identify tool in c#

I am using ARCObject SDK 10.1. In one of my application i want that when user clicks map layer than i can read the data assoicated to the attribute table of the layer at the clicked point. I know identify tool does this job in arc map. I want the similar function without displaying the identify tool dialog box. I would appreciate ant hint or direction to start with. how to execute a query from c sharp to reterive the data from the assoicated attribute table of the layer.
