I'm a newbie with ArcGIS development, so sorry if the answer is overly obvious.

I'm building a ArcMap tool in C# to do some geoprocessing.  I cannot figure out how to open an "input geodataset" dialog that returns the path to the geodataset...the kind you use when entering parameters for geoprocessing tools like "Clip", "Union", etc (see screen capture).  I know how to build a OpenFileDialog in C# and I can filter it for shapefiles, but that won't work if I want to select raster data, or coverages, or features from a geodatabase.  The dialog must be an object, but I can't find info on it. Tips?
