查找/列出进程很容易，但干掉进程得借助系统命令ntsd.exe，详细用法见下面的代码 :
using System;
using System.Diagnostics;
using System.Windows.Forms;
namespace ProcessDemo
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
this.linkLabel1.links.Add(0, linkLabel1.Text.Length, "http://yjmyzz.cnblogs.com/");
}
private void linkLabel1_linkClicked(object sender, linkLabellinkClickedEventArgs e)
{
this.linkLabel1.links[linkLabel1.links.IndexOf(e.link)].Visited = true;
string target = e.link.linkData as string;
if (target != null && target.StartsWith("http://"))
{
Process.Start(target);
}
}
///
/// 列出所有可访问进程
///
///
///
private void btnList_Click(object sender, EventArgs e)
{
Process[] processes;
processes = Process.GetProcesses();
string str = "";
foreach (Process p in processes)
{
try
{
str = p.ProcessName;
this.lst1.Items.Add("名称：" + p.ProcessName + "，启动时间：" + p.StartTime.ToShortTimeString() + "，进程ID：" + p.Id.ToString() );
}
catch (Exception ex)
{
this.lst1.Items.Add(ex.Message.ToString());//某些系统进程禁止访问，所以要加异常处理
}
}
}
private void btnFind_Click(object sender, EventArgs e)
{
txtFind.Text = txtFind.Text.Trim().ToLower();
if (txtFind.Text.Length > 0)
{
Process[] arrP = Process.GetProcesses();
foreach (Process p in arrP)
{
try
{
if (p.ProcessName.ToLower() == txtFind.Text)
{
MessageBox.Show(txtFind.Text + " 找到了，PID为 " + p.Id.ToString());
return;
}
}
catch { }
}
MessageBox.Show("未找到该进程，请检查输入!");
}
}
private void btnKill_Click(object sender, EventArgs e)
{
txtFind.Text = txtFind.Text.Trim().ToLower();
int pid = -1;
if (txtFind.Text.Length > 0)
{
Process[] arrP = Process.GetProcesses();
foreach (Process p in arrP)
{
try
{
if (p.ProcessName.ToLower() == txtFind.Text)
{
pid = p.Id;
break;
}
}
catch { }
}
if (pid != -1)
{
RunCmd("ntsd -c q -p " + pid);
}
}
}
///
/// 运行DOS命令
/// DOS关闭进程命令(ntsd -c q -p PID )PID为进程的ID
///
///
///
public string RunCmd(string command)
{
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.Arguments = "/c " + command;
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.Start();
return p.StandardOutput.ReadToEnd();
}
}
}
另外ntsd.exe在windows vista以上的版本(包括windows 2008)上，出于安全考虑已经被MS给去掉了，但我们可以直接从xp下复制过来继续使用
