c# - Aspose 不能写多个段落

问题描述

当我尝试在现有 Shape 中编写多个段落时遇到问题。只写了第一段。我调试了代码，发现 Shape 对象是我想要的所有段落。问题是当我写入文件时，我只找到了第一个。我与您分享项目代码。

class Program
    {
        public static void Run()
        {

            string dataDir = ConfigurationManager.AppSettings["directoryToSave"];
            string srcDir = ConfigurationManager.AppSettings["Source"];
            string appData = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
            string file = Path.Combine(appData, srcDir);
            using (Presentation presentation = new Presentation(srcDir))
            {
                IMasterLayoutSlideCollection layoutSlides = presentation.Masters[0].LayoutSlides;
                ILayoutSlide layoutSlide = null;

                foreach (ILayoutSlide titleAndObjectLayoutSlide in layoutSlides)
                {
                    if (titleAndObjectLayoutSlide.Name == "TITRE_CONTENU")
                    {
                        layoutSlide = titleAndObjectLayoutSlide;
                        break;
                    }
                }            

                var contenu = File.ReadAllText(@"E:\DemosProject\PF_GEN\PF_GEN\Source\contenu.txt", Encoding.UTF8);
                IAutoShape contenuShape = (IAutoShape)layoutSlide.Shapes.SingleOrDefault(r => r.Name.Equals("contenu"));

                ITextFrame txt = ((IAutoShape)contenuShape).TextFrame;
                txt.Paragraphs.Clear();
                string[] lines = contenu.Split(new[] { Environment.NewLine }, StringSplitOptions.None).Where(str => !String.IsNullOrEmpty(str)).ToArray();
                for (int i = 0; i < lines.Length; i++)
                {
                    var portion = new Portion();
                    portion.Text = lines[i];
                    var paragraphe = new Paragraph();
                    paragraphe.Portions.Add(portion);
                    txt.Paragraphs.Add(paragraphe);
                }
                presentation.Slides.InsertEmptySlide(0, layoutSlide);
                presentation.Save(dataDir + "AddLayoutSlides_out.pptx", SaveFormat.Pptx);
            }
        }

        static void Main(string[] args)
        {
            try
            {
                var path = ConfigurationManager.AppSettings["sourceAsposeLicensePath"];
                License license = new License();
                license.SetLicense(path);
                Run();
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error" + ex.Message);
            }
            finally
            {
                Console.WriteLine("Terminated");
                Console.ReadKey();
            }
        }

    }

您可以在附件文件中找到 ppt 文件（源文件）。（https://gofile.io/?c=JpBDS8 1）我的代码中是否缺少任何东西？谢谢

解决方案

@Adouani Riadh，

我已经观察到您的要求，并建议您尝试使用以下示例代码。在您的示例代码中，您将不同的段落添加到 LayoutSlide 内的形状中，然后使用该 LayoutSlide 添加幻灯片以包含所需的形状。这种方法是不正确的。您实际上需要首先添加基于 LayoutSlide 的幻灯片，然后根据您的要求将文本添加到该形状。以下代码将对您有所帮助。

    public static void RunParaText()
    {

        string path = @"C:\Aspose Data\";

        string dataDir = path;
        string srcDir = path + "Master.pptx";
        //string appData = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
        //string file = Path.Combine(appData, srcDir);

        using (Presentation presentation = new Presentation(srcDir))
        {
            IMasterLayoutSlideCollection layoutSlides = presentation.Masters[0].LayoutSlides;
            ILayoutSlide layoutSlide = null;

            foreach (ILayoutSlide titleAndObjectLayoutSlide in layoutSlides)
            {
                if (titleAndObjectLayoutSlide.Name == "TITRE_CONTENU")
                {
                    layoutSlide = titleAndObjectLayoutSlide;
                    break;
                }
            }

            var contenu = File.ReadAllText(dataDir+"contenu.txt", Encoding.UTF8);
            var slide=presentation.Slides.InsertEmptySlide(0, layoutSlide);
            IAutoShape contenuShape = (IAutoShape)slide.Shapes.SingleOrDefault(r => r.Name.Equals("contenu"));

            //IAutoShape contenuShape = (IAutoShape)layoutSlide.Shapes.SingleOrDefault(r => r.Name.Equals("contenu"));

            ITextFrame txt = ((IAutoShape)contenuShape).TextFrame;
            txt.Paragraphs.Clear();
            string[] lines = contenu.Split(new[] { Environment.NewLine }, StringSplitOptions.None).Where(str => !String.IsNullOrEmpty(str)).ToArray();

            for (int i = 0; i < lines.Length; i++)
            {
                var portion = new Portion();
                portion.Text = lines[i];
                var paragraphe = new Paragraph();
                paragraphe.Portions.Add(portion);
                txt.Paragraphs.Add(paragraphe);
            }

            //Change font size w.r.t shape size
            contenuShape.TextFrame.TextFrameFormat.AutofitType = TextAutofitType.Normal;

            presentation.Save(dataDir + "AddLayoutSlides_out.pptx", SaveFormat.Pptx);
        }
    }
