Copy the elements of collection over a range of elements in ArrayList in C#

To copy the elements of the collection over a range of elements in ArrayList, the code is as follows −

Example

 Live Demo

using System; using System.Collections; public class Demo {    public static void Main(){       ArrayList arrList = new ArrayList();       arrList.Add("A");       arrList.Add("B");       arrList.Add("C");       arrList.Add("D");       Console.WriteLine("ArrayList elements...");       for (int i = 0; i < arrList.Count; i++) {          Console.WriteLine("" + arrList[i]);       }       string[] str = { "Demo", "Text" };       arrList.SetRange(0, str);       Console.WriteLine("After copying...");       for (int i = 0; i < arrList.Count; i++) {          Console.WriteLine("" + arrList[i]);       }    } }

Output

This will produce the following output −

ArrayList elements... A B C D After copying... Demo Text C D

Example

Let us now see another example −

 Live Demo

using System; using System.Collections; public class Demo {    public static void Main(){       ArrayList arrList = new ArrayList();       arrList.Add("One");       arrList.Add("Two");       arrList.Add("Three");       arrList.Add("Four");       arrList.Add("Five");       arrList.Add("Six");       arrList.Add("Seven");       arrList.Add("Eight");       Console.WriteLine("ArrayList elements...");       for (int i = 0; i < arrList.Count; i++) {          Console.WriteLine("" + arrList[i]);       }       string[] str = { "Demo", "Text" };       arrList.SetRange(2, str);       Console.WriteLine("After copying...");       for (int i = 0; i < arrList.Count; i++) {          Console.WriteLine("" + arrList[i]);       }    } }

Output

This will produce the following output −

ArrayList elements... One Two Three Four Five Six Seven Eight After copying... One Two Demo Text Five Six Seven Eight
