  • 0

I’ve got the following bit of code that generates a list I’m trying to process. I need to create multiple files as I go through the list.

Currently I’m getting the following error on the calls to genStream outside of the IF, (in and out of the FOREACH loop), and I’m not sure why:

The name genStream' does not exist in the current context

I’m trying to figure out how I can close the one stream, and open another in the IF statement. I tried to put a .close() before creating the new stream, and it gave me an error for using it before initializing the stream.

Here is my bit of code:

    /// <summary>
    /// Creates a file for each Genre, and writes movie info to each for the cooresponding movies
    /// </summary>
    /// <param name="cPath">Path to create HTML files in</param>
    /// <param name="mList">List of Movies to generate Genre and Movie info from</param>
    public static void WriteGenreHTML(string cPath, List<Movie> mList)
    {
        int lineID = 0;
        string tmpGen = null;
        string strHeader, strMovie, strGenre, tmpGenre = null;

        // Gets a list of unique Genres from the MovieList
        var distinctGenres = from m in mList
                             from genre in m.Genres
                             group genre by genre into genres
                             select genres.First();

        // Gets a list of Movies with the associated Genres
        var moviesWithGenre = from g in distinctGenres
                              from m in mList
                              where m.Genres.Contains(g)
                              orderby g, m.Title
                              select new { Genre = g, Movie = m };

        // Traverses list of movies creating new HTML Genre files, and writing movie info to the HTML genre files
        foreach (var m in moviesWithGenre)
        {
            // Creates new HTML file if new Genre is detected
            if (m.Genre != tmpGen)
            {
                tmpGen = m.Genre;

                // initiates streamwriter for catalog output file
                FileStream fs = new FileStream(cPath + Path.DirectorySeparatorChar + m.Genre, FileMode.Create);
                StreamWriter genStream = new StreamWriter(fs);

                // Generates header info for new file, and new Genre
                strHeader = "<style type=\"text/css\">\r\n" + "<!--\r\n" + "tr#odd {\r\n" + "   background-color:#e2e2e2;\r\n" + "  vertical-align:top;\r\n" + "}\r\n" + "\r\n" + "tr#even {\r\n" + "   vertical-align:top;\r\n" + "}\r\n" + "div#title {\r\n" + "  font-size:16px;\r\n" + "    font-weight:bold;\r\n" + "}\r\n" + "\r\n" + "div#mpaa {\r\n" + "    font-size:10px;\r\n" + "}\r\n" + "\r\n" + "div#genre {\r\n" + " font-size:12px;\r\n" + "    font-style:italic;\r\n" + "}\r\n" + "\r\n" + "div#plot {\r\n" + "   height: 63px;\r\n" + "  font-size:12px;\r\n" + "    overflow:hidden;\r\n" + "}\r\n" + "\r\n" + "div#genre_heading {\r\n" + "    height: 50px;\r\n" + "  font-size: 24px;\r\n" + "   font-weight: bold;\r\n" + " text-align: center;\r\n" + "    text-decoration: underline;\r\n" + "}\r\n" + "-->\r\n" + "</style>\r\n" + "\r\n" + "<html>\r\n" + " <body>\r\n" + "     <table>\r\n";
                strHeader += "          <tr>\r\n" + "               <td colspan=2>\r\n" + "                 <div id=\"genre_heading\">" + m.Genre + "</div>\r\n" + "                </td>\r\n" + "          </tr>\r\n" + "\r\n";

                // Writes header HTML to stream
                genStream.WriteLine(strHeader);

                Console.WriteLine();
                Console.WriteLine("Now Processing " + m.Genre);
            }

            // Generates the HTML for the Movie
            strMovie = lineID == 0 ? "          <tr id=\"odd\" style=\"page-break-inside:avoid\">\r\n" : "          <tr id=\"even\" style=\"page-break-inside:avoid\">\r\n";
            strMovie += "               <td>\r\n" + "                   <img src=\".\\images\\" + m.Movie.ImageFile + "\" width=\"75\" height=\"110\">\r\n" + "             </td>\r\n" + "              <td>\r\n" + "                   <div id=\"title\">" + m.Movie.Title + "</div>\r\n" + "                  <div id=\"mpaa\">" + m.Movie.Certification + " " + m.Movie.MPAA + "</div>\r\n" + "                  <div id=\"genre\">" + strGenre + "</div>\r\n" + "                   <div id=\"plot\">" + m.Movie.Plot + "</div>\r\n" + "                </td>\r\n" + "          </tr>\r\n";

            // Writes the HTML to the stream
            genStream.WriteLine(strMovie);
            lineID = lineID == 0 ? 1 : 0;
        }

        string closingHTML = "      </table>\r\n" + "   </body>\r\n" + "</html>";
        genStream.WriteLine(closingHTML);
        genStream.Close();
    }

Side note. I’d GREATLY appreciate it if someone could point me towards something I can use to convert the HTML files into PDFs. I tried EO, and it has a nasty “watermark”, and chokes on files over a couple MB (mine are 5-10mb+). I have WkHTMLToSharp, but I am not sure how to use it, and can’t find any documentation on how to intitialize/use it.

Thanks as always!

    Declare the genStream outside of foreach loop, and then initialize it as needed within the if statement:

    StreamWriter genStream;

foreach (var m in moviesWithGenre)
{
    // Creates new HTML file if new Genre is detected
    if (m.Genre != tmpGen)
    {
        tmpGen = m.Genre;

        // initiates streamwriter for catalog output file
        FileStream fs = new FileStream(cPath + Path.DirectorySeparatorChar + m.Genre, FileMode.Create);
        // Set genStream to the FileStream
        genStream = new StreamWriter(fs);
