In C#, the DateTime type represents date and time values. Formatting DateTime values allows you to customize the representation of dates and times according to your specific requirements. In this article, we’ll explore the DateTime format options available in C# and how to utilize them to format date and time values.

DateTime Formatting Options

C# provides a variety of formatting options for DateTime values. These formatting options are represented by standard format strings and custom format strings.

Standard Format Strings for DateTime

Standard format strings in C# provide predefined formatting options for DateTime values. These format strings are represented by a single character or a combination of characters that specify the desired format.

Here’s an example that demonstrates the usage of a standard format string:

DateTime now = DateTime.Now;
string shortDate = now.ToString("d");
Console.WriteLine($"Short Date: {shortDate}");
string longDateTime = now.ToString("F");
Console.WriteLine($"Long Date and Time: {longDateTime}");

In this example, the “d” format specifier represents the short date format, and the “F” format specifier represents the long date and time format.

Custom Format Strings For DateTime

Custom format strings in C# allow you to define a custom pattern for formatting DateTime values. By combining various placeholders and format specifiers, you can create a format that meets your specific requirements.

Here’s an example that demonstrates the usage of a custom format string:

DateTime now = DateTime.Now;
string customFormat = now.ToString("MMMM d, yyyy hh:mm:ss tt");
Console.WriteLine($"Custom Format: {customFormat}");

In this example, the custom format string “MMMM d, yyyy hh:mm:ss tt” represents the format of the date and time as “Month Day, Year Hour:Minute:Second AM/PM”.
