C#通过wmi读取系统信息

 需要监控服务器的一些系统信息，可以通过wmi接口进行数据读取：

/// <summary>
        ///  获取数据
        /// </summary>
        public static void get()
        {

            ManagementPath pathSearch = new ManagementPath("\\\\122.224.1.12\\Root\\CIMV2");
            ManagementScope scope = new ManagementScope(pathSearch);
            scope.Options.Username = "user";
            scope.Options.Password = "pwd";

            SelectQuery select = new SelectQuery("select * from win32_logicaldisk");

            //SelectQuery select = new SelectQuery("SELECT * FROM Win32_NTLogEvent where TimeWritten>='2011-1-3'  and Logfile='SYSTEM'");

            ManagementObjectSearcher search = new ManagementObjectSearcher(select);
            search.Scope = scope;

            int i = 0;
            foreach (ManagementObject obj in search.Get())
            {
                if (obj["DriveType"].ToString() != "3")
                    continue;
                Console.WriteLine(obj["Name"].ToString());
                Console.WriteLine(obj["VolumeName"].ToString());
                Console.WriteLine(obj["Size"].ToString());
                Console.WriteLine(obj["FreeSpace"].ToString());

                ////if (obj["EventType"].ToString() != "1")
                ////    continue;
                //Console.WriteLine(obj["Message"].ToString());
                ////Console.WriteLine(obj["VolumeName"].ToString());
                ////Console.WriteLine(obj["Size"].ToString());
                ////Console.WriteLine(obj["FreeSpace"].ToString());
            }
                
        
        }



        /// <summary>
        ///  判断是32位系统还是64位系统
        /// </summary>
        /// <returns></returns>
        public static string Detect3264()
        {
            ManagementPath pathSearch = new ManagementPath( \\\\122.224.1.12\\Root\\CIMV2 );
            ManagementScope scope = new ManagementScope(pathSearch);
            scope.Options.Username = "user";
            scope.Options.Password = "Pwd";

            SelectQuery select = new SelectQuery("select AddressWidth from Win32_Processor");
            ManagementObjectSearcher search = new ManagementObjectSearcher(select);
            search.Scope = scope;
            string addressWidth = null;
            foreach (ManagementObject oReturn in search.Get())
            {
                addressWidth = oReturn["AddressWidth"].ToString();
            }

            return addressWidth;
        }

通过wmi接口远程访问有安全隐患，解决方法：

1.IP安全策略，需要开启wmi服务和135端口。

2.防火墙过滤，和Ip策略类似

遇到的问题

返回：“没有发现指定的此对象导出者”。

在本地机器的目录：C:\WINDOWS\system32\drivers\etc，在此目录下的hosts文件中增加一行：<目标机器ip>    <目标机器计算机名>
