A Simple Game Editor in C# - Game Coding Complete - page 782

The XmlDocument is responsible for creating new elements by calling CreateEle-
ment() , and each element can have multiple children, which are attached with the
AppendChild() method. Notice the call to ImportNode() inside the loop? This
call is required to create a copy of an XmlElement created in a different XmlDocu-
ment object.
Once the entire XmlDocument object is ready, it is saved by creating an XmlText-
Writer . The formatting is set so that it makes for easier human reading and editing.
The last menu action is for building the Zip file that contains the entire Assets direc-
tory. For that, a helper class, ZipFileUtility , is needed.
private void buildProjectToolStripMenuItem_Click(object sender, EventArgs e)
{
ZipFileUtility.Create(m_AssetsDirectory,
m_ProjectDirectory + “\\Assets.zip”);
}
System.IO.Packaging has a convenient class called ZipPackaging , which can
create or read Zip files, and will form the basis of the ZipFileUtility class.
class ZipFileUtility
{
public static void Create(string rootDirectoryName, string zipFileName)
{
DirectoryInfo rootDirectory = new DirectoryInfo(rootDirectoryName);
int rootDirLen = rootDirectory.FullName.Length;
using (Package package = ZipPackage.Open(zipFileName, FileMode.Create))
{
var stack = new Stack<string>();
stack.Push(rootDirectory.FullName);
while (stack.Count > 0)
{
var currentNode = stack.Pop();
var directoryInfo = new DirectoryInfo(currentNode);
foreach (var directory in directoryInfo.GetDirectories())
{
FileAttributes attributes =
File.GetAttributes(directory.FullName);
if ((attributes & FileAttributes.Hidden) == 0 &&
directory.Name != “Editor”)
{
stack.Push(directory.FullName);
}
