C# || How To Get The Date Value & Time Value From A Date Using C#

May 23, 2021 admin No comments

The following is a module with functions which demonstrates how to get the date value and time value from a DateTime using C#.

The functions listed on this page demonstrates how to isolate the date portion of a date, as well as the time portion of a date. For example, given the date “5/23/2019 7:28:31 PM”, the date value would be 5/23/2019, and time value 7:28:31 PM.

1. Date Value

The example below demonstrates the use of ‘Utils.Methods.DateValue‘ to get the date value of a date.

The DateTime object value contains the date information, with the time portion set to midnight (00:00:00)





		
		
			1. Date Value
			
C#
			
			// Date Value

// Declare date value
var original = "5/23/2019 7:28:31 PM";

// Get the date portion
var dateOnly = Utils.Methods.DateValue(original);

// Display results
Console.WriteLine($@"
    Original: {original}
    Date Value: {dateOnly}
");

// example output:
/*
    Original: 5/23/2019 7:28:31 PM
    Date Value: 5/23/2019 12:00:00 AM
*/

// Declare date value
var original = "5/23/2019 7:28:31 PM";
 
// Get the date portion
var dateOnly = Utils.Methods.DateValue(original);
 
// Display results
Console.WriteLine($@"
    Original: {original}
    Date Value: {dateOnly}
");
 
// example output:
/*
    Original: 5/23/2019 7:28:31 PM
    Date Value: 5/23/2019 12:00:00 AM
*/

2. Time Value

The example below demonstrates the use of ‘Utils.Methods.TimeValue‘ to get the date value of a date.

The DateTime object contains the time information, with the date portion set to January 1 of the year 1





		
		
			2. Time Value
			
C#
			
			// Time Value

// Declare date value
var original = "5/23/2019 7:28:31 PM";

// Get the time portion
var timeOnly = Utils.Methods.TimeValue(original);

// Display results
Console.WriteLine($@"
    Original: {original}
    Time Value: {timeOnly}
");

// example output:
/*
    Original: 5/23/2019 7:28:31 PM
    Time Value: 1/1/0001 7:28:31 PM
*/

// Display results
Console.WriteLine($@"
    Original: {original}
    Time Value: {timeOnly}
");
 
// example output:
/*
    Original: 5/23/2019 7:28:31 PM
    Time Value: 1/1/0001 7:28:31 PM
*/

3. Utils Namespace

The following is the Utils Namespace. Include this in your project to start using!
