C#学习笔记(24)——C#将PPT批量转为JPG(最简单的方法)
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stackoverflow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="350" Width="525"> <Grid> <Button Content="开始转成图片" HorizontalAlignment="Left" Height="40" Margin="366,181,0,0" VerticalAlignment="Top" Width="103" Click="Button_Click_1"/> <Label Content="PPT路径" HorizontalAlignment="Left" Height="32" Margin="46,69,0,0" VerticalAlignment="Top" Width="77"/> <TextBox Name="txtBoxPath" HorizontalAlignment="Left" Height="35" Margin="129,66,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="354"/> </Grid> </Window>
