List of classes in an assembly

Question

I've a DLL assembly, in which there are various classes. Each class has around 50-100 members and 4-5 functions. How can I create a list of all the classes and their respective members using a VB.NET program?

I need to show to the user for performing an operation using a particular class.

Assuming that you've your assembly loaded to thisAsm (in this ex I'm using the executing assembly),

This will get you all non abstract classes:

Assembly thisAsm = Assembly.GetExecutingAssembly();
List<Type> types = thisAsm.GetTypes().Where(t => t.IsClass && !t.IsAbstract).ToList();

And this will get you all classes that implements a specific interface.

(Eg. If you need to get only the classes that implements IYourInterface, then)

Assembly thisAsm = Assembly.GetExecutingAssembly();
List<Type> types = thisAsm.GetTypes().Where
            (t => ((typeof(IYourInterface).IsAssignableFrom(t) 
                 && t.IsClass && !t.IsAbstract))).ToList();

Once you've this list of items, you can show the members of each type, by calling the GetProperties() and GetMethods() on each member of the types list.

It should still be pretty straightforward to convert the C# to VB. — Elan Hasson, Apr 22 '11 at 15:45

See the documentation for System.Reflection.Assembly.GetTypes() and System.Type.GetMembers()

You can get all type that inherits from Form in VB.net:

Dim thisAsm As Assembly = Assembly.GetExecutingAssembly()
Dim types As List(Of Type) = thisAsm.GetTypes().Where(Function(t) t.BaseType = GetType(Form)).ToList()

Here is vb.net version based on @amazedsaint answer:

Dim thisAsm As Assembly = Assembly.GetExecutingAssembly()
Dim types As List(Of Type) = thisAsm
    .GetTypes()
    .Where(Function(t) t.IsClass AndAlso Not t.IsAbstract).ToList()

Dim thisAsm As Assembly = Assembly.GetExecutingAssembly()
Dim types As List(Of Type) = thisAsm
    .GetTypes()
    .Where(Function(t) ((GetType(IYourInterface).IsAssignableFrom(t) AndAlso t.IsClass AndAlso Not t.IsAbstract))).ToList()

Many examples are on the web. Here's one (in C# though).
