two list in the hash table

List str1=new List();
str1.Add("a");
str1.Add("b");

List str2=new List();
str1.Add("apple");
str1.Add("ball");

Hashtable ht = new Hashtable();
ht.Add(str1, str2);

can i check str1 is equal to from the previous page list And display the str2 value as result.

Well, you can do this:

using System;

using System.Collections;

using System.Collections.Generic;

class Test

{

static void Main()

{

List str0 = new List();

str0.Add("a");

str0.Add("b");

List str1 = new List();

str1.Add("a");

str1.Add("b");

List str2=new List();

str2.Add("apple");

str2.Add("ball");

Hashtable ht = new Hashtable();

ht.Add(str1, str2);

// check if str0 and str1 contain the same elements in the same order

bool isSame = true;

if(str0.Count != str1.Count)

{

isSame = false;

}

else

{

for(int i = 0; i < str0.Count; i++)

{

string e0 = (string)str0[i];

string e1 = (string)str1[i];

if (e0 != e1)

{

isSame = false;

break;

}

if (isSame)

{

foreach(string s in (List)ht[str1])

{

Console.WriteLine(s);

}

else

{

Console.WriteLine("str0 and str1 are not the same");

}

Console.ReadKey();

}

}

The output is:

apple

ball
