在asp.net c#中比较字符串格式的2个日期

string dateString1 = "2022-01-01";
string dateString2 = "2022-02-01";

DateTime date1 = DateTime.ParseExact(dateString1, "yyyy-MM-dd", CultureInfo.InvariantCulture);
DateTime date2 = DateTime.ParseExact(dateString2, "yyyy-MM-dd", CultureInfo.InvariantCulture);

int result = DateTime.Compare(date1, date2);

if (result < 0)
{
    Console.WriteLine("日期1早于日期2");
}
else if (result > 0)
{
    Console.WriteLine("日期1晚于日期2");
}
else
{
    Console.WriteLine("日期1等于日期2");
}
