Whats wrong with my code?

Question

I'm trying to make a label change text and color based on whether my application can detect an active internet connection.

private void lblConnection_Click(object sender, EventArgs e)
        {
            bool ConnCheck = System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable();
            if (ConnCheck == true)
            {
                lblConnection.Text = "Available";
                lblConnection.ForeColor = Color.LimeGreen;
            }
            else
            {
                lblConnection.Text = "Unavailable";
                lblConnection.ForeColor = Color.Red; 
            }//End Conncheck if statement//
        }//End lblConnection Class//


I would also like to make the application watch this connection dynamically and update the label as things change.
