I haven't had to do it yet, so I'm just kind of going off of what looks available within my installed Revit package...
I'm thinking you need to have the file exported out of Microstation as an .ifc file. Then you can open the .ifc file in Revit (Revit Start button> Open> Ifc file) and save as a Revit file.

Thank you for the response.
This is what MicroStation can export, But could not find *.IFC format.
Do you think I need to install some special software?
IFC export isn't available from MicroStation. However, it is available from one of the Bentley BIM applications such as Bentley Architecture, Structural Modeler, Bentley Building Mechanical Systems, or Bentley Building Electrical Systems. If you just need to view the model in Revit, you can do a Save As in MicroStation to AutoCAD DWG format, and then import/link the DWG into Revit. You won't have any intelligence, but then again there shouldn't be any if the model was created with MicroStation alone and not one of the Bentley BIM products.
