C sharp asp net core 7 web api change datetime format to customize

Introduction

ASP.NET is a popular programming language used for building web applications. In this article, we will explore how to change the format in an ASP.NET Core 7 web API to it according to our requirements.

Step 1: Understanding DateTime Format

we dive into the code, let's understand the DateTime format in ASP.NET. DateTime is a data type used to represent dates and times. By default, ASP.NET uses a standard format to display DateTime . However, we can customize this format to suit our needs.

Step 2: DateTime Format

To change the DateTime format in an ASP.NET Core 7 web API, we need to modify the code the DateTime value is being displayed or serialized. Let's consider an example where we have a DateTime property in our model and we want to customize its format.


public class MyModel
{
    public DateTime MyDateTime { get; set; }
}

In the above code snippet, we have a MyModel class with a property named MyDateTime of type DateTime.

Step 3: Customizing DateTime Format

To customize the DateTime format, we can use the ToString() method with a format string. The format string specifies how the DateTime value should be displayed. Let's modify our MyModel class to include a formatted string representation of the DateTime property.


public class MyModel
{
    private DateTime _myDateTime;

    public DateTime MyDateTime
    {
        get { return _myDateTime; }
        set { _myDateTime = value; }
    }

    public string FormattedDateTime
    {
        get { return _myDateTime.ToString("dd/MM/yyyy HH:mm:ss"); }
    }
}

In the above code snippet, we have added a new property named FormattedDateTime, which returns the DateTime value in the desired format using the ToString() method with the format string “dd/MM/yyyy HH:mm:ss”.

Step 4: Using the Customized DateTime Format

Now that we have customized the DateTime format, let's see how we can use it in our ASP.NET Core 7 web API. Suppose we have a controller action that returns a JSON response containing the MyModel object.


[HttpGet]
public IActionResult Get()
{
    MyModel model = new MyModel
    {
        MyDateTime = DateTime.Now
    };

    return Ok(model);
}

In the above code snippet, we a new instance of the MyModel class and set the MyDateTime property to the current DateTime value. We then return this model as an Ok response.

Step 5: Testing the Customized DateTime Format

Now, let's test our customized DateTime format by making a request to the API endpoint. When we receive the response, we should see the DateTime value in the format we specified.

For example, if we make a GET request to the API endpoint, we might receive the following JSON response:


{
    "myDateTime": "01/01/2023 12:34:56"
}

In the above response, the MyDateTime property is displayed in the format “dd/MM/yyyy HH:mm:ss” as we specified in our code.

Conclusion

By following the outlined in this article, we can easily change the DateTime format in an ASP.NET Core 7 web API to customize it according to our requirements. This allows us to display DateTime values in a format that is more for our application.
