1.功能

鼠标点到应用图标，显示该进程号，并可以强制关闭此进程

2.程序

using System; using System.Diagnostics; using System.Drawing; using System.Runtime.InteropServices; using System.Windows.Forms; namespace ProcessKiller { public partial class MainForm : Form { // Windows API 导入 [DllImport("user32.dll")] private static extern IntPtr WindowFromPoint(Point point); [DllImport("user32.dll")] private static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint processId); [DllImport("user32.dll")] private static extern int GetWindowText(IntPtr hWnd, System.Text.StringBuilder text, int count); [DllImport("user32.dll")] private static extern int GetWindowTextLength(IntPtr hWnd); [DllImport("user32.dll")] private static extern bool IsWindowVisible(IntPtr hWnd); [DllImport("user32.dll")] private static extern IntPtr GetShellWindow(); // 控件声明 private Label lblStatus; private Button btnKill; private Button btnRefresh; private ListBox lstProcesses; private Timer timer; private uint selectedProcessId = 0; public MainForm() { InitializeComponent(); StartMouseHook(); } private void InitializeComponent() { this.Text = "进程终结者 - 点击图标显示PID并强制关闭"; this.Size = new Size(400, 500); this.StartPosition = FormStartPosition.CenterScreen; this.TopMost = true; // 状态标签 lblStatus = new Label() { Location = new Point(12, 12), Size = new Size(360, 50), Text = "将鼠标移动到任意窗口或任务栏图标上...", BackColor = Color.LightYellow, BorderStyle = BorderStyle.FixedSingle }; // 进程列表 lstProcesses = new ListBox() { Location = new Point(12, 70), Size = new Size(360, 300), Font = new Font("Consolas", 9) }; // 关闭按钮 btnKill = new Button() { Text = "强制关闭选中的进程", Location = new Point(12, 380), Size = new Size(170, 40), BackColor = Color.IndianRed, Enabled = false }; btnKill.Click += BtnKill_Click; // 刷新进程列表按钮 btnRefresh = new Button() { Text = "刷新进程列表", Location = new Point(202, 380), Size = new Size(170, 40), BackColor = Color.LightBlue }; btnRefresh.Click += BtnRefresh_Click; // 定时器用于实时更新鼠标下的进程信息 timer = new Timer(); timer.Interval = 200; // 200毫秒检测一次 timer.Tick += Timer_Tick; this.Controls.Add(lblStatus); this.Controls.Add(lstProcesses); this.Controls.Add(btnKill); this.Controls.Add(btnRefresh); } private void StartMouseHook() { timer.Start(); } private void Timer_Tick(object sender, EventArgs e) { Point cursorPos = Control.MousePosition; IntPtr hWnd = WindowFromPoint(cursorPos); if (hWnd != IntPtr.Zero) { // 获取窗口标题 int textLen = GetWindowTextLength(hWnd); string windowTitle = ""; if (textLen > 0) { System.Text.StringBuilder sb = new System.Text.StringBuilder(textLen + 1); GetWindowText(hWnd, sb, sb.Capacity); windowTitle = sb.ToString(); } // 获取进程ID GetWindowThreadProcessId(hWnd, out uint pid); // 更新状态栏 if (pid > 0) { try { Process proc = Process.GetProcessById((int)pid); string processName = proc.ProcessName; lblStatus.Text = $"当前指向: {windowTitle} (窗口句柄: {hWnd})\n进程名: {processName} PID: {pid}"; selectedProcessId = pid; btnKill.Enabled = true; } catch { lblStatus.Text = $"指向对象无法获取进程信息 (PID: {pid})"; selectedProcessId = 0; btnKill.Enabled = false; } } else { lblStatus.Text = $"指向: {windowTitle} (无法获取进程ID)"; selectedProcessId = 0; btnKill.Enabled = false; } } } private void BtnKill_Click(object sender, EventArgs e) { if (selectedProcessId == 0) { MessageBox.Show("没有选中的进程", "提示", MessageBoxButtons.OK, MessageBoxIcon.Warning); return; } try { Process processToKill = Process.GetProcessById((int)selectedProcessId); DialogResult result = MessageBox.Show( $"确定要强制关闭进程 \"{processToKill.ProcessName}\" (PID: {selectedProcessId}) 吗？\n\n这将立即终止该进程及其所有线程。", "确认关闭", MessageBoxButtons.YesNo, MessageBoxIcon.Warning); if (result == DialogResult.Yes) { processToKill.Kill(); processToKill.WaitForExit(1000); MessageBox.Show($"进程 {processToKill.ProcessName} (PID: {selectedProcessId}) 已被终止。", "成功", MessageBoxButtons.OK, MessageBoxIcon.Information); selectedProcessId = 0; btnKill.Enabled = false; BtnRefresh_Click(null, null); // 刷新列表 } } catch (Exception ex) { MessageBox.Show($"无法终止进程: {ex.Message}", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error); selectedProcessId = 0; btnKill.Enabled = false; } } private void BtnRefresh_Click(object sender, EventArgs e) { lstProcesses.Items.Clear(); Process[] processes = Process.GetProcesses(); foreach (Process proc in processes) { try { string title = string.IsNullOrEmpty(proc.MainWindowTitle) ? "[无窗口]" : proc.MainWindowTitle; lstProcesses.Items.Add($"{proc.ProcessName,-30} PID:{proc.Id,-8} 窗口:{title}"); } catch { lstProcesses.Items.Add($"{proc.ProcessName,-30} PID:{proc.Id,-8} [无法获取窗口信息]"); } } lstProcesses.Items.Add("----------------------------------------------"); lstProcesses.Items.Add("提示: 将鼠标移动到任务栏图标或窗口上即可检测"); } protected override void OnFormClosed(FormClosedEventArgs e) { timer.Stop(); base.OnFormClosed(e); } } static class Program { [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MainForm()); } } }

3.使用方法与功能说明：

实时检测：程序运行后，将鼠标移动到任何窗口标题栏或任务栏图标上，状态栏会立即显示该窗口的标题、所属进程名称和进程ID (PID)。
强制关闭：
- 当鼠标指向一个可识别的进程窗口时，窗口底部的“强制关闭选中的进程”按钮会被启用。
- 点击该按钮后，程序会弹出确认对话框，确认后将立即终止该进程。
- 注意：关闭系统关键进程（如explorer.exe、csrss.exe等）可能导致系统不稳定，请谨慎操作。
进程列表：右侧的进程列表显示了当前系统中所有正在运行的进程及其PID，方便您查看和选择。
