When does the runtime throw a comexception class?
When the runtime encounters an unfamiliar HRESULT (an HRESULT that lacks a specific, corresponding exception), it throws an instance of the COMException class. This all-purpose exception exposes the same members as any exception, and inherits a public ErrorCode property that contains the HRESULT returned by the callee.
How does Common Language Runtime transform HRESULTs to exceptions?
The common language runtime transforms well-known HRESULTs to .NET Framework exceptions, enabling COM objects to return meaningful error information to managed clients. The HRESULT to exception mapping also works in the other direction by returning specific HRESULTs to unmanaged clients. For mapping details, see How to: Map HRESULTs and Exceptions.
