Can not add bullets for word using OpenXml - openxml

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:
Hello
world!
How can i get my expected result?

Answer 1

I realize this is far too late but maybe it can help others with the same question. The marked answer (by amurra) doesn't actually achieve the desired result. It simply creates a document with the list as content, just more completely than you. What you have added to the main document part is fine.
In the XML format, list items are defined as paragraphs with an indentation level and a numbering ID. This ID references the numbering rules defined in the NumberingDefinitionsPart of the document.
In your case, because you've set the numbering ID to be 1, the following code would map that ID of 1 to reflect a bulleted list as desired. Note the NumberingFormat and LevelText objects inside the Level object. These are the key components for your formatting.
NumberingDefinitionsPart numberingPart =
mainDocumentPart.AddNewPart<NumberingDefinitionsPart>("myCustomNumbering");
Numbering numElement = new Numbering(
new AbstractNum(
new Level(
new NumberingFormat() { Val = NumberFormatValues.Bullet },
new LevelText() { Val = "·" }
) { LevelIndex = 0 }
) { AbstractNumberId = 0 },
new NumberingInstance(
new AbstractNumId(){ Val = 0 }
){ NumberID = 1 }
);
numElement.Save(numberingPart);
For more information, check out the documentation for all the related classes on the Wordprocessing Namespace on MSDN, or the Working With Numbering markup article.

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();
document1.AddNamespaceDeclaration("ve", "http://schemas.openxmlformats.org/markup-compatibility/2006");
document1.AddNamespaceDeclaration("o", "urn:schemas-microsoft-com:office:office");
