What is the result of the following code?



 ArrayList intList = new ArrayList();

 string strOutput = "";



 intList.Add( 1 );

 intList.Add( 3 );

 intList.Add( 5 );



 foreach ( int intListItems in intList )

 {

 strOutput += ( " " + intListItems.ToString() );

 }



 MessageBox.Show( strOutput, "Mystery",

 MessageBoxButtons.OK, MessageBoxIcon.Information );

This code creates an ArrayList and adds to it the values 1, 3 and 5. The values are

then appended to each other (separated by spaces) using a foreach statement, and the result is displayed in a MessageBox. The complete code reads:




 // MessageBox.cs





 using System;


 using System.Drawing;


 using System.Collections;


 using System.ComponentModel;


 using System.Windows.Forms;


 using System.Data;





 namespace MessageBoxes


 {


 /// 


 /// Summary description for FrmMessageBox.


 /// 



 public class FrmMessageBox : System.Windows.Forms.Form


 {


 private System.Windows.Forms.Label lblOutputOut;


 private System.Windows.Forms.Label lblOutput;





 /// 


 /// Required designer variable.


 /// 



 private System.ComponentModel.Container components = null;





 public FrmMessageBox()


 {


 //


 // Required for Windows Form Designer support


 //


 InitializeComponent();





 //


 // TODO: Add any constructor code after InitializeComponent


 // call


 //


 }





 /// 


 /// Clean up any resources being used.


 /// 



 protected override void Dispose( bool disposing )


 {


 if( disposing )


 {


 if (components != null)


 {


 components.Dispose();


 }


 }


 base.Dispose( disposing );


 }





 // Windows Form Designer generated code





 /// 


 /// The main entry point for the application.

 {


 Application.Run( new FrmMessageBox() );


 }





 private void FrmMessageBox_Load(


 object sender, System.EventArgs e )


 {


ArrayList intList = new ArrayList();


string strOutput = "";


intList.Add( 1 );


intList.Add( 3 );


intList.Add( 5 );


foreach ( int intListItems in intList )


{


strOutput += ( " " + intListItems.ToString() );


}


MessageBox.Show( strOutput, "Mystery",


MessageBoxButtons.OK, MessageBoxIcon.Information );





 } // end method FrmMessageBox_Load





 } // end class FrmMessageBox
