You can use Open XML which works fine
(can be done with Office Interop too, but it needs Office to be installed)

Basic sample : Create a word processing document by providing a file name

What is reason of error

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.
Source=WindowsFormsApp1

due to last line (with body line)?

static void Main() { WriteToNewWordDoc("y:/d2.docx", "Oct-6 One more line"); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } public static void WriteToNewWordDoc(string filepath, string txt) { // Open a WordprocessingDocument for editing using the filepath. //using (WordprocessingDocument wordprocessingDocument = // WordprocessingDocument.Open(filepath, true)) //{ using (WordprocessingDocument wordDocument = WordprocessingDocument.Create(filepath, WordprocessingDocumentType.Document)) { // Assign a reference to the existing document body. Body body = wordDocument.MainDocumentPart.Document.Body;

You create a document, so there is no Body yet
See the code for the creation of a new document : Sample Code

you just have to copy-paste MSDN code, and the .docx is created

Install the following NuGet package DocumentFormat.OpenXml.

Try creating a new document

using (var document = WordprocessingDocument.Create(fileName, WordprocessingDocumentType.Document)) { MainDocumentPart mainPart = document.AddMainDocumentPart(); mainPart.Document = new Document(); mainPart.Document.AppendChild(new Body()); mainPart.Document.Save(); }

The above is taken from Office Word Basic operations: Open XML SDK 2.5 Office Word documents with source code in the following repository project.

EDIT: Code sample to create a new document and write a single paragraph.

This is copy-paste of MSDN code already posted... useless

Not a copy and paste.
