C sharp validating

In general, it’s critical to protect the business login.This can be accomplished with various services, managers, providers, stores, etc.

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.
