Throwing Custom Exception Types from a Managed COM+ Server Application

摘要

Exception handling semantics in .NET are based on type, so you can create custom exceptions that have their own properties and methods. In .NET, exceptions are first-class citizens, and since they're the built-in error handling mechanism, all .NET-compliant languages must support exceptions. In addition, COM+ services are available to .NET code as Enterprise Services, so you can leverage exceptions in your Enterprise Services design. In this article the author describes custom exceptions, throwing exceptions across COM interop boundaries, and working with Enterprise Services.
