使用c#程序 添加iis网站目录的用户权限

1、放一个按钮，在单击事件里选择一个文件目录，如下：

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            CommonOpenFileDialog dialog = new CommonOpenFileDialog();
            dialog.IsFolderPicker = true;//设置为选择文件夹
            if (dialog.ShowDialog() == CommonFileDialogResult.Ok)
            {
                this.txtPath.Text = dialog.FileName;
            }
            AddSecurityControll2Folder(this.txtPath.Text);

            MessageBox.Show("添加IIS网站目录权限成功！");
        }

2、执行目录权限修改的方法，方法如下：

static void AddSecurityControll2Folder(string dirPath)
        {
            DirectoryInfo dir = new DirectoryInfo(dirPath);
            //获得该文件夹的所有访问权限
            System.Security.AccessControl.DirectorySecurity dirSecurity = dir.GetAccessControl(AccessControlSections.All);
            //设定文件ACL继承
            InheritanceFlags inherits = InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit;

            FileSystemAccessRule IIS_IUSRS_FileSystemAccessRule = new FileSystemAccessRule("IIS_IUSRS", FileSystemRights.FullControl, inherits, PropagationFlags.None, AccessControlType.Allow);
            FileSystemAccessRule IUSR_FileSystemAccessRule = new FileSystemAccessRule("IUSR", FileSystemRights.FullControl, inherits, PropagationFlags.None, AccessControlType.Allow);
            bool isModified = false;

            dirSecurity.ModifyAccessRule(AccessControlModification.Add, IIS_IUSRS_FileSystemAccessRule, out isModified);
            dirSecurity.ModifyAccessRule(AccessControlModification.Add, IUSR_FileSystemAccessRule, out isModified);
            dir.SetAccessControl(dirSecurity);
        }
