获取所有打开的窗口的标题

像这样：

using System.Diagnostics;Process[] processlist = Process.GetProcesses();foreach (Process process in processlist){    if (!String.IsNullOrEmpty(process.MainWindowTitle))    {        Console.WriteLine("Process: {0} ID: {1} Window title: {2}", process.ProcessName, process.Id, process.MainWindowTitle);    }}
