Word PDF .net C#
[解决办法]
没搞过pdf
不过，瞧瞧的告诉你，其实用C#4.0写com代码是很简洁的
C#3

        static void Main()
        {
            object missing = Type.Missing;
            var app = new Application { Visible = false };
            app.Documents.Add(ref missing, ref missing, ref missing, ref missing);
            Document doc = app.ActiveDocument;
            Paragraph para = doc.Paragraphs.Add(ref missing);
            para.Range.Text = "Thank goodness for C# 4";
            object filename = "demo.doc";
            object format = WdSaveFormat.wdFormatDocument97;
            doc.SaveAs(ref filename, ref format,
                       ref missing, ref missing, ref missing,
                       ref missing, ref missing, ref missing,
                       ref missing, ref missing, ref missing,
                       ref missing, ref missing, ref missing, 
 
                       ref missing, ref missing);
            doc.Close(ref missing, ref missing, ref missing);
            app.Application.Quit(ref missing, ref missing, ref missing);
        }

C#4代码

        static void Main()
        {
            var app = new Application { Visible = false };
            app.Documents.Add();
            Document doc = app.ActiveDocument;
            Paragraph para = doc.Paragraphs.Add();
            para.Range.Text = "Thank goodness for C# 4";
            doc.SaveAs(FileName: "test.doc",
                       FileFormat: WdSaveFormat.wdFormatDocument97);
            doc.Close();
            app.Application.Quit();
        }
