Understanding the Difference IActionResult and IResult in ASP.NET Core

When working with ASP.NET Core, developers often come across two similar interfaces – IActionResult and IResult. While both interfaces are used to return results from an action method, are some key differences between them that are important to understand.

The IActionResult interface is a base interface that represents the result of an action method. It provides a way to return different types of results, such as a ViewResult, JsonResult, or RedirectResult, depending on the specific needs of the action method.


public IActionResult MyAction()
{
    // Perform some logic

    return View();
}

In the above example, the MyAction method a ViewResult, which represents a view that will be rendered and returned to the client. This is a common scenario when working with MVC applications.

On the other hand, the IResult interface is a more generic interface that represents the result of an action method without specifying the type of result. It is often used when the specific type of result is not known or when the action method needs to return a custom result type.


public IResult MyAction()
{
    // Perform some logic

    return new CustomResult();
}

In this example, the MyAction method returns a custom result type, which implements the IResult interface. This allows developers to define own result types and have more control over the returned result.

Choosing between IActionResult and IResult

So, when should you use IActionResult and when should you use IResult? The answer depends on the specific requirements of your application.

If you are working with an MVC application and need to return different types of results, such as views, JSON data, or redirects, then IActionResult is the appropriate choice. It provides a clear and concise way to specify the type of result being returned.

On the other hand, if you are working with a more generic or custom scenario the specific type of result is not known or needs to be customized, then IResult can be used. It allows for more flexibility and in defining and custom result types.

Conclusion

In summary, the IActionResult and IResult interfaces in ASP.NET Core different ways to return results from action . While IActionResult is used to return specific types of results, such as views or JSON data, IResult is a more generic interface that allows for custom result types. Choosing between the two depends on the specific requirements of your application and the level of control you need over the returned result.
