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 = 30;
        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(0))
                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(0))
            {
                if (tempTimeout.Equals(0))
                {
                    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(1000);
            }
        }
        #endregion
    }
}
