I’m using PDF Kit v.3.5.0.0, and whenever I call the first method in it, it generates 315 ArgumentOutOfRangeExceptions, which it throws, catches, and ignores internally. This slows down the first usage, and it makes for a terrible experience in the debugger if you have it set to break whenever an exception is thrown.
I’ve attached a simple C# project that demonstrates the problem. It just calls SetPrivilege on an input pdf file. Internally, the Aspose code does some one-time initialization, and it throws an ArgumentOutOfRangeException when it encounters a “;” somewhere. Then it catches the exception and ignores it. The stack trace is shown below. Then this pattern is repeated 315 times!
The performance and debuggability of this would be much improved if the caller would check for the “exceptional” condition (i.e., the “;” value) before calling the code that throws. You could even use a new internal bool method that checks the state and returns false without throwing, since the calling code will just eat the exception anyway. The current implementation is very “unfriendly” to the debugger.
