Hi,

I have been writing some Pinvoke code for lower level WinAPI Access Control functions. I have a pointer to Privileges associated with my access token from the TOKEN_ACCESS_INFORMATION and I am looking at the privileges. I have working code but decided to refactor part of it to a generic method that given a pointer to a structure with a count property could retrieve the array of items associated with the count. The problem is that the following code inside the generic method ( first line of code ) that is passed the pointer does not return a consistent result. From within the method that obtained the pointer it is as expected.

uint uiPrivilegeCount = (uint)Marshal.PtrToStructure(privilegePointer, typeof(uint));

Many thanks

Tony
