Chris King reflecting on his own webblog. Hello World!

What's the weblog of Dario Russi?

Welcome! Looking forward to your CLR/Reflection posts.

Great! Waiting for cool info :) Btw, could you point to someone from System.ComponentModel?

In CLR 1.2 (Visual Studio 2005), what kind of speed improvements can we expect over CLR 1.1?

Do U have any data similar to http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/highperfmanagedapps.asp for reflection?

I've noticed MethodBase::GetMethodBody in Whidbey, which means it is /almost/ possible to slurp in an assembly, manipulate it, and write out the transformed one with Reflection Emit. But is it possible to access custom attributes in their un-constructed form (i.e. as a ConstructorInfo, argument list and keyword arguments-- like what you need to synthesize the same attribute with a ConstructorBuilder?)

I'm having a time getting ref parameters to work from .net to a COM object. I can call the method fine without passing a ParameterModifier, but I get a TargetInvocationException with a CommException of 'Invalid callee' when I attempt to pass the ParameterModifier and set one of the params to ref. Here the code snippet...

tCSCS = System.Type.GetTypeFromProgID(CSCS_CLASS_ID);

oCSCS = tCSCS.InvokeMember(null, BindingFlags.CreateInstance, null, null, null);

long matchedRec = 0;
object[] args = {searchValues, matchedRec};

ParameterModifier[] pm = new ParameterModifier[1] {new ParameterModifier(2)};
pm[0][0] = false;
pm[0][1] = true;

object rc = tCSCS.InvokeMember("GetCaseCount", BindingFlags.InvokeMethod, null, oCSCS, args, pm, null, null);

I'm stuck!
