How can I get the current user-GUID in SharePoint 2010?

问题

How can I get the GUID of the current user in SharePoint 2010 with C#? The following is my code:

    public string readAndEncodeGUID()
    {
        Guid userGuid = Guid.Empty;

        SPSecurity.RunWithElevatedPrivileges(delegate()
        {                
            SPWeb readWeb = SPContext.Current.Web;
            SPUser currUser = SPContext.Current.Web.CurrentUser;
            userGuid = new Guid(currUser.RawSid);
        });

        //Variable = encode USER-GUID
        return userGuid.ToString();
    }

The RawSid get not the right "number".

thanks

Check out the SPUser members. You should use either the ID property or the Sid depending on what you want. RawSid is the system ID of the user in binary format.
