Question

My expected result is:

• Hello
• world!

but when i using below codes:

        MainDocumentPart mainDocumentPart =
          package.AddMainDocumentPart();

        DocumentFormat.OpenXml.Wordprocessing.Document elementW =
          new DocumentFormat.OpenXml.Wordprocessing.Document(
            new Body(
              new DocumentFormat.OpenXml.Wordprocessing.Paragraph(
                    new NumberingProperties(
                      new NumberingLevelReference() { Val = 0 },
                      new NumberingId() { Val = 1 })
                    ),
                new Run(
                  new RunProperties(),
                  new Text("Hello, ") { Space = new DocumentFormat.OpenXml.EnumValue<DocumentFormat.OpenXml.SpaceProcessingModeValues> { InnerText = "preserve" } })),
              new DocumentFormat.OpenXml.Wordprocessing.Paragraph(
                new ParagraphProperties(
                  new NumberingProperties(
                    new NumberingLevelReference() { Val = 0 },
                    new NumberingId() { Val = 1 })),
                new Run(
                  new RunProperties(),
                  new Text("world!")
                  {
                      Space = new DocumentFormat.OpenXml.EnumValue<DocumentFormat.OpenXml.SpaceProcessingModeValues> { InnerText = "preserve" }
                  })));

        elementW.Save(mainDocumentPart);

Result is:

1. Hello
2. world!

How can i get my expected result?

This should create you a blank document with your expected output:

        // Creates an Document instance and adds its children.
        public Document GenerateDocument()
        {
            Document document1 = new Document();
