Extensible Notepad made by WPF

Remember there was a WinForm. Using reflection to do the extensible notebook, idle to Nothing, then with WPF also made an extensible Notepad, the interface can be dynamically extended functionality, simpler, for reference:

The directory structure is as follows:

MainWindow.xaml main function interface, Functionexpand provides expansion interface;

The main function code is as follows:

private void Makefun ()
{
String location = this. GetType (). Assembly.location;
String dllpath = System.IO.Path.GetDirectoryName (location) + "\\plugs";

string[] Strdllpath = System.IO.Directory.GetFiles (DllPath, "*.dll");

foreach (var item in Strdllpath)
{
Assembly-Assembly.loadfile (item);

type[] types =. Getexportedtypes ();
Type Plugtype = typeof (IPlug);

foreach (Var t in types)
{
Determine if the Iplug interface is implemented
if (Plugtype.isassignablefrom (t))
{
Creating plug-in objects based on plug-in types
IPlug iplugobj = activator.createinstance (t) as IPlug;

Create a plug-in button
MenuItem menu = new MenuItem ();
Menu. Header = T.name;
THIS.EXPANDTOOL.ITEMS.ADD (menu);
Menu. Click + = Menu_click;
Menu. Tag = Iplugobj;
}

}

}

}

void Menu_click (object sender, RoutedEventArgs e)
{
MenuItem MenuItem = sender as MenuItem;
IPlug IPlug = Menuitem.tag as IPlug;
Tb_text.text = Iplug. Processtext (Tb_text.text);
}

The effect is as follows:
