//Dictionary
System.Collections.DictionaryEntry dic=new System.Collections.DictionaryEntry("key1","value1");

//ArrayList
System.Collections.ArrayList list=new System.Collections.ArrayList();
list.Add(1);
list.Add(2);
for(int i=0;i{
System.Console.WriteLine(list[i]);
}

//HashTable
System.Collections.Hashtable table=new System.Collections.Hashtable();
table.Add("table1",1);
table.Add("table2",2);
System.Collections.IDictionaryEnumerator d=table.GetEnumerator();
while(d.MoveNext())
{
System.Console.WriteLine(d.Entry.Key);
}

//Queue
System.Collections.Queue queue=new System.Collections.Queue();
queue.Enqueue(1);
queue.Enqueue(2);

System.Console.WriteLine(queue.Peek());
while(queue.Count>0)
{
System.Console.WriteLine(queue.Dequeue());
}

//SortedList
System.Collections.SortedList list=new System.Collections.SortedList();
list.Add("key2",2);
list.Add("key1",1);
for(int i=0;i{
System.Console.WriteLine(list.GetKey(i));
}

//Stack
System.Collections.Stack stack=new System.Collections.Stack();
stack.Push(1);
stack.Push(2);

System.Console.WriteLine(stack.Peek());
while(stack.Count>0)
{
System.Console.WriteLine(stack.Pop());
}
