ArrayList Working (C#.net)

The following code shows you working with arraylist.

// Declaring An ArrayList

  ArrayList aryList = new ArrayList();

// Adding objects in arrayList

  aryList.Add("Osama");

  aryList.Add("Mursleen");

  aryList.Add("Maverick");

  aryList.Add("Veracious");

  aryList.Add("Mascot");

// Displaying arrayList elements

   foreach (string o in aryList)

      Console.WriteLine((o));

// Displaying itmes count in arraylist (Displays 5 items)

   Console.WriteLine("The ArrayList Has " + aryList.Count + " Items");

 

// In this way we can also add elements in arrayList

   aryList.AddRange(new string[] {"Hello", "world", "this", "is", "a", "test"});

        

// Displaying itmes count in arraylist (Now , Displays 11 items)

   Console.WriteLine("The ArrayList Has " + aryList.Count + " Items");

         

// Reverse arrayList elements

   aryList.Reverse();

// Searching an object in arrayList and returns its location

   Console.WriteLine(aryList.BinarySearch("this"));

// Checking whether specified object is in arrayList or not?

   if (aryList.Contains("a"))

   {

      Console.WriteLine("Element In ArrayList");

   }

// Removes the first occurence of the specified object

   aryList.Remove("test");

// Removes the element at specified index starting from 0th index

   aryList.RemoveAt(3);

// Removes a range of elements from 1 to 3

   aryList.RemoveRange(1, 3);

// Clear the arrayList

   aryList.Clear();
