C＃动态复选框“已选中”

Question

I have a for loop to send 5 dynamically created textboxes to a row in Excel. This function works perfect but...I also have a checkbox that is created with each row and is currently ignored. I want to add this checkbox to my function. I only want the dynamic rows that have the checkbox selected to go to Excel. Below is my existing for loop code. This is the name of the checkbox (""chkAddItem")

 for (int CheckRow = 0; CheckRow < addOnRows; CheckRow++)
        {                                                   //add addOn rows to spreadsheet
            worksheet.Rows[StartAddOn].Insert();
            worksheet.Cells[StartAddOn, "D"].value = srcAddOnPanel.Controls["txtQtyAddOn" + CheckRow].Text;
            worksheet.Cells[StartAddOn, "E"].value = srcAddOnPanel.Controls["txtProductNameAddOn" + CheckRow].Text;
            worksheet.Cells[StartAddOn, "F"].value = srcAddOnPanel.Controls["txtListPriceAddOn" + CheckRow].Text;
            worksheet.Cells[StartAddOn, "G"].value = srcAddOnPanel.Controls["txtMaxDiscountAddOn" + CheckRow].Text;
            worksheet.Cells[StartAddOn++, "H"].value = srcAddOnPanel.Controls["txtProposedPriceAddOn" + CheckRow].Text;
        }

Like this?

for (int checkRow = 0; checkRow < addOnRows; checkRow++)
{      
   if (((CheckBox)srcAddOnPanel.Controls["chkAddItem" + checkRow]).Checked)
   {                                     
      //add addOn rows to spreadsheet
      worksheet.Rows[StartAddOn].Insert();
      worksheet.Cells[StartAddOn, "D"].value = srcAddOnPanel.Controls["txtQtyAddOn" + checkRow].Text;
      worksheet.Cells[StartAddOn, "E"].value = srcAddOnPanel.Controls["txtProductNameAddOn" + checkRow].Text;
      worksheet.Cells[StartAddOn, "F"].value = srcAddOnPanel.Controls["txtListPriceAddOn" + checkRow].Text;
      worksheet.Cells[StartAddOn, "G"].value = srcAddOnPanel.Controls["txtMaxDiscountAddOn" + checkRow].Text;
      worksheet.Cells[StartAddOn++, "H"].value = srcAddOnPanel.Controls["txtProposedPriceAddOn" + checkRow].Text;
   }
}
