Data validation refers to the processing of data in a program's operations to ensure that it is clean, correct, and useful. Most. NET developers use data annotation validation. But Nopcommerce is using Fluent Validation. It's a small one. NET validation libraries, using the fluent interface and lambda expressions to generate validation rules for business objects. To add a validation to the Nopcommerce model, you need to complete the following two steps:

1. Create a Abstractvalidator derived class that contains all the validation logic. As shown below:

   public class addressvalidator:abstractvalidator<addressmodel>    {public        addressvalidator ( Ilocalizationservice localizationservice)        {            rulefor (x = x.firstname)                . Notempty ()                . Withmessage (Localizationservice.getresource ("Address.Fields.FirstName.Required"));        }    }

2. Mark your model class with a validation attribute. As shown below:

    [Validator (typeof (Addressvalidator))]    public class Addressmodel:basenopentitymodel    {

When the view model is passed to the controller, ASP. NET will be properly validated.
