reflection

I am trying to examine the contents of an assembly and find all classes in it that are directly or indirectly derived from Windows.Forms.UserControl.

I am doing this:

Assembly dll = Assembly.LoadFrom(filename);
var types = dll.GetTypes().Where(x => x.BaseType == typeof(UserControl));

But it is giving an empty list because none of the classes directly extend UserControl. I don't know enough about reflection to do it quickly, and I'd rather not write a recursive function if I don't have to.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

Hi, I'm using a class which applies a visual reflection-effect to defined movieclips. I use a reflection-class from here: link to source.

System.Reflection - Global methods aren't available for reflection

as seen on Stack Overflow - Search for 'Stack Overflow'
I have an issue with a semantic gap between the CLR and System.Reflection. System.Reflection does not (AFAIK) support reflecting on global methods in an assembly. At the assembly level, I must start with the root types. My compiler can produce assemblies with global methods, and my standard bootstrap… >>> More
