Implement Basic Date and Time Operations

Date and time manipulation is a fundamental concept in software development that allows you to handle various operations related to scheduling events, logging transactions, session expiration, order processing, and data updates. In this exercise, you will create and manipulate date and time values in a C# console application. You will explore using DateTime, DateOnly, TimeOnly, and TimeZoneInfo classes to perform various date and time operations. Additionally, you will calculate date and time values for bank customer transactions and use date ranges to simulate transactions programmatically.

This exercise takes approximately 30 minutes to complete.

Before you start

Before you can start this exercise, you need to:

  1. Ensure that you have the latest short term support (STS) version of the .NET SDK installed on your computer. You can download the latest versions of the .NET SDK using the following URL: Download .NET

  2. Ensure that you have Visual Studio Code installed on your computer. You can download Visual Studio Code using the following URL: Download Visual Studio Code

  3. Ensure that you have the C# Dev Kit configured in Visual Studio Code.

For additional help configuring the Visual Studio Code environment, see Install and configure Visual Studio Code for C# development

Exercise scenario

Suppose you’re a software developer at a tech company working on a new project. Your team needs to implement basic date and time operations in a C# console application. To ensure consistent behavior, you decide to create and implement these operations in a simple console application.

You’ve developed an initial version of the app that includes the following files:

  • Program.cs: This file contains the main entry point of the application, demonstrating the creation and manipulation of date and time values.
  • Transaction.cs: This file defines the Transaction class, which includes properties for transaction details such as account ID, amount, description, and date.
  • BankAccount.cs: This file defines the BankAccount class, which includes properties and methods for managing bank account transactions.
  • SimulateTransactions.cs: This file contains methods for generating and simulating transactions over a specified date range.

This exercise includes the following tasks:

  1. Review the current version of your project.
  2. Create and manipulate date and time values.
  3. Construct date and time values for bank customer transactions.
  4. Use date ranges to simulate transactions programmatically.

Review the current version of your project

In this task, you download the existing version of your project and review the code.

Use the following steps to complete this section of the exercise:

  1. Download the starter code from the following URL: Implement collection types - exercise code projects

  2. Extract the contents of the LP4SampleApps.zip file to a folder location on your computer.

  3. Expand the LP4SampleApps folder, and then open the Data_M1 folder.

    The Data_M1 folder contains the following code project folders:

    • Solution
    • Starter

    The Starter folder contains the starter project files for this exercise.

  4. Use Visual Studio Code to open the Starter folder.

  5. In the EXPLORER view, collapse the STARTER folder, select SOLUTION EXPLORER, and expand the Data_M1 project.

    You should see the following project structure:

    • Interfaces (folder)
    • Models (folder)
    • Services (folder)
    • Program.cs

  6. Take a few minutes to open and review the Program.cs file.

    • Program.cs: This file contains the main entry point of the application, demonstrating the creation and manipulation of date and time values.

  7. Run the app and review the output in the terminal window.

    You should see output that’s similar to the following sample:

     Demonstrate date and time operations:

    To run your app from the EXPLORER view, expand SOLUTION EXPLORER, right-click the Data_M1 project, select Debug, and then select Start New Instance.

    TIP: If you encounter any issues while completing this exercise, review the provided code snippets and compare them to your own code. Pay close attention to the syntax and structure of the code. If you’re still having trouble, you can review the solution code in the sample apps that you downloaded at the beginning of this exercise. To view the Data_M1 solution, navigate to the LP4SampleApps/Data_M1/Solution folder and open the Solution project in Visual Studio Code.

Create and manipulate date and time values

In this task, you will use the DateTime, DateOnly, TimeOnly, and TimeZoneInfo classes to create and manipulate date and time values.

  1. Ensure that you have the Program.cs file open in Visual Studio Code.

  2. Locate the following code comment:

     // TASK 1: Step 1 - Get the current date and time, and extract date and time components

  3. To get and display the current date and time, add the following code below the comment:

    DateTime currentDateTime = DateTime.Now;
Console.WriteLine($"Current Date and Time: {currentDateTime}");

  4. Locate the following code comment:

     // TASK 1: Step 2 - Get the current day of the week and the current month and year

  5. To get and display the date only, add the following code below the comment:

    DateOnly currentDate = DateOnly.FromDateTime(DateTime.Now);
Console.WriteLine($"Current Date: {currentDate}");

  6. To get and display the current time only, add the following code:

    TimeOnly currentTime = TimeOnly.FromDateTime(DateTime.Now);
Console.WriteLine($"Current Time: {currentTime}");

  7. To get and display the current day of the week, add the following code:

    DayOfWeek currentDayOfWeek = DateTime.Now.DayOfWeek;
Console.WriteLine($"Current Day of the Week: {currentDayOfWeek}");

  8. To get and display the current month and year, add the following code:

    int currentMonth = DateTime.Now.Month;
int currentYear = DateTime.Now.Year;
Console.WriteLine($"Current Month: {currentMonth}, Current Year: {currentYear}");

  9. Locate the following code comment:

     // TASK 1: Step 3 - Add days to the current date and parse a date string

  10. To add 10 days to the current date and display the result, add the following code below the comment:

    DateTime datePlusDays = DateTime.Now.AddDays(10);
Console.WriteLine($"Date Plus 10 Days: {datePlusDays}");

  11. To parse a date string and display the result, add the following code:

    DateTime parsedDate = DateTime.Parse("2025-03-13");
Console.WriteLine($"Parsed Date: {parsedDate}");

  12. Locate the following code comment:

     // TASK 1: Step 4 - Format a date and get the current timezone offset

  13. To format a date using the .ToString() method and “yyyy-MM-dd” format, add the following code below the comment:

    string formattedDate = DateTime.Now.ToString("yyyy-MM-dd");
Console.WriteLine($"Formatted Date: {formattedDate}");

  14. To get the current timezone and offset from UTC, add the following code:

    TimeZoneInfo currentTimeZone = TimeZoneInfo.Local;
TimeSpan offsetFromUtc = currentTimeZone.GetUtcOffset(DateTime.Now);
Console.WriteLine($"Current Time Zone: {currentTimeZone.DisplayName}, Offset from UTC: {offsetFromUtc}");

  15. Locate the following code comment:

     // TASK 1: Step 5 - Convert the current time to UTC and display it

  16. To convert the current time to UTC and display it, add the following code below the comment:

    DateTime utcTime = DateTime.UtcNow;
Console.WriteLine($"UTC Time: {utcTime}");

  17. Save the Program.cs file.

  18. Run your app and review the output.

    You should see output (for the current date) that’s similar to the following:

     Demonstrate date and time operations:
