When implementing IDisposable, I undertand that every method that shouldn't be called after the object's been disposed should throw the ObjectDisposedException
. But what is the standard for the name object that should be passed to the exception's constructor?
回答1:
I believe the recommended practice is to throw the following:
throw new ObjectDisposedException(GetType().FullName);
Or including the check, these two lines of code at the top of each method that needs it (obviously not the Dispose
method itself):
if (this.disposed)
throw new ObjectDisposedException(GetType().FullName);
Might even be helpful to refactor this into a tiny method for usability.
回答2:
Even the .NET Framework itself isn't very consistent here.
David M. Kean (former developer on the FxCop team at Microsoft) added a comment to the MSDN documentation for the ObjectDisposedException:
The typical usage of this type is something like the following:
[C#] private void CheckDisposed() { throw new ObjectDisposedException(GetType().FullName); }
回答3:
I don't believe there's a standard for that, I would return the type of the object along with the string content of a unique identifying field (a 'Primary Key' of sorts).
