hi there,

Can someone help me out with some example code (VB.NET) here that i need:

i would like to programatically check my ASP.NET web application and return
a list of all the ASPX and ASCX pages in the project, then return them in an
string array, eg. name : type ("default.aspx : ASPX")

i figured if i use the io.directory, it might even return items which could
be excluded from the project, which i dont want, thats why i think it might
be best to use the assembly??

thanks,

Paul.
 
You can come pretty close by using reflection.
The following snippet creates an ArrayList with the class
name and type of all pages and user controls within the
assembly:
Type[]
allTypes=Assembly.GetExecutingAssembly().GetTypes();
ArrayList
pagesAndUserControls=new ArrayList();
foreach (Type type in allTypes) {
if (type.IsSubclassOf
(typeof(System.Web.UI.Page))||type.IsSubclassOf(typeof
(System.Web.UI.UserControl))) {

pagesAndUserControls.Add(String.Format("{0} :
{1}",type.FullName,type.BaseType));
}
}

You will need to add the following using statement to the
class "using System.Reflection;"

Usually you give the code behind class the same name as
the aspx or ascx page. Eg. WebForm1.aspx has a class
named WebForm1. If you follow this patter you can
append ".aspx" or ".ascx" to the class names to get the
filename of the page or control.

Hello Anders,

One step is missing from your otherwise great instructions:

You're assuming that there is only one assembly containing the AS?X files
and that it is the currently executing one. It is very probable that a user
may have multiple assemblies in the bin directory (this is a practice I do
frequently).

To get around that, you'll need to add a loop to iterate the assemblies:

foreach (Assembly asm in AppDomain.CurrentDomain.GetAssemblies())
{
// your code goes here
}

After that, you'll want to modify your allTypes assignment this way:

Type[] allTypes = asm.GetTypes();
 
great!! thanks for the excellent example.. i had a fair idea what i was
after, but just didnt know exactly where to start code-wise.

just one small issue, i've converted the code into VB.NET, but one line is
giving me a problem:

If t.IsSubclassOf(typeOf(System.Web.UI.Page)) Or
t.IsSubclassOf(typeof(System.Web.UI.UserControl)) Then


it doesnt like this line of code how i have written it,any help?

thanks,
Paul

I'm think the VB.NET equivalent to typeof is GetType but I'm not sure.
BTW: I've got an updated example on how to do this posted on my blog.
