Hello,
I am declaring a date and then passing it to an input box. I'm trying to only show the date without the time but I can't seem to get rid of the time component. Also, once I've solved this, will I be able to save the data as date only, or will having the field type as "datetime" end up with the computer adding midnight seconds?

Calling method:

C#

DateTime value = DateTime.Now.Date;
if (InputBoxes.InputBoxDate("Enter invoice date", "Enter the date for this invoice.", ref value) == DialogResult.OK)

Receiving method with all other info removed

public static DialogResult InputBoxDate(string title, string promptText, ref DateTime value)

textBox.Text = value.Date.ToString();
value = Convert.ToDateTime(textBox.Text);
return dialogResult;

I think there is no Date only data type in C#. Hence, even if only Date is required the DateTime Type of C# is to be used, which stores both the Date and Time.

However, the the DateTime in UI controls and reports can be represented as a string in the required format using either the Custom Date and Time Format Strings[^] or using Standard Date and Time Format Strings[^]

The DateTime format is influenced by the CurrentCulture if a specific culture is not given while parsing from a string and while converting to the string format.

So, if a Culture independent conversion is required then InvariantCulture can be used as follows.

C#

DateTime today = DateTime.Now;
	
string todayAsText = today.ToString("dd/MM/yyyy",
							System.Globalization.CultureInfo.InvariantCulture);
Console.WriteLine (todayAsText);

DateTime parsedDate = DateTime.ParseExact("14/06/2012","d/M/yyyy",
							System.Globalization.CultureInfo.InvariantCulture);
//Note: d, M in the above format reads single and double digit
//date and month like 05, 5  whereas dd, MM reads only 05
Console.WriteLine (parsedDate.ToString());

/*
Output
14/06/2012
6/14/2012 12:00 
*/

So, in the above example, the code

C#

textBox.Text = value.Date.ToString();
value = Convert.ToDateTime(textBox.Text);

can be modified using DateTimeFormat as shown in the above example to achieve the effect of only Date
