Below function will show you how to open - close and copy from word doc.

using MsWord = Microsoft.Office.Interop.Word;
private static void MsWordCopy()
    {
        var wordApp = new MsWord.Application();
        MsWord.Document documentFrom = null, documentTo = null;

        try
        {
            var fileNameFrom = @"C:\MyDocFile.docx";               

            wordApp.Visible = true;

            documentFrom = wordApp.Documents.Open(fileNameFrom, Type.Missing, true);
            MsWord.Range oRange = documentFrom.Content;
            oRange.Copy();

            var fileNameTo = @"C:\MyDocFile-Copy.docx";
            documentTo = wordApp.Documents.Add();
            documentTo.Content.PasteSpecial(DataType: MsWord.WdPasteOptions.wdKeepSourceFormatting);
            documentTo.SaveAs(fileNameTo);              
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

        finally
        {
            if (documentFrom != null)
                documentFrom.Close(false);

            if (documentTo != null)
                documentTo.Close();

            if (wordApp != null)
                System.Runtime.InteropServices.Marshal.ReleaseComObject(wordApp);

            wordApp = null;
            documentFrom = null;
            documentTo = null;

            GC.Collect();
            GC.WaitForPendingFinalizers();
        }
    }
