WPF中 根据Excel模版导出数据到Excel

前台.xaml文件:

<Window x:Class="Export.MainWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        Title="MainWindow" Height="350" Width="525">    <Grid>        <Button Content="Export" Height="44" HorizontalAlignment="Left" Margin="193,107,0,0" Name="button1" VerticalAlignment="Top" Width="100" Click="button1_Click" />        <TextBox Height="23" HorizontalAlignment="Left" Margin="24,22,0,0" Name="textBox1" VerticalAlignment="Top" Width="322" />        <Button Content="Choose Stencil File" Height="23" HorizontalAlignment="Left" Margin="360,22,0,0" Name="button2" VerticalAlignment="Top" Width="131" Click="button2_Click" />    </Grid></Window>
