Because you are going to throw the exception and there won't be anyone then to dispose of it. Exception handlers are often generic based on the base exception class and won't be ready to handle a disposable resource.

1. IDisposable interface provides a mechanism for releasing unmanaged resources, so it should be used only if you use them like: file streams, database connections, sockets, memory allocation, etc. See details in MSDN[^]

2.In the case of custom exception you should fallow the rules described here:
