使用WPF dataGrid进行复制和粘贴

<DataGrid x:Name="myDataGrid" CanUserAddRows="False" CanUserDeleteRows="False" ClipboardCopyMode="IncludeHeader" />

using System.Windows;
using System.Windows.Controls;

private void CopyCommand_Executed(object sender, RoutedEventArgs e)
{
    if (myDataGrid.SelectedCells.Count > 0)
    {
        DataGridCellInfo cellInfo = myDataGrid.SelectedCells[0];
        if (cellInfo != null && cellInfo.Item != null)
        {
            Clipboard.SetData(DataFormats.Text, ((DataGridCell)cellInfo.Column.GetCellContent(cellInfo.Item)).Content.ToString());
        }
    }
}

private void PasteCommand_Executed(object sender, RoutedEventArgs e)
{
    if (myDataGrid.SelectedCells.Count > 0)
    {
        DataGridCellInfo cellInfo = myDataGrid.SelectedCells[0];
        if (cellInfo != null && cellInfo.Item != null)
        {
            var content = Clipboard.GetData(DataFormats.Text);
            if (content != null)
            {
                ((DataGridCell)cellInfo.Column.GetCellContent(cellInfo.Item)).Content = content.ToString();
            }
        }
    }
}

<Button Content="Copy" Command="Copy" Click="CopyCommand_Executed" />
