c# - Throwing ExternalException with custom HResult -

-

i wanted throw exception custom hresult or errorcode have tried externalexception

code

throw new externalexception("login required", 0x6acfc5);

however when catch exception , it's hresult, find not 0x6acfc5 strange negative number.

externalexception("login required", 0x6acfc5)

this constructor accept errorcode second parameter, , in system.int32

when give value 0x6acfc5 convert int value 7000005, that's see hresult

if call ex.hresult.tostring("x") 6acfc5

note: tostring("x") convert int value hexadecimal string
