Aspose.Slides
开发人员经常需要从演示文稿中提取文本。为此，需要从演示文稿中所有幻灯片的所有形状提取文本。本文介绍如何使用 Aspose.Slides 从 Microsoft PowerPoint PPTX 演示文稿中提取文本。无论是从单个幻灯片还是整个演示文稿提取文本，Aspose.Slides 都使用 PresentationScanner 类及其公开的静态方法。这些内容都归于命名空间 Aspose.Slides.Util。
string FilePath = @"..\..\..\..\Sample Files\";
string FileName = FilePath + "Move a Paragraph from One Presentation to Another 1.pptx";
string DestFileName = FilePath + "Move a Paragraph from One Presentation to Another 2.pptx";
MoveParagraphToPresentation(FileName, DestFileName);
// Moves a paragraph range in a TextBody shape in the source document
// to another TextBody shape in the target document.
public static void MoveParagraphToPresentation(string sourceFile, string targetFile)
{
string Text = "";
//Instantiate Presentation class that represents PPTX//Instantiate Presentation class that represents PPTX
Presentation sourcePres = new Presentation(sourceFile);
//Access first shape in first slide
IShape shp = sourcePres.Slides[0].Shapes[0];
if (shp.Placeholder != null)
{
//Get text from placeholder
Text = ((IAutoShape)shp).TextFrame.Text;
((IAutoShape)shp).TextFrame.Text = "";
}
Presentation destPres = new Presentation(targetFile);
//Access first shape in first slide
IShape destshp = sourcePres.Slides[0].Shapes[0];
if (destshp.Placeholder != null)
{
//Get text from placeholder
((IAutoShape)destshp).TextFrame.Text += Text;
}
sourcePres.Save(sourceFile, Aspose.Slides.Export.SaveFormat.Pptx);
destPres.Save(targetFile, Aspose.Slides.Export.SaveFormat.Pptx);
}
