I need only date value part and time value part using ASP.NET C#

I have two parameters one for date and another for time, and i need date value part and time values part.
My two parameters are below.
// For Date parameter
DateTime dt = DateTime.ParseExact("01-jan-1999", "dd-MMM-yyyy", CultureInfo.InvariantCulture);
bo.Dateused5 = dt;
// For Time parameter
string Fromtiming = ddl_FromHours.SelectedItem.ToString() + ":" + ddl_FromMinutes.SelectedItem.ToString();
DateTime InterviewTime = Convert.ToDateTime(Fromtiming);//StartTime
bo.Dateused4 = InterviewTime;//InterviewTime
so i need to send mail to the candidate to only date part, should not contain time and time part, should not contain date.

are you looking for this:
DateTime dt = DateTime.ParseExact("01-jan-1999", "dd-MMM-yyyy", CultureInfo.InvariantCulture);
string mailDate = dt.ToString("dd-MMM-yyyy");// will give 01-jan-1999
string date = dt.ToString("dd-MM-yyyy"); // will give 01-01-1999
You can also try using String.Format()
string mailDate = String.Format("{0:dd-MM-yyyy}", dt); // will give 01-01-1999

You can use ToShortDateString():
DateTime dt = DateTime.ParseExact("01-jan-1999", "dd-MMM-yyyy", CultureInfo.InvariantCulture);
var date = dt.ToShortDateString();
Note that it uses date format attached to the current thread's culture info.

You would need to use strings rather than dates, so change the type of your variables to string so that
bo.Dateused5 = dt.ToString("dd-MMM-yyyy")
would set Dateused5 to a string of the date component, then
bo.Dateused4 = InterviewTime.ToString("HH:MM");
would set Dateused4 to the time component.

Couldn't test your code but I am very sure there are Functions "DateValue" and "TimeValue" you can make use of.
Something like,
Format(DateValue(any datetime), "dd-MM-yyyy")
gives you Only Date in the specified format. Similar way for TimeValue

DateTime.Parse Not Parsing

I'm trying to return the date as "2015-06-18"
string strDate = DateTime.Now.ToString("yyyy-MM-dd");
DateTime newDate = DateTime.Parse(strDate);
This returns "2015/06/18 hh:mm:ss"
What am I missing?

If you want a particular output format, you can specify one yourself.
string strDate = DateTime.Now.ToString("yyyy-MM-dd");
DateTime newDate = DateTime.Parse(strDate);
string output = newDate.ToString("yyyy-MM-dd");
Console.WriteLine (output); // produces 2015-06-18 right now
The DateTime structure in .net always includes the time of day, and there is no built-in way to store only a date, so if you want to exclude it, you'll need to use the formatting options.

What you need is to format the datetime object.
newDate.ToString("yyyy-MM-dd") -> 2015-06-19

Why don't you just use the DateTime.Date property?
DateTime date1 = DateTime.Now;
Console.WriteLine(date1.ToString());
// Get date-only portion of date, without its time.
DateTime dateOnly = date1.Date;
// Display date using short date string.
Console.WriteLine(dateOnly.ToString("yyyy-MM-dd"));

MVC 4 - Force DateTime

Is it possible to force a DateTime object to use a different locale? I wish to populate a DateTime object with a UK DateTime but formatted as US.
I have tried the following:
DateTime ukDateTimeFormat = DateTime.Parse("10/26/2009 06:47", CultureInfo.GetCultureInfo("en-us"));
DateTime usDateTimeFormat = DateTime.Parse("26/10/2009 06:47", CultureInfo.GetCultureInfo("en-gb"));
string strDate = DateTime.Now.ToString(CultureInfo.InvariantCulture);
string[] dateString = strDate.Split('/');
DateTime enterDate = DateTime.Parse(dateString[0] + "/" + dateString[1] + "/" + dateString[2], CultureInfo.GetCultureInfo("en-us"));
Nothing works, I always end up with a UK formatted date.
Any help would be much appreciated :-)

It seems like you're confused between representing a date-time and formatting a date-time.
DateTime does not contain any format, it only represents the actual time. So the question about a US/UK format of a DateTime is meaningless.
If you want to display the time in a different format, that's not a DateTime, that's a string. You can use the various overloads of DateTime.ToString(...) in order to achieve different formatting as a string. There are some built-in formats, and you can specify a locale.

The DateTime object does not have an internal string format as such - your date is stored as a date and formatted on output. You can populate however you wish, however when outputting it, you'll need to specify your format, e.g.:
string formattedDate = ukDateFormat.ToString("MM/dd/yyyy HH:mm");

To format your date for the locale, use this code:
string formattedDate = ukDateFormat.ToString(System.Globalization.CultureInfo.CreateSpecificCulture("en-us"))

Join date and time in c#

I have a win form c# SQL app that stores date in one column and time in the another.
There is only one date time picker on my form and I want to display both date and time values (which are from two separate columns)..
So far this is what I've done
Datetime final = datetime. Parse exact (date + " " + time , "MM/dd/yyyy hh:mm tt", cultureinfo. Invariant culture);
But it throws " string was not recognized as valid datetime" exception on the above line.

If date and time are DateTime variables, you can combine them with date arithmetic:
DateTime date=...;
DateTime time = ...;
DateTime finalDate = date.Date + time.TimeOfDay;
If they are strings, you can parse them to DateTime and TimeSpan variables:
DateTime date=DateTime.ParseExact(dateString,dateFormat,CultureInfo.InvariantCulture);
TimeSpan time = TimeSpan.ParseExact(timeString,timeFormat,CultureInfo.InvariantCulture);
DateTime finalDate = date.Date + time;
This is possible because you can add a DateTime and a TimeSpan value to get a new DateTime value

You can use TimeSpan.Parse to parse
DateTime newDateTime = date.Add(TimeSpan.Parse(time));

string d = DateTime.Now.Date.ToString("dd/MM/yyyy");
string t = DateTime.Now.ToString("h:mm");
var ts = TimeSpan.ParseExact(t, #"h\:mm",CultureInfo.InvariantCulture);
DateTime result = DateTime.ParseExact(d, "dd/MM/yyyy", CultureInfo.InvariantCulture)+ts;
Hope this helps,
Thanks.

Save two TextBox as DateTime asp.net C#

I have two textBox in first i have Date in this format : 2012.09.20 and in the second i have Time in this format: 15:30:00. In database i have Column name "Eventstart" type: DateTime. Now i like to take the value from two textbox and put them in something like this:
DateTime end = Convert.ToDateTime(TextBoxEnd.Text) + Convert.ToDateTime(TextBoxTimeEnd.Text);
But give me this error : Error 2 Operator '+' cannot be applied to operands of type 'System.DateTime' and 'System.DateTime'

It sounds like you should be using:
DateTime date = Convert.ToDateTime(TextBoxEnd.Text);
DateTime time = Convert.ToDateTime(TextBoxTimeEnd.Text);
DateTime combined = date.Date + time.TimeOfDay;
Or you could combine the text and then parse that:
DateTime dateTime = Convert.ToDateTime(TextBoxEnd.Text + " " +
TextBoxTimeEnd.Text);
I'm not sure I'd use Convert.ToDateTime at all though - if you know the exact format that the textbox will be in, you should use DateTime.TryParseExact. You should work out which culture to use in that case though. If it's a genuinely fixed precise format, CultureInfo.InvariantCulture might be appropriate. If it's a culture-specific format, then use the user's culture.
You might also want to use an alternative UI representation which doesn't use textboxes at all, which would avoid potentially troubling string conversions.

Concatenate your TextBoxes text and use DateTime.ParseExact with format "yyyy.MM.dd HH:mm:ss"
After concatenating the text you should have: "2012.09.20 15:30:00"
DateTime dt = DateTime.ParseExact(TextBoxEnd.Text + " " + TextBoxTimeEnd.Text,
"yyyy.MM.dd HH:mm:ss",
CultureInfo.InvariantCulture);

Have you tried something like
DateTime end = Convert.ToDateTime(TextBoxEnd.Text) + TimeSpan.Parse(TextBoxTimeEnd.Text);

First concatenate both the values and then add it to a DateTime variable
example:
string str = date.Text + time.Text; // assumed date and time are textboxes
DateTime dt=new DateTime();
DateTime.TryParse(str,dt); // returns datetime in dt if it is valid
