Answer 1

Surprisingly enough, this code compile and run, but the outcome is not what you probably wanted.

A couple of things is wrong in this code:

1.you cant add strings like that to create a path, a path should be created with the '/' symbol between directories. this is a legal path:

string path = @"C:\Users\username\Desktop\Games";

this is not :

string path = @"C:UsersusernameDesktopGames";

you can fix it by using the Path.Combine function as follow:

docfile_path = Path.Combine(File_path , "test" , date);

be sure to this for all path strings (including File_path that is value is not shown in the code above).

2.you should use

Document doc = app.Documents.Add();

to create a new Word document and not

Document doc = new Document();

3.you should use a different format for string date, DateTime.ToShortDateString() is dividing the date with the '/' symbol which will create new folders. try using:

string date = DateTime.Today.ToString("dd.MM.yyyy");

4.I don't see any reason for the line

doc = app.Documents.Open(filename);

You are trying to open the the file that you intent to create?

here is the code i used:

        string File_path = @"C:\Users\yakir\Desktop"; 
        string docfile_path;
        string filename;

        string time = DateTime.Now.ToString("HH.mm.ss");
        string date = DateTime.Today.ToString("dd.MM.yyyy");

        docfile_path = Path.Combine(File_path , "test" , date);
        Directory.CreateDirectory(docfile_path);

        filename = Path.Combine(docfile_path, "worddoc" + "-" + ".docx");


        Application app = new Application();
        Document doc = app.Documents.Add();

        Paragraph oPara1;
        oPara1 = doc.Content.Paragraphs.Add();
        oPara1.Range.Text = "Test Result";
        oPara1.Range.Font.Bold = 1;
        oPara1.Format.SpaceAfter = 24;
        oPara1.Range.InsertParagraphAfter();
        oPara1.Range.InsertParagraphAfter();
        Paragraph oPara2;
        oPara2 = doc.Content.Paragraphs.Add();
        oPara2.Range.Text = "Test Name";
        oPara2.Range.Font.Bold = 1;
        oPara2.Format.SpaceAfter = 24;
        oPara2.Range.InsertParagraphAfter();

        doc.SaveAs2(filename);
        doc.Close();
        doc = null;

        app.Quit();
        app = null;
    }
