Hello,
When I use that specific template file I get an message that "PowerPoint can attempt to repair the presentation."

I am using the Spire.Presentation (7.1.0) library. But it is same for FreeSpire.Presentation (6.8.5). What is the problem and how can I fix it.

Thank you.

Template File:
template02.zip


Source Code:

Code: Select all
using Spire.Presentation;
using System.Linq;
using Spire.Presentation.Charts;
using System;

namespace PptxTesterPaidVersion
{
    class Program
    {
        static void Main(string[] args)
        {
            TestFileCorrupt();
        }

        private static void TestFileCorrupt()
        {
            //Load template presentation
            Presentation templatePresentation = new Presentation();
            templatePresentation.LoadFromFile("template02.pptx");

            //Create New Presentation
            Spire.Presentation.Presentation presentation = new Spire.Presentation.Presentation();
            presentation.Slides.RemoveAt(0);

            //Get slide from template presentation. index:1
            ISlide cloneSlide = templatePresentation.Slides.ToArray().ElementAtOrDefault(0);

            //---
            //Get Chart                       
            //IChart chart = templateSlide.Shapes.ToArray().FirstOrDefault(x => x.Name == "Content Placeholder 15") as IChart;
            IChart chart = cloneSlide.Shapes.ToArray().FirstOrDefault(x => x.Name == "Content Placeholder 15") as IChart;

            int seriesCount = 1;
            int categoryCount = 9;

            chart.ChartData.Clear(0, 0, categoryCount + 1, seriesCount + 1);

            chart.ChartData[9, 1].NumberValue = 0.33;


            var startIndexAddSeries = chart.Series.Count + 1;
            for (int i = startIndexAddSeries; i <= 4; i++)
            {
                chart.Series.Append(chart.ChartData[0, i]);
            }
            if (chart.Series.Count > seriesCount)
            {
                for (int i = chart.Series.Count - 1; i >= seriesCount; i--)
                {
                    chart.Series.RemoveAt(i);
                }
            }
            chart.Categories.CategoryLabels = chart.ChartData["A2", "A" + (categoryCount + 1)];
            for (int i = 0; i < seriesCount; i++)
            {
                string letter = GetColumnName(i + 1);
                chart.Series[i].Values = chart.ChartData[letter + "2", letter + (categoryCount + 1)];
            }

            presentation.Slides.Append(cloneSlide);

            //Save and launch to view the PPTX document.
            presentation.SaveToFile("TestFileCorrupt_01.pptx", Spire.Presentation.FileFormat.Pptx2010);
        }

        public static string GetColumnName(int index)

            var value = "";

            if (index >= letters.Length)
                value += letters[index / letters.Length - 1];

            value += letters[index % letters.Length];

            return value;
        }
