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
