            Console.WriteLine("Converted '{0}' to {1}.", string_date, dateValue);
        else
            Console.WriteLine("Unable to convert '{0}' to a date.", string_date);
        return dateValue;

    {
        string inString = "05/01/2009 06:32:00";
        GetDate(inString);
    }
}
}

/**
 * Output:
 * Converted '05/01/2009 06:32:00' to 5/1/2009 6:32:00 AM.
 * */

将一个人类可读的字符串的值放入.NET DateTime中，代码如下:

DateTime.ParseExact("April 16, 2011 4:27 pm", "MMMM d, yyyy h:mm tt", null);

还可以使用XmlConvert。ToDateString

var dateStr = "2011-03-21 13:26";
var parsedDate = XmlConvert.ToDateTime(dateStr, "yyyy-MM-dd hh:mm");

最好指定日期类型，代码为:

var anotherParsedDate = DateTime.ParseExact(dateStr, "yyyy-MM-dd hh:mm", CultureInfo.InvariantCulture, DateTimeStyles.AssumeUniversal);

关于不同解析选项的更多详细信息http://amir-shenodua.blogspot.ie/2017/06/datetime-parsing-in-net.html

DateTime。DateTime, Format, DateTimeFormatInfo。InvariantInfo DateTimeStyles。allowtrailingwhite)

例如:

DateTime。ParseExact("2011-03-21 13:26"， "yyyy-MM-dd hh:mm"， DateTimeFormatInfo. "InvariantInfo DateTimeStyles。AllowLeadingWhite | DateTimeStyles.AllowTrailingWhite;

DateTime.Parse()应该适用于该字符串格式。参考:

它是否为你抛出FormatException ?
