上面是我读取PPT文本的代码，但是它是一行一行输出我想一个PPT一下读取，全部输出。。而不是一行一行。

Answer 1

 Console.WriteLine(text);
那你把这行代码放第二个for循环外面

Answer 2

加载引用Microsoft Power Point 12.0 object library 和morcosoft office12.0 object Library其中的数字是版本号，低点不要紧。代码：    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;
    }
