Learning ASP.NET Web API (Video 19)

This video tutorial builds on previous lessons by adding filtering capabilities to an API. It explains the need for filters, how to implement them using LINQ, and how to test them using Postman. The tutorial also covers advanced filtering techniques, including the use of OData queries, and concludes with a brief overview of upcoming topics on security in Web APIs.

Why are filters important when dealing with large data collections?

• They make the API slower.

• They increase the size of the data collection.

• They allow users to find specific records without knowing exact details.

• They help in retrieving all records at once.

What is the role of LINQ in implementing search parameters?

• It is used to secure the data.

• It is used to paginate the data.

• It is used to filter the data.

• It is used to sort the data.

How can you test the API after implementing search parameters?

• By using a spreadsheet application.

• By using Postman to send requests.

• By using a web browser.

• By using a text editor.

What happens when you combine filtering, sorting, and paging in an API request?

• The API returns only the first record.

• The API returns all records without any order.

• The API returns a filtered and sorted subset of records based on the page size.

• The API returns records in a random order.

What is the future development mentioned for ASP.NET Core?

• Enhanced security features.

• Support for OData Libraries V4.

• Integration with mobile applications.

• Support for multiple languages.
