How find text in shape pptx (Spire.Presentation)

Question

Faced the problem of changing the text in the presentation. I use Spire.Presentation and there are a lot of different shapes on the page. My version finds only 1 text of 10. how to change Shapes[i] that i can get all the texts

using Spire.Presentation;
using System;
using System.Linq;
using System.Collections.Generic;
    static void Main(string[] args)
            {
                Presentation presentation = new Presentation();
                //Open presentation and convert slides
                presentation.LoadFromFile(@"C:\input.pptx");
                //if (presentation == null) { return };
                List<string> texts = new List<string>();
                for (int i = 0; i < presentation.Slides.Count; i++)
                {
                    //Get the shape from slide, get the text from shape and save to a new string variable.
                    IAutoShape shape = presentation.Slides[i].Shapes[i] as IAutoShape;IAutoShape shape = presentation.Slides[i].Shapes.GetEnumerator() as IAutoShape;
            if (shape != null)
            {
                foreach (var s in shape.ToString())
                {
                    var originalText = shape.TextFrame.TextRange;
                    originalText.FontHeight = 12;
                    originalText.IsItalic = TriState.True;
                    originalText.TextUnderlineType = TextUnderlineType.Single;
                    originalText.LatinFont = new TextFont("Arial");
                }
            }
            Console.WriteLine(shape);
            Console.ReadKey();
                    //save the slide to Image
                    var image = presentation.Slides[i].SaveAsImage();
                    String fileName = String.Format(@"C:\img-{0}.png", i);
                    image.Save(fileName, System.Drawing.Imaging.ImageFormat.Png);
                }
            }

Looks like you are looping through your slides but aren't looping through all the Shapes on your slide. This code will take

the first shape of the first slide
the second shape of the second slide
the third shape of the third slide
...

I think your solution is to also loop through all the Shapes in each page, like this:

    using Spire.Presentation;
    using System;
    using System.Linq;
    using System.Collections.Generic;
        static void Main(string[] args)
                {
                    Presentation presentation = new Presentation();
                    //Open presentation and convert slides
                    presentation.LoadFromFile(@"C:\input.pptx");
                    //if (presentation == null) { return };
                    List<string> texts = new List<string>();
                    for (int i = 0; i < presentation.Slides.Count; i++)
                    {
                      for(int j = 0; j < presentation.Slides[i].Shapes.Count;j++)
                      {
                        //Get the shape from slide, get the text from shape and save to a new string variable.
                        IAutoShape shape = presentation.Slides[i].Shapes[j] as IAutoShape;IAutoShape shape = presentation.Slides[i].Shapes.GetEnumerator() as IAutoShape;
                if (shape != null)
                {
                    foreach (var s in shape.ToString())
                    {
                        var originalText = shape.TextFrame.TextRange;
                        originalText.FontHeight = 12;
                        originalText.IsItalic = TriState.True;
                        originalText.TextUnderlineType = TextUnderlineType.Single;
                        originalText.LatinFont = new TextFont("Arial");
                    }
                }
                Console.WriteLine(shape);
                Console.ReadKey();
                        //save the slide to Image
                        var image = presentation.Slides[i].SaveAsImage();
                        String fileName = String.Format(@"C:\img-{0}.png", i);
                        image.Save(fileName, System.Drawing.Imaging.ImageFormat.Png);
                    }
                  }
                }
