Error - "Operator '|' cannot be applied to operands of type...

I'm getting this error for some reason....

"Operator '|' cannot be applied to operands of type 'WindowsService.ACCESS_MASK' and 'int' "

Code:

---

        private const Int32 SC_MANAGER_QUERY_LOCK_STATUS = 0x00010;
        private const Int32 SC_MANAGER_CONNECT = 0x00001;
        private const Int32 SC_MANAGER_CREATE_SERVICE = 0x00002;
        private const Int32 SC_MANAGER_ENUMERATE_SERVICE = 0x00004;
        private const Int32 SC_MANAGER_LOCK = 0x00008;
    private const Int32 SC_MANAGER_MODIFY_BOOT_CONFIG = 0x00020;
    private const Int32 SC_MANAGER_ALL_ACCESS = ACCESS_MASK.STANDARD_RIGHTS_REQUIRED | SC_MANAGER_CONNECT | SC_MANAGER_CREATE_SERVICE | SC_MANAGER_ENUMERATE_SERVICE | SC_MANAGER_LOCK | SC_MANAGER_QUERY_LOCK_STATUS | SC_MANAGER_MODIFY_BOOT_CONFIG;

Code:

        [Flags()]
        private enum ACCESS_MASK : uint
        {               
                DELETE = 0x10000,

                WINSTA_READSCREEN = 0x200,

                WINSTA_ALL_ACCESS = 0x37f
        }

If I remove the ACCESS_MASK.STANDARD_RIGHTS_REQUIRED, the error goes away. Why is this occuring?

Code:

---

private enum ACCESS_MASK : int

---

Does this fix it?

Instead of Int32's in the first code section, you should probably try using uint's.

Then you should be able to OR them.

I tried changing to private enum ACCESS_MASK : int but this didn't work.

I also changed all the datatypes from int32 to uint including SC_MANAGER_ALL_ACCESS but then the error changes to "Operator '|' cannot be applied to operands of type 'WindowsService.ACCESS_MASK' and 'uint' "

Ok, nevermind. LoL. I fixed it.

Code:

---

private const Int32 SC_MANAGER_ALL_ACCESS = (Int32)ACCESS_MASK.STANDARD_RIGHTS_REQUIRED | SC_MANAGER_CONNECT | SC_MANAGER_CREATE_SERVICE | SC_MANAGER_ENUMERATE_SERVICE | SC_MANAGER_LOCK | SC_MANAGER_QUERY_LOCK_STATUS | SC_MANAGER_MODIFY_BOOT_CONFIG;
