Pushing text value of a checkbox in an array

I have two checkboxes like :

<div>
    <asp:CheckBox ID="CheckBox1" runat="server" Checked="true" Text="Status"/>
    </div>
    <div>
    <asp:CheckBox ID="CheckBox2" runat="server" Checked="true" Text="FirstName"/>
    </div>

I have an array like

string[] arrchk = new string[] { };

How can I store the text value of the checkboxes in the array
