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"));

How to set time to Zeros in DateTime?

Lets say I have the following DateTime variable
DateTime CurDate = '26/3/2014 12:00:00 AM';
I'm wondering how can I set the CurDate so that the value will become 26/3/2014 00:00:00 AM
Note that I still want the time, but with all zeros.
**P/S: The reason for having all zeros is because the datetime value stored in SQL Server is 26/3/2014 00:00:00.000. I need to cast CurDate to have all zeros in order to match database data

You can simply use
CurDate.Date and that will give you '26/3/2012 00:00:00'

Try to format DateTime:
DateTime dt = new DateTime(2014, 06, 21, 0, 0, 0);
Console.WriteLine(dt.ToString("dd.MM.yyyy HH:mm:ss tt"));
Result:
21.06.2014 00:00:00
More informations:
http://msdn.microsoft.com/en-us/library/8kb3ddd4(v=vs.110).aspx

You could try this one:
// Parse the string you have, to create a datetime.
DateTime CurDate = DateTime.ParseExact('26/3/2014 12:00:00 AM',
"dd-MM-yyyy HH:mm:ss",
CultureInfo.InvariantCulture);
// Create the datetime you want based on the CurDate
DateTime result = new DateTime(CurDate.Year, CurDate.Month, CurDate.Day, 0, 0, 0);
For more information about ParseExact please have a look here.

Nowhere, in SQL Server or in .NET dates hasn't any presentation. They are just an numeric value. Don't care about that, both the SQL Server and .NET so smart that can pass parameters without any confusion. Just pass parameters of the correct data type.

Use 24 Hour Format
DateTime CurDate = DateTime.Parse("3/26/2014 12:00:00 AM");
Console.WriteLine("12 Hour Format: " + CurDate.ToString("dd-MM-yyyy hh:mm:ss"));
Console.WriteLine("24 Hour Format: " + CurDate.ToString("dd-MM-yyyy HH:mm:ss"));

I know it's late but I think this was the proper answer for future references:
Console.WriteLine("Current Date with 0s on time part: " + DateTime.Now.ToString("yyyy-MM-dd 00:00:00.000"));

this.dtGelisSaati = DateTime.Now;
set curency time values
this.dtGelisSaati = DateTime.Today;
this ok. zero time values set.

Put .Date and get the date part with zero time part.
I use Linq as:
var list = Results.Where(x => x.ExpDate.Date >= From.Date && x.ExpDate.Date <= To.Date).ToList();

Merge today's date with a timespan data type value

I'm trying to merge today's date with an existing time value I have stored in a sql server database. Let me give you an example:
ClientTradedTime = "16:52:01" (this is of type timespan)
I want to merge that value with today's date in variable of type DateTime to use it else where, example:
DateTime mydate;
mydate = "2014-02-04 16:52:01" (this is what I want to see when I store it in my database)
How can I solve this problem?

Just Datime.Add() the TimeSpan to the DateTime's Date property and you will get your desired DateTime like:
DateTime updatedDt = mydate.Date.Add(ClientTradedTime);
Consider the following example:
DateTime myDate = DateTime.Now;
TimeSpan ClientTradedTime = new TimeSpan(16, 52, 51);
DateTime updatedDt = myDate.Date.Add(ClientTradedTime);
This will give you:
updatedDt = {04/02/2014 4:52:51 PM}
myDate.Date would give you DateTime with Time set to 00:00:00 and then you can add your TimeSpan to it.

today() function returns date with time when project converted to .net

My application behaves differently when I work on Windows Server 2008 R2.
When I converted my PowerScript to .net project, today() 's functions returns the value as date along with time (date+time) instead of only date.
ldt_date = today()
any suggestions?

you can add ToString formatting
yourdate.ToString("d");

That is normal .NET behavior.
DateTime dt = DateTime.Today;
Console.WriteLine(dt.ToString); //output 6/23/2012 12:00:00 AM
if you want date only (6/23/2012) try:
DateTime dt = DateTime.Today;
Console.WriteLine(dt.ToShortDateString()); //output 6/23/2012

In .NET you can get the only date part of DateTime variable using DateTime.Date Property
It's like
yourdate.ToString("d")
Example
DateTime date1 = new DateTime(2008, 6, 1, 7, 47, 0);
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("d"));

Assign datetime value to today's date with specific time

I have a variable which is defined as a DateTime. I need to assign it today's date but have the time be 4 PM. How do I do this?

You want DateTime.Today.AddHours(16)
DateTime.Today will return today's date at midnight.
You can also use the Date property to drop the time from an arbitrary DateTime value.

I think this should do what you need...
DateTime today = DateTime.Today;
DateTime dt = new DateTime(today.Year, today.Month, today.Day, 16, 0, 0);

var anotherTime = DateTime.Today.AddHours(16.0);

Take a look at all the overloaded constructors for DateTime.
DateTime myDate = new DateTime(DateTime.Today.Year, DateTime.Today.Month, DateTime.Today.Day, 16, 0, 0);
Edit: Correction. Thanks Jon. :)
