1、 主要使用到的组件有System.Management.dll
2、 主要类为 ：ManagementScope
连接远程服务器示例代码：
1 private const string PROPERTY_CAPACITY = "Capacity"; 2 private const string PROPERTY_AVAILABLE_BYTES = "AvailableBytes"; 3 private const string PROPERTY_PROCESS_ID = "ProcessId"; 4 private const string PROPERTY_PROCESS_NAME = "Name"; 5 private const string PROPERTY_WORKING_SET_SIZE = "WorkingSetSize"; 6 7 8 ConnectionOptions Conn = new ConnectionOptions(); 9 //设定用于WMI连接操作的用户名 10 Conn.Username = "用户名"; 11 //设定用户的口令 12 Conn.Password = "密码"; 13 ManagementScope Ms = new ManagementScope("\\\\ip\\root\\cimv2", Conn); 14 Ms.Connect(); |
具体查询举例：
1 var query1 = new SelectQuery("SELECT * FROM Win32_PhysicalMemory"); 2 var query2 = new SelectQuery("SELECT * FROM Win32_PerfRawData_PerfOS_Memory"); 3 var query3 = new SelectQuery("SELECT * FROM Win32_Processor"); 4 var query4 = new SelectQuery("SELECT * FROM Win32_Process"); 5 6 var searcher1 = new ManagementObjectSearcher(Ms, query1); 7 var searcher2 = new ManagementObjectSearcher(Ms, query2); 8 var searcher3 = new ManagementObjectSearcher(Ms, query3); 9 var searcher4 = new ManagementObjectSearcher(Ms, query4); |
查询内存和CPU：
1 var capacity = 0.0; 2 var free = 0.0; 3 var cpu = 0.0; 4 // 2048 5 foreach (var o in searcher1.Get()) 6capacity += (double)Convert.ToUInt64(o[PROPERTY_CAPACITY]) / (double)(1024 * 1024); 7 foreach (var o in searcher2.Get()) 8 free += (double)Convert.ToUInt64(o[PROPERTY_AVAILABLE_BYTES]) / (double)(1024 * 1024); 9 foreach (var o in searcher3.Get()) 10 { 11 if (o["LoadPercentage"] != null) 12 { 13 cpu = long.Parse(o["LoadPercentage"].ToString()); 14 } 15 else { 16 cpu = 0; 17 } 18 } |
举例远程重启某个进程（部分示例代码）：
1 ConnectionOptions Conn = new ConnectionOptions(); 2 Conn.Username = userName; //设定用户的口令 3 Conn.Password = pwd; 4 Ms = new ManagementScope("\\\\" + ip + "\\root\\cimv2", Conn); 5 Ms.Connect(); 6 ManagementClass processClass = new ManagementClass(Ms, new ManagementPath("Win32_Process"), null); 7 //获得用来提供参数的对象 8 ManagementBaseObject inParams = processClass.GetMethodParameters("Create"); 9 //设定命令行参数 10 inParams["CommandLine"] = path;// @"需要启动的进程路径"; 11 //执行程序 12 ManagementBaseObject outParams = processClass.InvokeMethod("Create", inParams, null); |
Other、可以用程序操作批处理文件(.bat)来查询进程或者是关闭进程：
例如查询所有进程 ：tasklist /S ip /U 用户名 /P 密码
关闭某个进程：
taskkill /S ip /U用户名/P 密码 /IM 需要关闭的进程名
