Question

I have a array of checkboxes, 33 in total.
Because the checkboxes are all over the page, it needs to be in an array (right?).

The code-behind looks like this:

CheckBox[] variableName = new CheckBox[33];

        variableName[0] = idCheckBox1;
        variableName[1] = idCheckBox1;
        variableName[2] = idCheckBox1;
        variableName[3] = idCheckBox1;

and so on…

ASP.NET:

<asp:CheckBox ID="idCheckBox1" runat="server" Value="1" />
<asp:CheckBox ID="idCheckBox2" runat="server" Value="2" />
...

The checkboxes are totally optional.
Now how do i get the value of the checked boxes only in a variable?

It does NOT need to be an array.
This is how you get all the CHECKED checkboxes in your form from the CodeBehind:

var names = formCollection.AllKeys.Where(c => 
                    c.StartsWith("idCheckBox") && 
                    formCollection.GetValue(c) != null &&
                    formCollection.GetValue(c).AttemptedValue == "1");
