 class Program
{
    //1.GetWindowText 获取给定窗口句柄的窗口标题
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern bool SwitchToThisWindow(IntPtr hWnd, bool fAltTab);
    [STAThread]//启动单一现场
    static void Main(string[] args)
    {

        Process[] processes = Process.GetProcessesByName("WeChat");
        if (processes.Count() != 1)
        {
            Console.WriteLine("微信未启动或启动多个微信");
        }
        else
        {
            //1.附加到微信进程
            using (var app = Application.Attach(processes.First().Id))
            {
                using (var automation = new UIA3Automation())
                {
                    //2.获取主界面
                    var mainWindow = app.GetMainWindow(automation);
                    //窗口置顶显示  避免其它窗口遮挡影响后续操作
                    IntPtr handle = processes.First().MainWindowHandle;
                    SwitchToThisWindow(handle, true);    // 激活，显示在最
                    var childWind = mainWindow.FindChildAt(1).FindChildAt(0).FindChildAt(1).FindChildAt(0).FindChildAt(0).FindChildAt(0);
                    childWind.DrawHighlight(System.Drawing.Color.Red);
                    childWind.Click();
                    //搜索"文件传输助手"
                    Keyboard.Type("文件传输助手");
                    Thread.Sleep(800);
                    //回车
                    Keyboard.Type(VirtualKeyShort.RETURN);
                    Thread.Sleep(800);
                    //输入内容
                    Keyboard.Type("文件传输助手");
                    Thread.Sleep(800);
                    //回车
                    Keyboard.Type(VirtualKeyShort.RETURN);




                }
            }
        }

    }
}

三原理如下

查找pane 节点 1,0,1,0,0,0

找到搜索

mainWindow.FindChildAt(1).FindChildAt(0).FindChildAt(1).FindChildAt(0).FindChildAt(0).FindChildAt(0);
