如何在WPF Datagrid中实现复制

Question

I am trying to implement a Copy operation for a datagrid configured with

SelectionMode="Extended"
SelectionUnit="Cell"

I have figured out (mostly) how to get content from the cells in the DataGrid.SelectedCells collection - Text columns, Combobox columns, and Templated columns. Determining how many columns are involved seems pretty straightforward:

var cols = selectedCells.Select(c => c.Column.DisplayIndex).Distinct().ToList();
Debug.WriteLine($"Found {cols.Count} columns.");

However, I can't figure out if the cells are on different rows. I think I need that information to use appropriate separators between cells to indicate multiple rows. DataGrid.SelectedCells is an

IList<DataGridCellInfo>

The DataGridCellInfo has an

object Item

property, which is an item in the collection the datagrid is bound to. I don't think that helps...

Any ideas or pointers would be appreciated, thanks.

您应该能够使用DataGrid.Items.IndexOf(cell.Item)检索行索引，其中cell是DataGridCellInfo
