ایجاد فایلword و نوشتن در آن از طریق c#

[sara.pazhrang]

کدی که بتواند یک فایل word جدید باز کند و متنی را در آن بنویسد .(متن را از textBox بگیرد یا از داخل بانک اطلاعاتی چاپ کند)
در MSDN Online کد زیر را برداشتم اما missingراو Application در خط دوم رانمی شناسد:
Microsoft.Office.Interop.Word.Application word_app = new Microsoft.Office.Interop.Word.Application();
this.Application.Documents.Add(ref missing, ref missing, ref missing, ref missing);

با سلام
بجاى missing از null استفاده کنید.

صبا صبوحى

[sara.pazhrang]

باز هم error می دهد.
برنامه را به صورت زیر تغییر دادم تا فایلwordی که در مسیرfilenameذخیره کرده ام را باز کند:

Microsoft.Office.Interop.Word.Application word_app = new Microsoft.Office.Interop.Word.Application();
object fileName = @"C:\myword.doc";
word_app.Documents.Open(ref fileName, ref null, ref null, ref null, ref null, ref null, ref null, ref null, ref null, ref null, ref null, ref null, ref null, ref null, ref null, ref null);

پیام خطا به صورت زیر است:
A ref or out argument must be an assignable variable

Argument '2': cannot convert from '<null>' to 'ref object'
