Can you show me an example : In form load, create label array and then add them to the form?

Accepted answer
OK, in that case the labels need to be such that you can set their properties in a loop:

static class Program
{
internal static int nLabels;

[STAThread]
static void Main()
{
nLabels = 2; // or whatever
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

// declare array at form level so can be accessed from anywhere in form
private Label[] labels;

private void Form1_Load(object sender, EventArgs e)
{
int n = Program.nLabels;
labels = new Label[n];

// create array elements in a loop
for (int i = 0; i < n; i++)
{
labels[i] = new Label();
labels[i].Text = "whatever " + (i + 1).ToString();
labels[i].Location = new Point(10, 30 * (i + 1)); // for example
// set other properties
}

// add them to the form's Controls collection
this.Controls.AddRange(labels);
}

// other methods
}

Yes, that is exactly what I need and is a perfect answer!

Thank you for quick response.
I didn't make my question clearly.
I need to designed the size of the label array nLabels in main() and then create the label array of Program.nLabels in the form load, some kind of dynamically.

Sure, this should do it.

For illustation I've just created an array with 2 labels but it can, of course, have as many as you like.

// declare array at form level so it can be accessed from anywhere in form

private Label[] labels;

private void Form1_Load(object sender, EventArgs e)
{
// create individual labels

Label label1 = new Label();
label1.Text = "whatever 1";
// set Location and any other properties

Label label2 = new Label();
label2.Text = "whatever 2";
// set Location and any other properties

// add them to array and thence to the form's Controls collection

labels = new Label[2]{label1, label2};
this.Controls.AddRange(labels);
}
