用C#+WMI实现获取w3wp进程对应的应用程序池

自从用了ASP.NET2.0以后，这个问题被渐渐关注起来，目前的方法就是调用iisapp.vbs获取。

今天准备在我的文本转换工具里集成这个功能，于是，用C#实现了一下。using System;using System.Text;using System.Text.RegularExpressions;using System.Diagnostics;using System.Management;using System.Windows.Forms;

namespace TextConvertor{;/**//// <summary>;/// W3wp 的摘要说明。;/// </summary>;public class W3wp;{;;;;;private W3wp(){};;;;;public static string GetAllW3wp(string input);;;;;{;ObjectQuery oQuery = new ObjectQuery("select * from Win32_Process where Name='w3wp.exe'"); ;ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oQuery); ;ManagementObjectCollection oReturnCollection = oSearcher.Get();;string pid;;string cmdLine;;StringBuilder sb = new StringBuilder() ;;foreach(ManagementObject oReturn in oReturnCollection) ;{;;;;;;;;;;pid = oReturn.GetPropertyValue("ProcessId").ToString() ;;;;;cmdLine = (string)oReturn.GetPropertyValue("CommandLine");

string pattern = "-ap "(.*)"" ;;;;;;Regex regex = new Regex(pattern, RegexOptions.IgnoreCase) ;;;;;;Match match = regex.Match(cmdLine) ;;;;;;string appPoolName = match.Groups[1].ToString() ;;;;;;sb.AppendFormat("W3WP.exe PID: {0}AppPoolId:{1}rn", pid, appPoolName );;}

return sb.ToString();;;;;;};}}

实现的原理和VBScript简直一模一样。
