我如何在c#中将字符串转换为日期时间#

string dateString = "2022-01-01";
string format = "yyyy-MM-dd";
DateTime dateTime = DateTime.ParseExact(dateString, format, CultureInfo.InvariantCulture);

string dateString = "2022-01-01";
string format = "yyyy-MM-dd";
DateTime dateTime;
if (DateTime.TryParseExact(dateString, format, CultureInfo.InvariantCulture, DateTimeStyles.None, out dateTime))
{
    Console.WriteLine("Converted dateTime: " + dateTime);
}
else
{
    Console.WriteLine("Unable to convert the string to DateTime.");
}
