查找並關閉多個窗口

Question

我在下面找到的代碼找到一個以特定「窗口名稱」開頭並關閉它的窗口。但是同時打開多個同名窗口。我需要同時關閉所有這些。我如何去做這件事？

foreach (Process proc in Process.GetProcesses()) 
{ 
    string toClose = null; 

    if (proc.MainWindowTitle.StartsWith("untitled")) 
    { 
     toClose = proc.MainWindowTitle; 

     int hwnd = 0; 

     //Get a handle for the Application main window 
     hwnd = FindWindow(null, toClose); 

     //send WM_CLOSE system message 
     if (hwnd != 0) 
      SendMessage(hwnd, WM_CLOSE, 0, IntPtr.Zero);   
    } 
} 

Answer 1

您可以使用Process.GetProcessesByName方法返回Process類型的數組。例如，如果您打開了2個未命名實例，它將返回一個包含2個進程的數組。

希望這有助於:)
