Abstract: The difference between COM object and object module of .NET framework was elaborated. And the interoperation realization method between COM and .NET while COM as the server and .NET as the client, and con the contrary while .NET as the server and COM as the client was respectively narrated. Calling COM component in unmanaged code (.NET code) and .NET component in managed code was realized by taking advantage of runtime callable wrapper RCW and COM callable wrapper CCW. Thus, in the situation of the .NET technical maturing, programming of using the COM technology will much less than before. But the COM technology would not be completely replaced by .NET in the near future. So a great deal of existent products which are developed using COM component technology are protected and used through realizing the interoperation between the COM and the .NET technology, which also makes the COM programmers use easily the software based on the .NET technology.
