Then just use the validation anotations available or create your own! ``` csharp namespace EntityValidation.Examples { public class Entity : Validate<Entity> { public int Id { get; set; } [Mandatory] public string Name { get; set; } [StrongPassword(true, true, true, 8, "Password must be strong")] public string Password { get; set; } [Cpf] public string Cpf { get; set; } [Cnpj] public string Cnpj { get; set; } [Email] public string Email { get; set; } [Between(1, 1.5)] public double Between { get; set; } } } ``` With the inheritance and the class anotations, you will be apt to use the **IsValid** method that will return a bool if the conditions were atended or not. If one of the conditions are not atended a property **Errors** will be filled with errors messages ```csharp var entity = new Entity { Name = "Victor", Password = "!23vDasc@", Between = 1, Cnpj = "001", Cpf = "111.222.444-77", Email = "philippe.silva@domain" }; // if every property marked with an anotation is Valid if (entity.IsValid) { //do something } ``` # Create your own Validation To create your own validation, just create a class and then inherit **Attribute** and **IAttribute**, the code below from the Mandatory validation class can be used as an example. Implementing this two inheritance you will need to implement the Message property and the IsValid method. The IsValid method will be were the magic will happen, where you will validate and return a bool if the your validation is accomplished. The Message is the error message that will be added in the Errors property automaticaly if the IsValid return false. ```csharp using System; using EntityValidation.Interface; namespace EntityValidation.Attributes { public sealed class Mandatory : Attribute, IAttribute { public Mandatory(string message = "The {0} is required") { Message = message; } public string Message { get; } public bool IsValid(object value) { return value != null; } } } ``` https://www.myget.org/Feed/Details/entity-validation/
