

[code]
private static void createRandomChar(LinkedListlist1)
        {

           //LinkedList list1 = new LinkedList();
          // LinkedList list2 = new LinkedList();

            //list = random.Next(0, 26);
            for (int i = 0; i < 10; i++)
            {
                int nextInt = random.Next(0, 26);
                var let = ('a' + nextInt);
                //list.AddLast(nextInt);
                list1.AddLast(let);
                Console.Write(list1.Last() + " ");

            }

        }
[/code]

But I get the error:
cannot convert from 'char' to 'System.Collections.Generic.LinkedListNode'

By this line: list1.AddLast(let);

THX for helping.

Sorry, forgot to cast the int back to a char:

list1.AddLast((char)let);

But then I still get the error:

Error    2    Argument 1: cannot convert from 'int' to 'System.Collections.Generic.LinkedListNode'    C:\Users\savantKing\Documents\Visual Studio 2010\Projects\WinFormShapeApp\CharacterReverseOrder\Program.cs    39    31    CharacterReverseOrder

And I have it now like this:

[code]

private static void createRandomChar(LinkedListlist1)
        {

           //LinkedList list1 = new LinkedList();
          // LinkedList list2 = new LinkedList();

            //list = random.Next(0, 26);
            for (int i = 0; i < 10; i++)
            {
                int nextInt = random.Next(0, 26);
                var let = ('a' + nextInt);
                //list.AddLast(nextInt);
                list1.AddLast(let);
               // list1.AddLast(let);
                Console.Write(list1.Last() + " ");

            }

        }

The code is only going to work if E is char, so I'd use a non-generic method instead:

private static void createRandomChar(LinkedListlist1)
{

for (int i = 0; i < 10; i++)
{
int nextInt = random.Next(0, 26);
var let = ('a' + nextInt);
list1.AddLast(let);
Console.Write(list1.Last + " "); // note that Last is a property
}

}
