Arrays (Cont.)

An Example (Cont.)

The following program is the implementation of the example:

 using System;
 using System.Windows.Forms;

 namespace WindowsFormsApp2 {
   public partial class Array : Form {
     public Array( ) { InitializeComponent( ); }

     private void addName( ) {
       string[ ] studentName = new string[5];
       for ( int i = 0; i < 5; i++ ) {
          studentName[i] = Microsoft.VisualBasic.Interaction.InputBox( 
            "Enter the student name:" );
          nameList.Items.Add( studentName[i] );
       }
     }
     private void Start_Click( object sender, EventArgs e ) {
       nameList.Items.Clear( );
       addName( );
     }
     private void Exit_Click( object sender, EventArgs e ) {
       Application.Exit( );
     }
   }
 }

The ListBox control displays a list from which the user can select one or more items.

The ListBox.Items property gets the items of the ListBox.

The ListBox.Items.Add method adds an item to the list of items for a ListBox.

The ListBox.Items.Clear method removes all items from the list.

In order to make the VB InputBox Microsoft.VisualBasic.Interaction.InputBox work for C#, add the Microsoft.VisualBasic by using the Reference Manager:

Right click the project WindowsFormsApp2 in the Visual Studio,
Select the option Add, and
Select the option Reference....
