Key Value pair in C#.net

The basic code to do that would be as follows:

using System;

using System.IO;

using System.Collections;

class Program

{

static void Main()

{

string[] lines = File.ReadAllLines("tvfun.txt");

Hashtable htk = new Hashtable();

foreach(string line in lines)

{

string[] items = line.Split('=');

htk.Add(items[0], int.Parse(items[1]));

}

while(true)

{

Console.WriteLine("Enter any Command or q to quit");

string key = Console.ReadLine().ToUpper();

if (key == "Q") return;

if (htk.ContainsKey(key))

{

Console.WriteLine("A key of '{0}' corresponds to a value of {1}\n", key, htk[key]);

}

else

{

Console.WriteLine("The key '{0}' does not exist in the file\n", key);

}
