WPF DataGrid：如何在 DataGrid 中迭代以获取行和列？

我有一个WPF DataGrid. 我想cells在Datagrid. 给我一个简单的代码来做到这一点。像这样

for(int i =0 ....) //rows
{
    for(int j=0 ....) //columns
    {
        //access cell
    }
}

 public IEnumerable<Microsoft.Windows.Controls.DataGridRow> GetDataGridRows(Microsoft.Windows.Controls.DataGrid grid)
 {
     var itemsSource = grid.ItemsSource as IEnumerable;
     if (null == itemsSource) yield return null;
     foreach (var item in itemsSource)
     {
        var row = grid.ItemContainerGenerator.ContainerFromItem(item) as Microsoft.Windows.Controls.DataGridRow;
                if (null != row) yield return row;
      }
 }

//假设网格绑定到一些信息类的可观察集合

foreach (DataGridRow rowContainer  in GetDataGridRows(gridname))
{
  if (rowContainer != null)
  {
     DataGridCellsPresenter presenter = GetVisualChild<DataGridCellsPresenter>(rowContainer);

     DataGridCell cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
     if (cell == null)
     {
        dataGrid1.ScrollIntoView(rowContainer, dataGrid1.Columns[column]);
        cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
      }

      //start work with cell
  }
}
