This is a sample code I wrote to add some tab pages with the controls in them at run time. but when I run it , I get a Null Ref exception error. what part I am doing wrong?

TabPage[] tabPages = new TabPage[2];

CheckBox ck  = new CheckBox();

 

    tabPages[0].BackColor = Color.Firebrick;

    tabPages[0].Controls.Add(ck);

 

    tabPages[1].BackColor = Color.Firebrick;

    tabPages[1].Controls.Add(ck);

 

tabGuy.SuspendLayout();

    tabGuy.TabPages.Add(tabPages[0]);

    tabGuy.TabPages.Add(tabPages[1]);

tabGuy.ResumeLayout();
