public class Form1 : System.Windows.Forms.Form
{
    private TabControl tabControl1;
    private TabPage tabPage1;
    private TabPage tabPage2;
    private Button button1;
    private Button button2;

    private void InitializeMyTabs()
    {
        tabControl1 = new System.Windows.Forms.TabControl();
        tabPage1 = new System.Windows.Forms.TabPage();
        tabPage2 = new System.Windows.Forms.TabPage();
        button1 = new System.Windows.Forms.Button();
        button2 = new System.Windows.Forms.Button();

        tabControl1.Controls.AddRange(new System.Windows.Forms.Control[] {
            tabPage1,
            tabPage2});
        tabControl1.Location = new System.Drawing.Point(40, 24);
        tabControl1.Size = new System.Drawing.Size(216, 216);
        tabControl1.TabIndex = 0;

        tabPage1.Controls.AddRange(new System.Windows.Forms.Control[] {button1});
        tabPage1.TabIndex = 0;
        tabPage2.Controls.AddRange(new System.Windows.Forms.Control[] {button2});
        tabPage2.TabIndex = 1;

        button1.Location = new System.Drawing.Point(64, 72);
        button2.Location = new System.Drawing.Point(64, 72);
        button2.Text = "button2";

        ClientSize = new System.Drawing.Size(292, 273);
        Controls.AddRange(new System.Windows.Forms.Control[] {tabControl1});

        // Gets the index of the TabPage containing button2.
        // Selects the index of the TabPage containing button2. 
        tabControl1.SelectedIndex = (TabPage.GetTabPageOfComponent(button2)).TabIndex;
    }

    public Form1()
    {
        InitializeMyTabs();
    }

    static void Main() 
    {
        Application.Run(new Form1());
    }
}
