Introduction

FYI, here's the DTD for Apple Plist 1.0.

Now, to the code. This ...

using (PropertyListWriter writer = new PropertyListXmlWriter(Console.Out))
{
  PropertyList plist = new PropertyList();
  plist["allowOnion"].Bool = true;
  plist["volume"].Int = 42;
  plist["name"].String = "Jean-Baptiste Emanuel Zorg";
  plist.Save(writer);
}

... produces:

<!-- DTD stuff omitted -->
<plist version="1.0">
  <dict>
     <key>allowOnion</key>
     <true />
     
     <key>volume<key>
     <integer>42</integer>

     <key>name</key>
     <string>Jean-Baptiste Emanuel Zorg</string>
  </dict>
</plist>
