使用WMI控制Windows进程和服务

1.使用WMI控制Windows进程

本文主要介绍两种WMI的进行操作：检查进程是否存在、创建新进行

代码如下：

using System;

using System.Collections.Generic;

using System.Text;

using System.Management;

using System.Threading; 

namespace TJVictor.WMI

{

    public class Win32_Process:WMIBaseClass

    {

        #region Property

        private int timeout = ;

        public int TimeOut

        {

            get { return timeout; }

            set { timeout = value; }

        } 

        private string wqlSelect = "select * FROM Win32_Process where Name='{0}'";

        #endregion 

        #region Construction

        public Win32_Process()

            : base()

        {

            base.Connection();

        } 

        public Win32_Process(string domain, string Ip, string user, string psd)

            : base(domain, Ip, user, psd)

        {

            base.Connection();

        }

        #endregion 

        #region public function

        public bool IsProcessExist(string name)

        {

            if (!GetSelectQueryCollection(wqlSelect,name).Count.Equals())

                return true;

            return false;

        } 

        public void CreateProcess(string name)

        {

            ManagementClass processClass = new ManagementClass("Win32_Process");

            processClass.Scope = base.Scope; 

            ManagementBaseObject mbo = processClass.GetMethodParameters("Create");

            mbo["CommandLine"] = string.Format(name);

            ManagementBaseObject result = processClass.InvokeMethod("Create", mbo, null);

            //检测执行结果

            CheckExceptionClass.CheckProcessException(int.Parse(result["returnValue"].ToString()));

            //检测进程是否执行完成

            int tempTimeout = this.timeout;

            while (!GetSelectQueryCollection("select * FROM Win32_Process where ProcessID='{0}'",result["ProcessID"].ToString()).Count.Equals())

            {

                if (tempTimeout.Equals())

                {

                    throw new TJVictor.WMI.WmiException.ProcessException(

                        string.Format("在 {0} 上执行 {1} 操作失败，执行超时", base.Ip, name));

                }

                tempTimeout--;

                Thread.Sleep();

            }

        }

        #endregion

    }

}

2.使用WMI来控制Windows服务

本文介绍如何使用WMI来判断服务是否存在、如何创建新服务，删除服务、如何启服务、停服务

代码如下：

using System;

using System.Collections.Generic;

using System.Text;

using System.Management;

using System.Threading;

namespace TJVictor.WMI

{

    public class Win32_Service:WMIBaseClass

    {

        #region Property

        private bool completed = false;

        private int timeout = ;

        public int TimeOut

        {

            get { return timeout; }

            set { timeout = value; }

        }

        private string wqlSelect = string.Empty;

        #endregion

        #region Construction

        public Win32_Service()

            : base()

        {

            wqlSelect = "select * FROM Win32_Service where Name='{0}'";

            base.Connection();

        }

        public Win32_Service(string domain, string Ip, string user, string psd)

            : base(domain, Ip, user, psd)

        {

            wqlSelect = "select * FROM Win32_Service where Name='{0}'";

            base.Connection();

        }

        #endregion

        #region public function

        public bool IsServiceExist(string name)

        {

            if (!GetSelectQueryCollection(wqlSelect,name).Count.Equals())

                return true;

            return false;

        }

        public void StartService(string name)

        {

            if(!IsServiceExist(name))

                throw new TJVictor.WMI.WmiException.ServiceException(string.Format("{0} 服务不存在",name));

            object result = string.Empty;

            ManagementObjectSearcher mos = GetObjectSearcher(wqlSelect, name);

            foreach (ManagementObject mo in mos.Get())

            {

                result = mo.InvokeMethod("StartService", null);

                break;

            }

            CheckExceptionClass.CheckServiceException(int.Parse(result.ToString()));

            TestServiceState(mos, "Running", string.Format("{0} 服务在 {1} 机器上启动失败，启动超时",name,base.Ip));

        }

        public void StopService(string name)

        {

            if (!IsServiceExist(name))

                throw new TJVictor.WMI.WmiException.ServiceException(string.Format("{0} 服务不存在", name));

            object result = string.Empty;

            ManagementObjectSearcher mos = GetObjectSearcher(wqlSelect, name);

        }

            string serviceType)

        {

            if(IsServiceExist(name))

                throw new TJVictor.WMI.WmiException.ServiceException(string.Format("{0} 服务已经存在",name));

            int tempTimeout = this.timeout;

            ManagementClass processClass = new ManagementClass("Win32_Service");

            processClass.Scope = base.Scope;

            string method = "Create";

            ManagementBaseObject inputArgs = processClass.GetMethodParameters(method);

            inputArgs["Name"] = name;
