C# Custom Validators

πŸ”’πŸ”‘πŸ’Ό C# Custom Validators! πŸ’ΌπŸ”‘πŸ”’

🌍 In C#, custom validators are an essential tool for ensuring data integrity and enforcing specific validation rules within your applications.
🌎 Built-in validation attributes in C# are great, but they might not cover all your unique validation requirements. With custom validators, you have the freedom to define and implement your own rules tailored to your specific needs.
🌎 By encapsulating your validation logic within custom validators, you can reuse them across multiple projects and components

πŸ”Έ Step 1: Create a new class that inherits from the ValidationAttribute class.
πŸ”Έ Step 2: Implement the IsValid method to define your validation logic. You can leverage C#'s extensive features, such as regular expressions, comparisons, and more.
πŸ”Έ Step 3: Apply your custom validator to the appropriate properties or methods within your codebase by decorating them with your custom attribute.
πŸ”Έ Step 4: Handle validation errors by capturing exceptions or using the validation results to provide meaningful feedback to your users.
Lets Create a user class and validate Driving license if age is greater or equal to 18 else Driving License is not required for that user
