Access word checkboxlist and check if check mark in checkbox

问题

I have a button that creates checkedlistbox inside a table in word. the problem is that I can access the checkedlistbox only inside the function and if I am doing this inside the scope, I can only access the last checkedlistbox

the code:

{
    Microsoft.Office.Tools.Word.Controls.CheckedListBox listBox1;
    Document extendedDocument = Globals.Factory.GetVstoObject(Globals.ThisAddIn.Application.ActiveDocument);
    extendedDocument.Paragraphs[1].Range.InsertParagraphBefore();
    listBox1 = extendedDocument.Controls.AddCheckedListBox(newTable.Cell(i , 2).Range, 90, 66.75F, "checkedListBox1" + i);
    //listBox1.Name = xlDDLRange.Cells[j, i].Value2.ToString();
    // MessageBox.Show(listBox1.Name);
    //CheckedListBox.CheckedItemCollection;
    listBox1.IntegralHeight = true;
    int j = 1;
    int range = ColumnRange(i );

    while (true)
    {
        //MessageBox.Show(xlDDLRange.Cells[j, i].Value2.ToString());
        if (j == range) break;
        // Add items that are wide to the ListBox.
        listBox1.Items.Add(xlDDLRange.Cells[j+1 , i ].Value2.ToString());
        j++;
    }
}

and the code to check if check is mark:

foreach (Microsoft.Office.Tools.Word.Controls.CheckedListBox listBox1 in listBox)
{
    MessageBox.Show(listBox1.Name);
    foreach (int indexChecked in listBox1.CheckedIndices)
    {
        MessageBox.Show(indexChecked.ToString());
        // The indexChecked variable contains the index of the item.
        MessageBox.Show("Index#: " + indexChecked.ToString() + ", is checked. Checked state is:" +
                        listBox1.GetItemCheckState(indexChecked).ToString() + ".");
    }
}

please help :(
