Check the PInvoke signatures calling convention and parameters unmanaged target signature matches

solution:

[DllImport ( "Dll.dll")] to [DllImport ( "dll.dll", CallingConvention = CallingConvention.Cdecl)]
CallingConvention DllImport attributes, the default value is CallingCovention.Stdcall, here to change into Cdecl (c / c ++ default call mode)
