Solution 1

If your indexes are starting from 1 (Hashtable and Dictionary) your iteration variable should go util reaches the last element: j <= h.Count and k <= dict.Count respectively.

how to get all values including spaces?

Zoltán Zörgő 15-Sep-12 5:37am

I don't understand - what do you mean by "spaces"? If you change the two for statements as I suggested, you will get all values. And you will get two empty rows between them, since you added a Console.WriteLine() at the end of the methods, and between the calls also.

ya got the expected answer ... Thanku so much

Zoltán Zörgő 15-Sep-12 5:43am

This will also work:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;
 
namespace Array_List
{
    class Program
    {
        static void Main(string[] args)
        {
           Program pg = new Program();
            pg.HashTable();
           Console.WriteLine();
            pg.Dictionary();
           Console.WriteLine();
            pg.table();
           Console.ReadLine();
        } 
 
        public void HashTable()
        {
            Hashtable h = new Hashtable();
            h.Add(1, "Sunday");
            h.Add(2, "Monday");
            h.Add(3, "tuesday");
            h.Add(4, "Wednesday");
            h.Add(5, "Thursday");
            h.Add(6, "Friday");
            h.Add(7, "Saturday");
            foreach(DictionaryEntry s in h)
            {
            	Console.WriteLine(s.Value);
            }
        }
        
        public void Dictionary()
        {
            Dictionary<int,string> dict = new Dictionary<int,string>();
            dict.Add(1, "Jan");
            dict.Add(2, "Feb");
            dict.Add(3, "Mar");
            dict.Add(4, "Apr");
            dict.Add(5, "May");
            dict.Add(6, "June");
            dict.Add(7, "July");
            dict.Add(8, "Aug");
            dict.Add(9, "Sept");
            dict.Add(10, "Oct");
            dict.Add(11, "Nov");
            dict.Add(12, "Dec");
            foreach(KeyValuePair<int,string> s in dict)
            {
            	Console.WriteLine(s.Value);
            }
        }

        public void table()
        {
            ArrayList names = new ArrayList();
 
            names.Add("ARUL");
            names.Add("POO");
            names.Add("KAYAL");
            names.Add("MOM");
            names.Add("DAD");
            foreach(string s in names)
            {
            	Console.WriteLine(s);
            }
        }
    }
}

k sure sure... am eager to learn in alternative / new ways...

arul mozhi 15-Sep-12 6:02am

for hash table function if i use foreach loop , am getting the answer in reverse order.... y???

Solution 2

Use the foreach statement to iterate your collections, then there is no need to be concerned with indices.
