Why will this line not fire??

Question

I am new to the C# language and for the life of me I cannot figure out why this line will not fire when the three array tags match. Can someone help me out?

 

if ((btn[0].Tag == btn[1].Tag) && (btn[1].Tag == btn[2].Tag))
{
//DisplayTheWinner()
btn[0].BackColor = Color.Red;
btn[1].BackColor = Color.Red;
btn[2].BackColor = Color.Red;
 

Thank you,
