说明（2017-8-1 11:15:46）：
1. 哈哈，我就说微软肯定有自己的办法，把PPT转成图片。
2. 主要是要引入两个微软自己的程序集，vs里自带直接添加引用，注意一下版本，12.0是office2007吧？反正我用的14.0的。
添加完会多出来两个引用：
3. 剩下的看代码就可以了，非常之简单，核心代码就三行！
4. 感谢下面的参考资料：

另外*是个好东西：

还有必应搜索，不知道比百度强到哪里去了，添加程序集的时候遇到几个问题，都是在必应里搜索到解决办法的：
xaml：
<Window x:Class="PPT2JPG.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="" Width="">
<Grid>
<Button Content="开始转成图片" HorizontalAlignment="Left" Height="" Margin="366,181,0,0" VerticalAlignment="Top" Width="" Click="Button_Click_1"/>
<Label Content="PPT路径" HorizontalAlignment="Left" Height="" Margin="46,69,0,0" VerticalAlignment="Top" Width=""/>
<TextBox Name="txtBoxPath" HorizontalAlignment="Left" Height="" Margin="129,66,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width=""/>
</Grid>
</Window>
