查找并关闭多个窗口

本文关键字：窗口 查找 | 更新日期: 2023-09-27 18:24:54

下面的代码找到一个以特定"窗口名称"开头的窗口，然后将其关闭。然而，同时打开了多个同名窗口。我需要同时关闭所有这些。我该怎么做？

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);        
    }
}

查找并关闭多个窗口

您可以使用Process.GetProcessesByName方法，该方法返回Process类型的数组。例如，如果打开了2个无标题实例，它将返回一个由2个进程组成的数组。

有关详细信息，请参阅：http://msdn.microsoft.com/en-us/library/System.Diagnostics.Process.GetProcessesByName.aspx

希望这有帮助：）

枚举窗口并按名称查找窗口。
