如何读取ppt内容

1、java版本

public string PptReader(string filename)

{

string fullname = DocPath+filename; //绝对路径

PowerPoint.Application papp = new PowerPoint.Application();

PowerPoint.Presentation ppr = papp.Presentations.Open(fullname, Microsoft.Office.Core.MsoTriState.msoCTrue,

MsoTriState.msoFalse, MsoTriState.msoFalse);

string doc = "";

foreach (PowerPoint.Slide slide in ppr.Slides)

{

foreach (PowerPoint.Shape shape in slide.Shapes)

{

if (shape.HasTextFrame. == MsoTriState.msoTrue)

{

if (shape.TextFrame.HasText == MsoTriState.msoTrue)

{

doc += shape.TextFrame.TextRange.Text.ToString();

doc += "/n";

}

}

}

}

ppr.Close();

System.Runtime.InteropServices.Marshal.ReleaseComObject(ppr);

ppr = null;

papp.Quit();

System.Runtime.InteropServices.Marshal.ReleaseComObject(papp);

papp = null;

return doc;

}
