公司员工没有管理员权限怎么办 C#文件夹、文件添加权限 C#读取windows系统日志 C#设置环境变量

在xx工作快一年了，像xx这样的一些大公司 一般用户都没有管理员权限是一个头疼的事情。其实一般情况下页没什么，有时候还真是比较麻烦。不过xx自己有一个播发程序 里面打开的程序都具有管理员权限，如vs2010，sql2008，利用这个播发程序可以安装某些软件。

对于开发人员播发程序不太够啊，所以很多时候可以写C#代码来实现

例如 安装软件  Process.Start(path);

删除文件夹

   void DeleteDirectory(string path)
        {
            DirectoryInfo dir = new DirectoryInfo(path);
            foreach (var item in dir.GetDirectories())
            {
                item.Delete(true);

            }
            dir.Delete(true);
        }

设置环境变量

        /// <summary>
        /// 设置windows环境变量
        /// </summary>
        /// <param name="name">变量名称</param>
        /// <param name="value">变量值</param>
        public static void SetEnvironmentVariable(string name, string value)
        {
            RegistryKey regLocalMachine = Registry.LocalMachine;
            RegistryKey regSYSTEM = regLocalMachine.OpenSubKey("SYSTEM", true);//打开HKEY_LOCAL_MACHINE下的SYSTEM
            RegistryKey regControlSet001 = regSYSTEM.OpenSubKey("ControlSet001", true);
            RegistryKey regControl = regControlSet001.OpenSubKey("Control", true);
            RegistryKey regManager = regControl.OpenSubKey("Session Manager", true);
            RegistryKey regEnvironment = regManager.OpenSubKey("Environment", true);
            regEnvironment.SetValue(name, value);
        }

给文件夹、文件添加权限

        // <summary>
        /// Adds an ACL entry on the specified directory for the specified account.
        /// This function was taken directly from MSDN.  It adds security rights to a folder
        /// </summary>
        /// <param name="FileName"></param>
        /// <param name="Account">like @"BUILTIN\Administrators" or @"BUILTIN\Users" </param>
        /// <param name="Rights">like FileSystemRights.FullControl</param>
        /// <param name="ControlType">like AccessControlType.Allow</param>
        ///

        public static void AddDirectorySecurity(string FileName, string Account, FileSystemRights Rights, AccessControlType ControlType)
        {
            // Create a new DirectoryInfo object.
            DirectoryInfo dInfo = new DirectoryInfo(FileName);

            // Get a DirectorySecurity object that represents the
            // current security settings.
            DirectorySecurity dSecurity = dInfo.GetAccessControl();

            // Add the FileSystemAccessRule to the security settings.
            dSecurity.AddAccessRule(new FileSystemAccessRule(Account, Rights, ControlType));

            // Set the new access settings.
            dInfo.SetAccessControl(dSecurity);
        }

        /// <summary>
        /// Adds an ACL entry on the specified directory for the specified account.
        /// This function was taken directly from MSDN.  It adds security rights to a file
        /// </summary>
        /// <param name="FileName"></param>
        /// <param name="Account">like @"BUILTIN\Administrators" or @"BUILTIN\Users" </param>
        /// <param name="Rights">like FileSystemRights.FullControl</param>
        /// <param name="ControlType">like AccessControlType.Allow</param>
        public static void AddFileSecurity(string FileName, string Account, FileSystemRights Rights, AccessControlType ControlType)
        {
            // Create a new FileInfo object.
            FileInfo fInfo = new FileInfo(FileName);

            // Get a FileSecurity object that represents the
            // current security settings.
            FileSecurity fSecurity = fInfo.GetAccessControl();

            // Add the FileSystemAccessRule to the security settings.
            fSecurity.AddAccessRule(new FileSystemAccessRule(Account,
                                                            Rights,
                                                            ControlType));

            // Set the new access settings.
            fInfo.SetAccessControl(fSecurity);
        }

读取windows日志

        /// <summary>
        /// 读取windows 系统日志
        /// </summary>
        /// <returns></returns>
        public static string ReadWindowsLog()
        {
            string[] logs = new string[] { "Application", "System", "Security" };

            /*清空所有日志*/
            //EventLog eventlog = new EventLog();
            //foreach (var item in logs)
            //{
            //    eventlog.Log = item;
            //    eventlog.Clear();  
            //}

            /*清空所有日志*/

            StringBuilder sb = new StringBuilder();

            foreach (string log in logs)
            {
                EventLog myLog = new EventLog();
                myLog.Log = log;
                //myLog.MachineName = "rondi-agt0qf9op";
                foreach (EventLogEntry entry in myLog.Entries)
                {
                    //EventLogEntryType枚举包括：
                    //Error 错误事件。
                    //FailureAudit 失败审核事件。
                    //Information 信息事件。
                    //SuccessAudit 成功审核事件。
                    //Warning 警告事件。
                    if (entry.EntryType == EventLogEntryType.Error || entry.EntryType == EventLogEntryType.Warning)
                    {
                        sb.Append(log);
                        sb.Append(entry.EntryType.ToString());
                        sb.Append(entry.TimeWritten.ToString());
                        sb.Append(entry.Message + "\r\n");
                    }
                }
            }
            return sb.ToString();
        }

对与我们开发人员，读取日志和给文件、文件夹添加权限是很重要的。这天帮同事在计算机上配置了一个iis站点，不站点为什么已访问该站点相应的应用程序池 就停止了，我们怀疑于操作系统有关。可是不能查看日志，最后只有把it叫过来查看日志，发现什么文件权限不过，再添加权限iis站点就可以访问了。

欢迎大家纠正
