HashTable Storing multiple Values in Single Key

Question

Hi,

I want to store multiple values in single key and i'm using this logic

Hashtable ht = new Hashtable(); 

int[] intArr = new Integer[2]; 

intArr [0] = 10;

intArr [1] = 11;

ht.Add("1","intArr");

but i don't know how to retrieve or fetch the value from it 

i want something like this

ht[1].intArr[1],ht[1].intArr[2]

Please help me out guys.

Regards
