How to extract YYYY-mm-dd from date string?

I have date in format 2017-08-24 22:22:45. How to extract only 2017-08-24?
I tried to use:
var data = date.Split('-');
string convertedDate = data[0] + date[1] + date[2];
But I dislike this solution/

DateTime s = DateTime.Parse("2017-08-24 22:22:45");
Console.WriteLine(s.ToString("yyyy-MM-dd"));

Other option could be:
string date = "2017-08-24 22:22:45";
string convertedDate = date.Split(' ')[0];
// Result: 2017-08-24

if Date:
string convertedDate = date.ToString("yyyy-MM-dd");
if String:
string convertedDate = data.Substring(0,10);

Simply:
var convertedDate = date.Substring(0, 10);

Your string can be converted into a DateTime object then you can use however you want.
string dateStr = "2017-08-24 22:22:45";
DateTime date = DateTime.Now;
if(DateTime.TryParse(dateStr, out date))
Console.Write(date.ToString("yyyy-MM-dd"));

Using ParseExact
var strDate = "2017-08-24 22:22:45";
DateTime myDate = DateTime.ParseExact(strDate, "yyyy-MM-dd HH:mm:ss",
System.Globalization.CultureInfo.InvariantCulture);
Console.WriteLine("Your date "+ myDate.ToString("yyyy-MM-dd"));

You could use a Regular Expression pattern:
var src = "2017-08-24 22:22:45";
var pattern = #"^\d{4}-\d{2}-\d{2}";
var ans = Regex.Match(src, pattern).Value;
But that is probably overkill - just extract it:
var ans = src.Substring(0, 10);

This works for you,
string date = "2017-08-24 22:22:45";
string convertedDate = date.Split(' ')[0];

Trim a string to get date in middle? [duplicate]

I need the following string trimmed
Sat, 02/04/1708:00 PM
so that the result is 02/04/17
How can I accomplish this?

you can use Split() and Substring()
var str = #"Sat, 02/04/1708:00 PM";
var res = str.Split(' ')[1].Substring(0, 8);

Regex rg = new Regex(#"[01]?\d[/-][0123]?\d[/-]\d{2}");
Match m = rg.Match("Sat, 02/04/1708:00 PM");
Console.Write(m.ToString());
WORKING FIDDLE

you can use substring
string str="Sat, 02/04/1708:00 PM";
string newStr=str.Substring(5,8);

You can also do this:
string strInput = #"Sat, 02/04/1708:00 PM";
var dateResult = strInput.Split(' ', ',')[2];

This might do the trick for you.
string smdt = "Sun, 02/04/1708:00 PM";
string format = "ddd, dd/MM/yyhh:mm tt";
DateTime dt = DateTime.ParseExact(smdt, format, CultureInfo.InvariantCulture, DateTimeStyles.None);
string extractedDate = dt.ToString("dd/MM/yy");
The problem with the Question was the Date 02/04/17 is not a Saturday instead it will be Sunday and thus it will not be able to convert to a DateTime. When I change Sat to Sun. The extractedDate is the result which you are looking for.
One liner answer could be
string smdt = "Sun, 02/04/1708:00 PM";
string extractedDate = DateTime.ParseExact(
smdt,
"ddd, dd/MM/yyhh:mm tt",
CultureInfo.InvariantCulture,
DateTimeStyles.None
).ToString("dd/MM/yy");

String str = #"Sat, 02/04/1708:00 PM";
String expected = str.split(' ')[1].Substring(0,8);

How to convert a string of MM-dd-yyyy to (full month)-yyyy

I have a string variable with the value of 07/31/2016 and I need to convert this to show as July 2016. How can I do this in C#?

var input = "07/31/2016";
var date = DateTime.Parse(input);
var output = date.ToString("MMMM-yyyy");
See DateTime.Parse.
See also date and time format strings.

CultureInfo provider = CultureInfo.InvariantCulture;
var input = "07/31/2016";
var date = DateTime.ParseExact(input,"MM/dd/yyyy",provider);
var output = date.ToString("MMMM-yyyy");

This should be work:
string iDate = "07/31/2016";
DateTime oDate = Convert.ToDateTime(iDate);
Console.WriteLine(CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(oDate.Month) + " " + oDate.Year);

Parse to DateTime and call ToString() with the new format.

Convert ShortTime string to DateTime format

DateTime time = DateTime.Now;
string newTime = time.ToShortTime();
How to convert this newTime string into DateTime format

Please try with the below code snippet.
DateTime time = DateTime.Now;
string newTime = time.ToShortTimeString();
DateTime dt = new DateTime();
DateTime.TryParse(newTime,out dt);
Note : It will set current Date.

Finaly I found an answer
const string FMT = "O";
DateTime now1 = DateTime.Now;
string strDate = now1.ToString(FMT);
DateTime now2 = DateTime.ParseExact(strDate, FMT, CultureInfo.InvariantCulture);

DateTime ParseExact exception

var str = "00:00:00 02/01/1990";
var dt = DateTime.ParseExact(str, "hh:mm:ss dd/MM/yyyy", null);
The above code is throwing an exception "String was not recognized as a valid DateTime."
I thought using ParseExact and specifying the exact format this would be okay. What is wrong with the above?
EDIT:
Solved using invariant culture. Thanks for comments.
var dt = DateTime.ParseExact(str, "HH:mm:ss dd/MM/yyyy", CultureInfo.InvariantCulture);

The "hh" format specifier is for 12-hour AM/PM time, which doesn't support a "00". Try defining it in 24-hour time: HH:mm:ss dd/MM/yyyy

Yes usually in DateTime format the Date comes first before Time. Try this out:
var str = "02/01/1990 00:00:00";
var dt = DateTime.ParseExact(str, "hh:mm:ss dd/MM/yyyy", null);
EDITED: OK so you do one trick to get it done:
var str = "00:00:00 02/01/1990";
var split = str.Split(new char[] { ' ' });
if (split.Length == 2)
str = String.Format("{0} {1}", split[1], split[0]);
var dt = DateTime.ParseExact(str, "hh:mm:ss dd/MM/yyyy", null);
