//--需要遍历的列
var cols = dataGrid1.Columns[2];

foreach (var item in dataGrid1.ItemsSource)
{
  //--数据源的实体对象
                B_ExContents contets = item as B_ExContents;
              
                //--对象所在的单元格
                var cells = cols.GetCellContent(item);
                if (cells != null)
                {
             //--单元格所包含的元素
                    TextBox txt = cells as TextBox;
                   
                }
}
