how to execute any method in any dll over entry Dll using appdomain?

Question

this is a strange question. i can load 15 Dll's from plugins directory. But i have basePluginToRunothers.DLL which task execute other 14 dlls. My Starter dll is basePluginToRunothers.DLL. How to run other dlls by using basePluginToRunothers.DLL in AppDomain.CurrentDomain?

enter image description here

How to use abc.dll,xyz.dll, klm.dll by using basePluginToRunothers.DLL which has RUN method? NOTE: ican load all dlls. other dlls will be execute over basePluginToRunothers'run method.

I think, you are able to load basePluginToRunothers.dll using reflection from main program. — Romil Kumar Jain, May 08 '12 at 13:08
yes i can . other dlls will be execute over basePluginToRunothers'run method. — loki, May 08 '12 at 13:16
Please let me know that are you able to execute all other 14 dll's or not. What exact issue you are facing? — Romil Kumar Jain, May 08 '12 at 13:19
i can execute other dllbut i want to execute 14dlls in basePluginToRunothers. basePluginToRunothers.Execute(select.FROM(AppdomainOTherDLLS)) — loki, May 08 '12 at 13:23
As per me, you have Execute/Run method in basePluginToRunothers dll. In this function, you are doing the reflection to load the all 14 dll's and executing the RUN method of all 14 dll's. Please correct me if your approach is different. — Romil Kumar Jain, May 08 '12 at 13:26
First: Load All DLLS in Appdomain.CurrentDomain SECOND: basePluginToRunothers Execute method.Start other dlls execute method — loki, May 08 '12 at 13:30
