AccessViolationException trying to get token privileges

[sommafa]

Hello,
It often happens to me, when the function AccessToken.GetTokenPrivileges is called, that I receive an AccessViolation Exception

Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException
   at System.Runtime.InteropServices.Marshal.PtrToStructureHelper(IntPtr, System.Object, Boolean)
   at System.Runtime.InteropServices.Marshal.PtrToStructure(IntPtr, System.Type)
   at AccessToken.GetTokenPrivileges(IntPtr)

It refers to this line of code:

RunasCs/RunasCs.cs

Line 1526 in a1e47b5

TOKEN_PRIVILEGES TokenPrivileges = (TOKEN_PRIVILEGES)Marshal.PtrToStructure( TokenInformation , typeof( TOKEN_PRIVILEGES ) ) ;

Is MAYBE present a difference between size of managed and native structure?

thank you
Fabio

Hi,

please include more information to troubleshoot and reproduce the issue.

What OS version are you running on? What is the commandline of RunasCs.exe you are using that is causing the exception? In which context are you using the tool?
