[C#] 透過行程名稱/行程ID操作程式程式

判斷程式是否執行

1. public bool IsWindowExist(IntPtr handle)
   
2. {
   
3.     return (!(GetWindow(new HandleRef(this, handle), 4) != IntPtr.Zero) && IsWindowVisible(new HandleRef(this, handle)));
   
4. }
   
5. 
   
6. [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
   
7. public static extern IntPtr GetWindow(HandleRef hWnd, int uCmd);
   
8. 
   
9. [DllImport("user32.dll", CharSet = CharSet.Auto)]
   
10. public static extern bool IsWindowVisible(HandleRef hWnd);

根據處理緒Handle查找程式

1. public IntPtr GetWindowHandle(int processId)
   
2. {
   
3.     var windowHandle = IntPtr.Zero;
   
4.     EnumThreadwindowsCallback windowsCallback = new EnumThreadWindowsCallback(FindMainWindow);
   
5.     EnumWindows(windowsCallback, IntPtr.Zero);
   
6. 
   
7.     GC.KeepAlive(windowsCallback);
   
8. 
   
9.     bool FindMainWindow(IntPtr handle, IntPtr extraParameter)
   
10.     {
    
11.         int num;
    
12.         GetWindowThreadProcessId(new HandleRef(this, handle), out num);
    
13.         if (num == processId && IsWindowExist(handle))
    
14.         {
    
15.             windowHandle = handle;
    
16.             return true;
    
17.         }
    
18.         return false;
    
19.     }
    
20. 
    
21.     return windowHandle;
    
22. }
    
23. 
    
24. public delegate bool EnumThreadWindowsCallback(IntPtr hWnd, IntPtr lParam);
    
25. 
    
26. [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    
27. public static extern bool EnumWindows(EnumThreadWindowsCallback callback, IntPtr extraData);
    
28. 
    
29. [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    
30. public static extern int GetWindowThreadProcessId(HandleRef handle, out int processId);

根據行程ID關閉程式

1. public void CloseWindow(int processId)
   
2. {
   
3.     var mwh = GetWindowHandle(processId);
   
4.     SendMessage(mwh, MW_CLOSE, 0, 0);
   
5. }
   
6. const int MW_CLOSE = 0x0010;
   
7. 
   
8. [DllImport("User32.dll", EntryPoint = "SendMessage")]
   
9. public static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);

關閉所有此行程名稱的程式

1. public void CloseAllWindows(string processName)
   
2. {
   
3.     Process[] processList = Process.GetProcessesByName(processName);
   
4.     foreach (Process process in processList)
   
5.     {
   
6.         CloseMainWindow(process.Id);
   
7.     }
   
8. }

直接關閉所有行程

1. public static bool CloseAllProcesses(string processName)
   
2. {
   
3.     try
   
4.     {
   
5.         Process[] psEaiNotes = Process.GetProcessesByName(processName);
   
6.         foreach (Process psEaiNote in psEaiNotes)
   
7.         {
   
8.             psEaiNote.Kill();
   
9.         }
   
10.     }
    
11.     catch
    
12.     {
    
13.         return false;
    
14.     }
    
15.     return true;
    
16. }

重新啟動程序

1. string appFileName = currentClientProcess.MainModule.FileName;
   
2. 
   
3. Process newClient = new Process();
   
4. newClient.StartInfo.FileName = appFileName;
   
5. // 設定執行程序的開始目錄
   
6. newClient.StartInfo.WorkingDirectory = System.Windows.Forms.Application.ExecutablePath;
   
7. 
   
8. // 執行程序
   
9. currentClientProcess.Kill();
   
10. newClient.Start();
