Answer 1

I agree there so many messages, but I had this below file with my, while developing plugin and I look for the type of Input parameter first

I got this file from http://patrickverbeeten.com/Blog/2008/01/25/CRM-40-Plug-in-message-input-parameters

But I have tried to update this file somewhat for CRM 2011:

If I understand your question correct you can just do the following:

if (context.InputParameters.Contains("Target")) {
   // Do something with Target
}
else if (context.InputParameters.Contains(“Relationship”)) {
   // Do something with Relationship
}

If you want to confirm that Target is of Entity (I think it always is in the plugin) then I would think you could just do the following:

if (context.InputParameters["Target"].GetType() == new Entity().GetType()) {

}
