Depending on the project at hand, there are many approaches to validating data inputs.

There is no right way to validate user input, so working with an experienced team is a great way to understand which tools are right for the job at hand.

Here are three ways for validating business methods/functions: Exception Throwing Validation This approach involves a direct system interrupt by using Exception.

But I have modified it for the purpose of data validation.

Here is the way the upper example can be written with this pattern: private IValidator _validator; Result Update User Name Async(int user Id, string user Name) public class Identifier Should Be Positive : IValidation Rule public class String Should Not Be Null Or White Space: IValidation Rule This approach relies on the fact that almost all of your services must return some kind of result. This is the perfect opportunity to use the C# feature of extensions that adds validation and mapping methods.
