        </Style>

        <!--DataGrid单元格内容居中-->
        <Style x:Key="DataGridCellStyle" TargetType="DataGridCell">
            <Setter Property="HorizontalAlignment" Value="Center"/>
            <Setter Property="VerticalAlignment" Value="Center"/>
        </Style>

                </Setter.Value>
            </Setter>
        </Style>

每一行添加序号

1，在XAML页面中的DataGrid中添加一列

 <DataGridTextColumn Header="序号" Width="*" Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type DataGridRow}}, Path=Header}"  CellStyle="{StaticResource DataGridCellStyle}"/>

2，在DataGrid上添加一个LoadingRow事件，该事件的处理方法如下

        private void DataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
        {
            e.Row.Header = e.Row.GetIndex() + 1;
        }
