在Windows中，如何枚举并从另一个窗口的控件中获取文本？

using System;
using System.Windows.Automation;

namespace UIAutomationExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // 获取目标窗口的AutomationElement
            AutomationElement targetWindow = AutomationElement.RootElement.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "窗口标题"));

            // 枚举窗口中的所有控件
            foreach (AutomationElement control in targetWindow.FindAll(TreeScope.Descendants, Condition.TrueCondition))
            {
                // 获取控件的文本
                object textPattern;
                if (control.TryGetCurrentPattern(TextPattern.Pattern, out textPattern))
                {
                    TextPattern textPatternInstance = (TextPattern)textPattern;
                    AutomationElement textElement = textPatternInstance.DocumentRange.GetEnclosingElement();
                    Console.WriteLine(textElement.Current.Name + ": " + textElement.Current.AutomationId);
                }
            }
        }
    }
}
