Qihangnet's Blog! - 一个简单的C#程序（Console）

Wednesday, March 23, 2005

刚学C#写的一个小程序，来列举本地的进程，两种模式：
1.列举出进程的starttime和title。
2.列举出进程的执行文件完全路径。
编译环境：Windows 2003+Microsoft.NET Framework v1.1.4322
附上源码：

程序代码：

//List all processes on local system(two modes)

//Kill the specified process

using System;
using System.Diagnostics;
using System.Management;
public class PK
{
    public static void Main(string[] args)
    {
       if(args.Length != 1)
       {
        help();
       }
       else
       {
        switch(args[0])
        {
         case "/t":
          psst();
         break;
         case "/p":
          psph();
         break;
         default:
          kill(args[0]);
         break;
        }
       }
    }
    //Show the Usage

    private static void help()
    {
     Console.WriteLine("Local System Process Lister and Killer V1.0 (2004-9-25 C#) ");
     Console.WriteLine("Code by sfzhi msn:idazhi@hotmail.com");
     Console.WriteLine();
     Console.WriteLine("Usage:    pk    ");
     Console.WriteLine("Options:  /t         - Show the starttime and title of all processes");
     Console.WriteLine("          /p         - Show the path to executable file of all processes");
     Console.WriteLine("          PID/Name   - Kill the specified process");
    }
    //Show the starttime and title of all processes

    private static void psst()
    {
        Process[] procList = Process.GetProcesses();
        Console.WriteLine("{0,-6}{1,-12}{2,-22}{3}","PID","Process","StartTime","Title");
        for (int i=0;i<procList.Length-1;i++)
        {
            string strProcName = procList[i].ProcessName;
            int iProcID = procList[i].Id;
            DateTime dProcStTime = procList[i].StartTime;
            string strProcTitle = procList[i].MainWindowTitle;
            Console.WriteLine("{0,-6}{1,-12}{2,-22}{3}",iProcID,strProcName,dProcStTime,strProcTitle);
        }
    }
    //Show the path to executable file of all processes

    private static void psph()
    {
        Process[] p = Process.GetProcesses();
         ManagementObjectSearcher searcher;
        ManagementObjectCollection collection;
        searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Process");
        collection = searcher.Get();
        Console.WriteLine("{0,-5}{1,-16}{2}","PID","ProcName","ProcessPath");
        foreach (ManagementObject service in collection)
        {
         Console.WriteLine("{0,-5}{1,-16}{2}",service["ProcessID"],service["Name"],service["ExecutablePath"]);
        }
     }
     //Terminate the specified process

     private static void kill(string idname)
       {
           Process[] all = Process.GetProcesses();
           foreach(Process p in all)
           {
             if(p.Id.ToString() == idname || p.ProcessName == idname)
             {
                  p.Kill();
                  p.Close();
                  Console.WriteLine("Process {0} was terminated successfully",idname);
              }
           }
       }
}
