如何使用InnerElement将字符串转换为datetime

Question

我设法将值从字符串存储到日期时间格式，但它不起作用，你能帮助吗

public List<CaseListEntry> GetCaseListEntries()
    {
        var CaseGridTrs = CaseListGrid.FindElements(By.XPath(".//tr"));
        var entryList = CaseGridTrs.Select(x => 
        {
            var CaseEntryTds = x.FindElements(By.XPath(".//td"));
            return new CaseListEntry
            {

                Register = CaseEntryTds.ElementAt(0).FindElement(By.XPath(".//a")).Text,
                DateTime = CaseEntryTds.ElementAt(1).Text.----------?
