Directory.GetAccessControl的代码示例1 - GetServiceDirectorySecurity()

    using System.IO;

        private DirectorySecurity GetServiceDirectorySecurity(string serviceDataRootPath)
        {
            DirectorySecurity serviceDataRootSecurity;
            if (Directory.Exists(serviceDataRootPath))
            {
                this.tracer.RelatedInfo($"{nameof(this.GetServiceDirectorySecurity)}: {serviceDataRootPath} exists, modifying ACLs.");
                serviceDataRootSecurity = Directory.GetAccessControl(serviceDataRootPath);
            }
            else
            {
                this.tracer.RelatedInfo($"{nameof(this.GetServiceDirectorySecurity)}: {serviceDataRootPath} does not exist, creating new ACLs.");
                serviceDataRootSecurity = new DirectorySecurity();
            }

            // Protect the access rules from inheritance and remove any inherited rules
            serviceDataRootSecurity.SetAccessRuleProtection(isProtected: true, preserveInheritance: false);

            // Remove any existing ACLs and add new ACLs for users and admins
            WindowsFileSystem.RemoveAllFileSystemAccessRulesFromDirectorySecurity(serviceDataRootSecurity);
            WindowsFileSystem.AddUsersAccessRulesToDirectorySecurity(serviceDataRootSecurity, grantUsersModifyPermissions: false);
            WindowsFileSystem.AddAdminAccessRulesToDirectorySecurity(serviceDataRootSecurity);

            return serviceDataRootSecurity;
        }
