Kieren5:
Using reflection emit and the technique described in this post (with sample code):

http://www.xtremedotnettalk.com/showthread.php?t=96952

I was able to invoke an instance method on a class.

The only change necessary is the constructor of the DynamicMethod. The sample code uses this constructor, which is not allowed in Silverlight (for security):
[SecurityCriticalAttribute]
public DynamicMethod(
string name,
Type returnType,
Type[] parameterTypes,
Type owner
)
Change it to this one:
public DynamicMethod(
	string name,
	Type returnType,
	Type[] parameterTypes
)

That information and the reasons for it are ALL in the link I gave you, but I'm glad you're satisfied.

DynamicMethod Invoke Instance Method

Kieren5 — Fri, 19 Sep 2008 23:02:18 GMT

Is it possible to invoke an instance method from a DynamicMethod in Silverlight?

This sample shows how to access an instance field on a class:

Is it possible to call a method on a class using a similar technique, any guidance or samples.

There is a sample for .Net 3.5, but it doesn't work in Silverlight because you can only use the first DynamicMethod constructor (the rest have a secuirty attribute :S ):
