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 respec

Answer 1

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

Answer 2

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.

Answer 3

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

Answer 4

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()

Answer 5

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()
