C# - Parse Date and Time Strings in .NET

DateTime oDate00 = Convert.ToDateTime("5/29/2020 8:02:41 AM",

CultureInfo.InvariantCulture);

DateTime oDate000 = Convert.ToDateTime("09/05/2020 8:02:41 AM",

CultureInfo.InvariantCulture);

DateTime oDate0000 = Convert.ToDateTime("9/5/2020 8:02:41 AM",

CultureInfo.InvariantCulture);

DateTime oDate00000 = Convert.ToDateTime("5/9/2020 8:02:41 AM",

CultureInfo.InvariantCulture);

DateTime oDate000000 = DateTime.ParseExact("28/05/2020 12:53:55 PM",

"dd/M/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture);

DateTime oDate0000000 = DateTime.ParseExact("25/12/2017 4:00 PM",

"dd/MM/yyyy h:mm tt", CultureInfo.InvariantCulture);

Example

string dateInput = "Jan 1, 2009";

var parsedDate = DateTime.Parse(dateInput);

Console.WriteLine(parsedDate);

// Displays the following output on a system whose culture is en-US:

//       1/1/2009 00:00:00

var cultureInfo = new CultureInfo("de-DE");

string dateString = "12 Juni 2008";

var dateTime = DateTime.Parse(dateString, cultureInfo);

Console.WriteLine(dateTime);

// The example displays the following output:

//       6/12/2008 00:00:00

var cultureInfo = new CultureInfo("de-DE");

string dateString = "12 Juni 2008";

var dateTime = DateTime.Parse(dateString, cultureInfo,

                                DateTimeStyles.NoCurrentDateDefault);

Console.WriteLine(dateTime);

// The example displays the following output if the current culture is en-US:

//      6/12/2008 00:00:00

ParseExact

var cultureInfo = new CultureInfo("en-US");

string[] dateStrings = { " Friday, April 10, 2009", "Friday, April 10, 2009" };

foreach (string dateString in dateStrings)

{

    try

    {

        var dateTime = DateTime.ParseExact(dateString, "D", cultureInfo);

        Console.WriteLine(dateTime);

    }

    catch (FormatException)

    {

        Console.WriteLine("Unable to parse '{0}'", dateString);

    }

}

// The example displays the following output:

//       Unable to parse ' Friday, April 10, 2009'

//       4/10/2009 00:00:00
