SortedList in .Net

here is an example of Sorted list in C#.net



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

namespace ConsoleApps
{
public class ClsSortedList
{
// create a SortedList object
SortedList mySortedList = new SortedList();

// add elements containing US state abbreviations and state
// names to mySortedList using the Add() method
public void MainFunction()
{
mySortedList.Add("NY", "New York");
mySortedList.Add("FL", "Florida");
mySortedList.Add("AL", "Alabama");
mySortedList.Add("WY", "Wyoming");
mySortedList.Add("CA", "California");

// display the keys for mySortedList using the Keys property
foreach (string myKey in mySortedList.Keys)
{
Console.WriteLine("myKey = " + myKey);
}

// display the values for mySortedList using the Values property
foreach (string myValue in mySortedList.Values)
{
Console.WriteLine("myValue = " + myValue);
}

// use the ContainsKey() method to check if mySortedList
// contains the key "FL"
if (mySortedList.ContainsKey("FL"))
{
Console.WriteLine("mySortedList contains the key FL");
}

// use the ContainsValue() method to check if mySortedList
// contains the value "Florida"
if (mySortedList.ContainsValue("Florida"))
{
Console.WriteLine("mySortedList contains the value Florida");
}

// use the Remove() method to remove FL from mySortedList
Console.WriteLine("Removing FL from mySortedList");
mySortedList.Remove("FL");

// get the key at index 3 using the GetKey() method
string keyAtIndex3 = (string)mySortedList.GetKey(3);
Console.WriteLine("The key at index 3 is " + keyAtIndex3);

// get the index of the element with the key "NY"
// using the IndexOfKey() method
int myIndex = mySortedList.IndexOfKey("NY");
Console.WriteLine("The index of NY is " + myIndex);

// get the index of the element with the value "New York"
// using the IndexOfValue() method
myIndex = mySortedList.IndexOfValue("New York");
Console.WriteLine("The index of New York is " + myIndex);

// replace the value of the element at myIndex with "New York State"
// using the SetByIndex() method
Console.WriteLine("Replacing the value New York with New York State");
mySortedList.SetByIndex(myIndex, "New York State");

// get the key list using the GetKeyList() method
Console.WriteLine("Getting the key list");
IList myKeyList = mySortedList.GetKeyList();
foreach (string myKey in myKeyList)
{
Console.WriteLine("myKey = " + myKey);
}

// get the value list using the GetValueList() method
Console.WriteLine("Getting the value list");
IList myValueList = mySortedList.GetValueList();
foreach (string myValue in myValueList)
{
Console.WriteLine("myValue = " + myValue);
}
}
}
}
