在努力解决DateTime.ParseExact格式化问题时,我决定从DateTime.ToString()向ParseExact提供输出,如下所示:

DateTime date2 = new DateTime(1962, 1, 27);
string[] expectedFormats = { "G", "g", "f", "F", "D", "d", "M/d/yyy", "MM/dd/yyy", "MM-dd-yyy", "MMM dd, yyy", "MMM dd yyy", "MMMM dd, yyy", "MMMM dd yyy" };
bool parsed = false;

foreach (string fmt in expectedFormats)
{
    try
    {
        DateTime dtDateTime = DateTime.ParseExact(date2.ToString(fmt), fmt, new CultureInfo("en-US"));
        parsed = true;
    }
    catch (Exception)
    {
        parsed = false;
    }

    Console.WriteLine("[{0}] {1}", parsed,date2.ToString(fmt));
}

这是输出:

[True] 1/27/1962 12:00:00 AM
[True] 1/27/1962 12:00 AM
[True] Saturday, January …
