我现在要从ppt文件的幻灯片中获取所有形状，我想从这些形状中获取文本，我该怎么做

这是我在ppt文件中获取所有幻灯片形状的方法

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);

                }
            }

        }
    }

现在我能从中得到文本吗

如果您没有许可证，aspose将为您提供截断的文本。因此，如果您使用Microsoft.Office.Interop.PowerPoint，对您会更好

使用如下

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 + " ";
                }
            }
        }

}
