如何使用.NET枚举属于特定进程的所有窗口？

我怎么能find所有的窗口使用C＃特定的进程创build？

UPDATE

我需要使用应用程序的PID （进程ID）枚举属于特定进程的所有窗口。

使用Win32 API EnumWindows （如果你想要子窗口EnumChildWindows ）），或者你也可以使用EnumThreadWindows 。

[DllImport("user32.dll",CharSet=CharSet.Auto,SetLastError=true)] public static extern bool EnumWindows(EnumThreadWindowsCallback callback,IntPtr exTradata);

然后使用Win32 API GetwindowThreadProcessId检查每个窗口属于哪个进程

[DllImport("user32.dll",SetLastError=true)] public static extern int GetwindowThreadProcessId(HandleRef handle,out int processId);

delegate bool EnumThreadDelegate(IntPtr hWnd,IntPtr lParam); [DllImport("user32.dll")] static extern bool EnumThreadWindows(int dwThreadId,EnumThreadDelegate lpfn,IntPtr lParam); static IEnumerable<IntPtr> EnumerateProcessWindowHandles(int processId) { var handles = new List<IntPtr>(); foreach (Processthread thread in Process.GetProcessById(processId).Threads) EnumThreadWindows(thread.Id,(hWnd,lParam) => { handles.Add(hWnd); return true; },IntPtr.Zero); return handles; }

和样本用法：

private const uint WM_GETTEXT = 0x000D; [DllImport("user32.dll",CharSet = CharSet.Auto)] static extern IntPtr SendMessage(IntPtr hWnd,uint Msg,int wParam,StringBuilder lParam); [STAThread] static void Main(string[] args) { foreach (var handle in EnumerateProcessWindowHandles( Process.GetProcessesByName("explorer").First().Id)) { StringBuilder message = new StringBuilder(1000); SendMessage(handle,WM_GETTEXT,message.Capacity,message); Console.WriteLine(message); } }

古代的线程，但它让我开始，所以这里有一个小的实用程序功能，将找到一个匹配lambda（谓语）的子窗口。 易于更改返回列表。 在谓词中处理多个标准。

public delegate bool Win32Callback(IntPtr hwnd,IntPtr lParam); [DllImport("user32.Dll")] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool EnumChildWindows(IntPtr parentHandle,Win32Callback callback,IntPtr lParam); /// <summary> /// Find a child window that matches a set of conditions specified as a Predicate that receives hWnd. Returns IntPtr.Zero /// if the target window not found. Typical search criteria would be some combination of window attributes such as /// ClassName,Title,etc.,all of which can be obtained using API functions you will find on pinvoke.net /// </summary> /// <remarks> /// <para>Example: Find a window with specific title (use Regex.IsMatch for more sophisticated search)</para> /// <code lang="C#"><![CDATA[var foundHandle = Win32.FindWindow(IntPtr.Zero,ptr => Win32.GetwindowText(ptr) == "Dashboard");]]></code> /// </remarks> /// <param name="parentHandle">Handle to window at the start of the chain. Passing IntPtr.Zero gives you the top level /// window for the current process. To get windows for other processes,do something similar for the FindWindow /// API.</param> /// <param name="target">Predicate that takes an hWnd as an IntPtr parameter,and returns True if the window matches. The /// first match is returned,and no further windows are scanned.</param> /// <returns> hWnd of the first found window,or IntPtr.Zero on failure </returns> public static IntPtr FindWindow(IntPtr parentHandle,Predicate<IntPtr> target) { var result = IntPtr.Zero; if (parentHandle == IntPtr.Zero) parentHandle = Process.GetCurrentProcess().MainWindowHandle; EnumChildWindows(parentHandle,(hwnd,param) => { if (target(hwnd)) { result = hwnd; return false; } return true; },IntPtr.Zero); return result; }

例

var foundHandle = Win32.FindWindow(IntPtr.Zero,ptr => Win32.GetwindowText(ptr) == "Dashboard");
