how to retrieve arraylist items in reverse order
Suppose the arrayList stores data in a particular order, and to retrieve data in a reverse order we use Reverse() method. The below code demonstrates how to display data in a reverse order.
private void Form1_Load(object sender, EventArgs e) { // ArrayList contains Customer names ArrayList arrayList = new ArrayList(); arrayList.Add("Customer1"); arrayList.Add("Customer2"); arrayList.Add("Customer3"); arrayList.Add("Customer4"); arrayList.Add("Customer5"); //reversing the array arrayList.Reverse(); string str = string.Empty; foreach (string strName in arrayList) { str += strName + "\n"; } string str = string.Empty; for (int i = arrayList.Count - 1; i >= 0; i--) { str += arrayList[i].ToString() + "\n"; }
