C#UI自动化实现微信自动搜索聊天文件并发送

用到了两个程序包，FlaUI .Core,FlaUI.UIA3,在VS的扩展里可以下载安装这两个程序包，UI自动化是用来实现自动测试程序流程的，减少人工测试的成本。有需要源程序的私信我。

获取微信窗口句柄 

void GetWxHandle()
        {
            var process = Process.GetProcessesByName("Wechat").FirstOrDefault();
            if (process != null)
            {
                ProcessId = process.Id;
            }

        }

检测微信是否登录，并激活微信聊天窗 

bool InitWechat()
{
            //根据微信进程ID绑定FLAUI
            Application = FlaUI.Core.Application.Attach(ProcessId);
            if (Application.HasExited)
            {
                MessageBox.Show("请登录微信！");
                return false;
            }
            var automation = new UIA3Automation();
            var windows= Application.GetAllTopLevelWindows(automation);
            //获取微信window自动化操作对象
          
            if (windows.Count()== 0)
            {
                MessageBox.Show("请打开聊天窗口！");
                return false;  
            }
            else
            {
                wxWindow = Application.GetMainWindow(automation);
                if (wxWindow.AsWindow().Patterns.Window.PatternOrDefault != null)
                {
                    //将微信窗体设置为默认焦点状态
                    wxWindow.AsWindow().Patterns.Window.Pattern.SetWindowVisualState(FlaUI.Core.Definitions.WindowVisualState.Normal);
                }
                return true;
            }
         
 }

点击发送按钮，自动搜索聊天记录，并转发给最新发送的人 

  private async void  button1_Click(object sender, EventArgs e)
        {
            var path = textBox1.Text;
            var sendMsg = path.Substring(path.LastIndexOf("\\") + 1, path.Length-path.LastIndexOf("\\")-1);
            var itemName = sendMsg;
            if( !InitWechat())
            {
               return;
            }
                
            if (wxWindow != null)
