kentico检查当前授权用户，是否为admin角色

https://docs.kentico.com/k11/custom-development/user-internals-and-api/checking-permissions-using-the-api

 private bool CheckPrivilegeLevel()
    {
        // Gets the user object
        UserInfo user = MembershipContext.AuthenticatedUser;

        if (user != null)
        {
            // Checks whether the user has the Admin privilege level or higher
            if (user.CheckPrivilegeLevel(UserPrivilegeLevelEnum.Admin, SiteContext.CurrentSiteName))
            {
                // Perform an action according to the result
                return true;
            }
        }

        return false;

    }

在page load的时候，检查权限，如果没权限，就403终止

 protected void Page_Load(object sender, EventArgs e)
    {
        bool flag = CheckPrivilegeLevel();
        if (!flag)
        {
            Response.StatusCode = (int)System.Net.HttpStatusCode.Forbidden;
            Response.Flush();
            Response.End();
        }
        else
        {
            // Registers the default CSS and JavaScript files onto the page (used to style the UniGrid)
            CssRegistration.RegisterBootstrap(Page);
            ScriptHelper.RegisterBootstrapScripts(Page);

            MainGrid.DataSource = GetNoUseWebpartReplacement();
        }
    }
