open save as docx then close word

Question

So what I want to do is create a program that selects a map with .doc documents open that up save it as a docx then close word. I got it all but when I try to close Word it gives me an error.

Main code:

    public void ConvertAll(string docFilePathOriginal, string docFilePath, string outputDocxFilePath)
    {
        MessageBox.Show(docFilePathOriginal);

        DocFiles = new List<string>();
        //calls the method that fills the list with the documents witht the filter.
        FindWordFilesWithDoc(docFilePathOriginal, ".doc");
        //make a new word each time for max performance
        Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();

        foreach (string filename in DocFiles)
        {
            //exclude the .docx files, because the filter also accepts .docx files.
            if (filename.ToLower().EndsWith(".doc"))
            {
                try
                {
                var srcFile = new FileInfo(filename);

                var document = word.Documents.Open(srcFile.FullName);
                string docxFilename = srcFile.FullName.Replace(".doc", ".docx");

                document.SaveAs2(FileName: docxFilename, FileFormat: WdSaveFormat.wdFormatXMLDocument);
                }
                finally
                {
                    word.ActiveDocument.Close();
                }
            } 
        }
    }

Code that gets the .doc files:

void FindWordFilesWithDoc(string SelectedDirection, string filter)
    {
        //get all files with the filter and add them to the list.
        foreach (string d in Directory.GetDirectories(SelectedDirection))
        {
           foreach (string f in Directory.GetFiles(SelectedDirection))
           {
               DocFiles.Add(f);
           }
            //FindWordFilesWithDoc(d, filter);
        }
    }

The error it gives me:

Ambiguity between method 'Microsoft.Office.Interop.Word._Document.Close(ref object, ref object, ref object)' and non-method 'Microsoft.Office.Interop.Word.DocumentEvents2_Event.Close'. Using method group.

Answer 1

The problem is that there is a method Close(), and an event Close.

See this thread . As the poster there states, you probably want to use the method Close() instead of the event. In this case try to cast word.ActiveDocument to _Document , and call Close() on that.

Edit:
You can also set the type to _Application , instead of Application :

 Microsoft.Office.Interop.Word._Application word = new Microsoft.Office.Interop.Word.Application();

(note that I'm unable to test this at the moment, I don't have office installed on my current machine)
