	//

	ArrayList list = new ArrayList();

	list.Add(3);

	list.Add(4);

	//

	// Second ArrayList.

	//

	ArrayList list2 = new ArrayList();

	list2.Add(5);

	list2.Add(6);

	//

	// Add second ArrayList to first.

	//

	list.AddRange(list2);

	//

	// Display the values.

ArrayList list = new ArrayList();
list.Add("rajan");
list.Add(20000);
string[] stringList = list.OfType<string>().ToArray();
Int32[] intList = list.OfType<Int32>().ToArray();
int n1 = intList[0];
Console.WriteLine(n1);

output :20000

//First of all create an object for the ArrayList Class

// Creates and initializes a new ArrayList.
ArrayList myAL = new ArrayList();
myAL.Add( "My" );
myAL.Add( "Name" );
myAL.Add( "is" );
myAL.Add( "Srinivas" );
//Now once the list is created try to display the list
foreach (string val in myAL)
{
Console.WriteLine(val);
}
