ASP.NET 6.0 - Build Hands-On Web Projects - Add Validation Attributes to Order Class

This video tutorial covers the implementation of data annotation validation attributes for an order model in a Visual Studio project. It explains the importance of validation attributes, how to set them up, and their role in server-side validation. The tutorial walks through adding validation rules for fields like customer ID and order cost, using error messages and regular expressions to ensure data integrity.

What is the primary purpose of data annotation validation attributes in the context of the order model?

• To encrypt sensitive data

• To improve database performance

• To specify validation rules for model properties

• To enhance the user interface design

Which library is necessary to use data annotation validation attributes in a Visual Studio project?

• System.IO

• System.Net

• System.ComponentModel.DataAnnotations

• System.Text

Why is it unnecessary to add a validation attribute for the ID property in the order model?

• Because it is always a string

• Because it is not used in the application

• Because it is automatically generated by the server

• Because it is a primary key and non-null by default

What error message is suggested for a missing customer ID in the order model?

• Please enter a valid email address

• Please enter a valid postal code

• Please provide a valid phone number

• Please put the customer ID for this order

What data type should the order cost be validated as?

• Decimal

• Boolean

• String

• Integer

What is the purpose of using a regular expression for the order cost?

• To convert the cost to a string

• To validate the cost as a decimal with two decimal places

• To allow any alphanumeric value

• To ensure the cost is a positive integer

What is the final step to ensure the data annotation validation attributes are correctly implemented?

• Running a security scan

• Building the application with Control + Shift + B

• Writing unit tests for each attribute

• Deploying the application to the server
