Linkedlistnode

[maniacCow]

Hi,

I found a source code from http://dotnetperls.com/linkedlist.
I wanna do something like them regarding the linkedlistnode.
Below is the code:-

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        //
        // Create a new linked list.
        //
        LinkedList<string> linked = new LinkedList<string>();
        //
        // First add three elements to the linked list.
        //
        linked.AddLast("one");
        linked.AddLast("two");
        linked.AddLast("three");
        //
        // Insert a node before the second node (after the first node)
        //
        LinkedListNode<string> node = linked.Find("one");
        linked.AddAfter(node, "inserted");
        //
        // Loop through the linked list.
        //
        foreach (var value in linked)
        {
            Console.WriteLine(value);
        }
    }
}

--- Output of the program ---

one
inserted
two
three


***

Then, I follow their code and some error occur. Below is my code:-

using System;
using System.Collections.Generic;
using System.Collections;
using System.Linq;
using System.Text;

class Program
{
    public static void Main(string[] args)
    {
        LinkedList<addall1> addorder1 = new LinkedList<addall1>();

        string foodname1 = "kfr";

        addall1 a1 = new addall1(1, foodname1);
        addorder1.AddLast(a1);

        string foodname2 = "sfr";
        addall1 a2 = new addall1(1, foodname2);
        addorder1.AddLast(a2);

        string foodname3 = "tfr";
        LinkedListNode<addall1> node = addorder1.Find(foodname1);
        addorder1.AddAfter(node,(1,foodname3));

        foreach(addall1 ad1 in addorder1)
        {
            Console.WriteLine("Qty:" + ad1.Countb4sol + " Name:" + ad1.Llfdname1);
        }
        Console.ReadLine();
    }

    public class addall1
    {
        public addall1(int countb4sol1, string llfdname1)
        {
            _countb4sol1 = countb4sol1;
            _llfdname1 = llfdname1;
        }

        private int _countb4sol1;
        private string _llfdname1 = "";

        public int Countb4sol
        {
            get { return (_countb4sol1); }
            set { _countb4sol1 = value; }
        }

        public string Llfdname1
        {
            get { return (_llfdname1); }
            set { _llfdname1 = value; }
        }
    }
}

Error occur at line 23. Can someone help me... Thx n appreciate it...
The output should be:-

kfr
tfr
sfr

Finding code is easy but modifying it as per our requirements is the real skills..

using System;
using System.Collections.Generic;
using System.Collections;
using System.Linq;
using System.Text;

class Program
{
    public static void Main(string[] args) 
    { 
        LinkedList<addall1> addorder1 = new LinkedList<addall1>(); 
  
        string foodname1 = "kfr"; 
  
        addall1 a1 = new addall1(1, foodname1); 
        addorder1.AddLast(a1); 
  
        string foodname2 = "sfr"; 
        addall1 a2 = new addall1(1, foodname2); 
        addorder1.AddLast(a2); 
  
        string foodname3 = "tfr"; 
        LinkedListNode<addall1> node = addorder1.Find(a1);
        addorder1.AddAfter(node, new addall1(1, foodname3)); 
  
        foreach(addall1 ad1 in addorder1) 
        { 
            Console.WriteLine("Qty:" + ad1.Countb4sol + " Name:" + ad1.Llfdname1); 
        } 
        Console.ReadLine(); 
    }

    public class addall1
    {
        public addall1(int countb4sol1, string llfdname1)
        {
            _countb4sol1 = countb4sol1;
            _llfdname1 = llfdname1;
        }

        private int _countb4sol1;
        private string _llfdname1 = "";

        public int Countb4sol
        {
            get { return (_countb4sol1); }
            set { _countb4sol1 = value; }
        }

        public string Llfdname1
        {
            get { return (_llfdname1); }
            set { _llfdname1 = value; }
        }
    }
}

Hope you would do that carefully next time.
best of luck
