Question

During my game, you can save a map and store the tiles in the map into a xml file.
So far no problem. The problem starts when I try to save it it gives me a UnauthorizedAccessException error somehow.

The folder is located in the installation dir of my game:

instal_dir/data/maps/

I checked to make sure, but the folder is created succesfully with the correct permissions (write, read and execute).

Am I doing something wrong?

Here is my code:

private void CreateXMLOfMap()
{
    List<Tile> tiles = mapContainer.GetTileList();
    XmlDocument doc = new XmlDocument();
    XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
    doc.AppendChild(docNode);

    XmlNode rootNode = doc.CreateElement("Map");
    doc.AppendChild(rootNode);

    XmlNode mapName = doc.CreateElement("Name");
    mapName.AppendChild(doc.CreateTextNode("custom_map"));
    rootNode.AppendChild(mapName);

    XmlNode tilesNode = doc.CreateElement("Tiles");
    rootNode.AppendChild(tilesNode);

    for (int i = 0; i < tiles.Count; i++ )
    {
        XmlNode tileNode = doc.CreateElement("Tile");
        tilesNode.AppendChild(tileNode);

        XmlNode positionNode = doc.CreateElement("Position");
        tileNode.AppendChild(positionNode);
        XmlNode xNode = doc.CreateElement("X");
        xNode.AppendChild(doc.CreateTextNode(tiles[i].GetTilePosition().X.ToString()));
        positionNode.AppendChild(xNode);
        XmlNode yNode = doc.CreateElement("Y");
        yNode.AppendChild(doc.CreateTextNode(tiles[i].GetTilePosition().Y.ToString()));
        positionNode.AppendChild(yNode);

        XmlNode textureNode = doc.CreateElement("Texture");
        textureNode.AppendChild(doc.CreateTextNode(tiles[i].GetTileInfo().Name.ToString()));
        tileNode.AppendChild(textureNode);

        XmlNode YFrameNode = doc.CreateElement("YFrame");
        YFrameNode.AppendChild(doc.CreateTextNode(tiles[i].GetCurrentFrame().Y.ToString()));
        tileNode.AppendChild(YFrameNode);
    }

    doc.Save(Constants.MAPS_DIRECTORY);
}

Okay, so I found the problem that caused this exception to show up. It appeard that I only included the directory, but not the file name. So it tried to store the content into the directory, instead of into a xml file.

All I had to change was to string that goes into

doc.Save(PATH_TO_DIR_WITH_FILE_NAME);

But I’ll keep in my, if I continue like this, I might end up needing administrator righs, so I’ll need to change it sooner or later.

Thanks all for your advice and help!
