How can I access the column-index value of an element whose aria-label I know using Selenium web driver in c#

I want to access the aria-colindex value of an element using the aria-label value, how can I do this in the cleanest way using selenium or c#

driver.FindElement(By.XPath("//td[@aria-label='Sütun Stok']"));

<td aria-selected="false" role="columnheader" aria-colindex="3" id="dx-col-95" aria-label="Sütun Stok" class="dx-datagrid-action dx-cell-focus-disabled dx-datagrid-drag-action" aria-sort="none" tabindex="0" style="text-align: left; min-width: 45px; max-width: 250px; width: 250px;" xpath="1"><div class="dx-column-indicators" role="presentation" style="float: right;"><span class="dx-sort dx-sort-none"></span></div><div class="dx-datagrid-text-content dx-text-content-alignment-left" role="presentation" title="Stok">Stok</div></td>
