日期时间选择器不保存日期

如何解决日期时间选择器不保存日期

我有设置日期时间选择器的自动化测试，日期正在更改但未保存 你可以在这里看到代码：

            DateTime dateTime = new DateTime(year,month + 1,day);
            DateTime today = DateTime.Now;
            string monthDate = dateTime.ToString("MMMM");
            string dayDate = dateTime.ToString("%d");
            string yearDate = dateTime.ToString("yyyy");
            TimeSpan timeout = TimeSpan.FromSeconds(30);

            _app.WaitForElement(x => x.Class("UIDatePicker"),timeout: timeout);
            if (today.Month < month + 1)
            {
                _app.ScrollDownTo(z => z.Marked(monthDate),x => x.Class("UIDatePicker").Index(0),timeout: timeout,strategy: ScrollStrategy.Auto);
            }
            else
            {
                _app.ScrollUpTo(z => z.Marked(monthDate),strategy: ScrollStrategy.Auto);
            }

            _app.Tap(x => x.Text(monthDate));

            _app.Query(x => x.Class("UIPickerView").Invoke("selectRow",1,"inComponent","animated",true));
            if (today.Day < day)
            {
                _app.ScrollDownTo(z => z.Marked(dayDate),x => x.Class("UIDatePicker").Index(1),strategy: ScrollStrategy.Programmatically);
            }
            else
            {
                _app.ScrollUpTo(z => z.Marked(dayDate),strategy: ScrollStrategy.Programmatically);
            }

            _app.Tap(x => x.Text(dayDate)); 

            _app.ScrollUpTo(z => z.Marked(yearDate),x => x.Class("UIDatePicker").Index(2),strategy: ScrollStrategy.Programmatically);
            _app.Tap(x => x.Text(yearDate));

            _app.Tap("Done");

当我尝试为 02/02/2020 设置日期时的示例：

在我点击“完成”后：

我得到的是今天的日期，但年份是 2020 年
