Suppose you add a couple of buttons to a panel as shown below. What do you think the message in the MessageBoxes will be?
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
for (int i = 0; i < 10; ++i)
{
Button button = new Button();
button.Text = String.Format("{0:00}", i);
this.flowLayoutPanel1.Controls.Add( button );
button.Click += new EventHandler(delegate(Object sender, EventArgs e)
{
MessageBox.Show(String.Format("You clicked button {0:00}", i));
});
}
}
}
In case you’re wondering why they all have the message “You clicked button 10” i suggest you read the following articles
