DateTime.Parse抛出字符串无法识别，我看不到为什么

Question

I cannot understand why this is throwing "String was not recognized as a valid DateTime"

        string[] formats = {"M/d/yyyy h:mm:ss tt", "M/d/yyyy h:mm tt",
               "MM/dd/yyyy hh:mm:ss", "M/d/yyyy h:mm:ss",
               "M/d/yyyy hh:mm tt", "M/d/yyyy hh tt",
               "M/d/yyyy h:mm", "M/d/yyyy h:mm", "MM/dd/yyyy hh:mm",
               "MM/dd/yyyy hh:mm", "M/dd/yyyy hh:mm",
               "MM/d/yyyy HH:mm:ss.ffffff" };
    var delimit = line.Split(',');
    try
    {
        id = delimit[0];
        DateTime.TryParseExact(delimit[1].Trim(),formats,new CultureInfo("en-US"),DateTimeStyles.None, out openDate);
        delimit[5] = delimit[5].Replace("\"","");
        closedDate = DateTime.ParseExact(delimit[5].Trim(),formats,new CultureInfo("en-US"),DateTimeStyles.None);
        DateTime.TryParseExact(delimit[5].Trim(),formats,new CultureInfo("en-US"),DateTimeStyles.None, out closedDate);
        severity = delimit[7].Split('-').Last().Trim();
        state = delimit[6].Trim();
    }
    catch(Exception e)
    {

        Console.WriteLine(line);
    }

The entry it throws on is :

The formats array should include the 24 hour time format.

Either dd/MM/yyyy HH:mm OR MM/dd/yyyy HH:mm OR M/d/yyyy HH:mm OR d/M/yyyy H:m format can be used.

Please note that only you know whether your format is dd-MM-yyyy or MM-dd-yyyy as for both date and month places you have 12.

You can check the sample inputs to your code and depending on those you should choose the format carefully.

Hope this helps.
