我正在获取 ppt 文件幻灯片中的所有形状现在我想从这些形状中获取文本我该怎么做

这是我的方法，我在 ppt 文件中获取所有幻灯片的形状

public void Main(string[] args)
    {
        // The path to the documents directory.
        string dataDir = Path.GetFullPath(@"C:\Users\Vipin\Desktop\");
        //Load the desired the presentation
        Presentation pres = new Presentation(dataDir + "Android.ppt");
        using (Presentation prestg = new Presentation(dataDir + "Android.ppt"))
        {


            //Accessing a slide using its slide index
            int slideCount = prestg.Slides.Count();
            for (int i = 0; i <= slideCount - 1; i++)
            {
                ISlide slide = pres.Slides[i];
                foreach (IShape shap in slide.Shapes)
                {
                    int slideCountNumber = i + 1;

                    float shapeHeight = shap.Frame.Height;
                    float shapeWidth = shap.Frame.Width;
                    Debug.Write("slide Number: " + slideCountNumber + " shape width = " + shapeWidth + " shapeHeight = " + shapeHeight);

                }
            }

        }
    }

现在我可以从中获取文本吗

aspose will give u truncated text if u don't have the license of it. so it will be better for you if you will use Microsoft.Office.Interop.PowerPoint

use as below

public void ReadSlide(){

        string filePath= @"C:\Users\UserName\Slide.pptx";

        Microsoft.Office.Interop.PowerPoint.Application PowerPoint_App = new Microsoft.Office.Interop.PowerPoint.Application();
        Microsoft.Office.Interop.PowerPoint.Presentations multi_presentations = PowerPoint_App.Presentations;
        Microsoft.Office.Interop.PowerPoint.Presentation presentation = multi_presentations.Open(filePath, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);

        string presentation_textforParent = "";
        foreach (var item in presentation.Slides[1].Shapes)
        {
            var shape = (Microsoft.Office.Interop.PowerPoint.Shape)item;
            if (shape.HasTextFrame == MsoTriState.msoTrue)
            {
                if (shape.TextFrame.HasText == MsoTriState.msoTrue)
                {
                    var textRange = shape.TextFrame.TextRange;
                    var text = textRange.Text;

                    presentation_textforParent += text + " ";
                }
            }
        }

}

您可能不想从所有形状中提取文本，而是从文本框架中提取文本。为此，请使用类GetAllTextFrames公开的静态方法PresentationScanner

using (Presentation prestg = new Presentation(dataDir + "Android.ppt"))
{
   //Get an Array of ITextFrame objects from all slides in the PPTX
   ITextFrame[] textFramesPPTX = Aspose.Slides.Util.SlideUtil.GetAllTextFrames(pptxPresentation, true);

   //Loop through the Array of TextFrames
   for (int i = 0; i < textFramesPPTX.Length; i++)

   //Loop through paragraphs in current ITextFrame
   foreach (IParagraph para in textFramesPPTX[i].Paragraphs)

       //Loop through portions in the current IParagraph
       foreach (IPortion port in para.Portions)
       {
           //Display text in the current portion
           Console.WriteLine(port.Text);

           //Display font height of the text
           Console.WriteLine(port.PortionFormat.FontHeight);

           //Display font name of the text
           if (port.PortionFormat.LatinFont != null)
               Console.WriteLine(port.PortionFormat.LatinFont.FontName);
       }
