C#FluentValidation用于类的层次结构

本文介绍了C#FluentValidation用于类的层次结构的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个数据类层次结构

I have a hierarchy of data classes

public class Base { // Fields to be validated } public class Derived1 : Base { // More fields to be validated } public class Derived2 : Base { // More fields to be validated }

使用FluentValidation框架验证Derived1和Derived2而不复制基类字段的规则的合适方法是什么?

What would be the appropriate way to validated Derived1 and Derived2 using FluentValidation framework without duplicating rules for fields of Base class?

推荐答案

采取的一种方法如下:

public class Base { public string BaseName { get; set; } } public class Derived1 : Base { public string Derived1Name { get; set; } } public class BaseValidator<T> : AbstractValidator<T> where T : Base { public BaseValidator() { RuleFor(b => b.BaseName).NotNull(); } } public class Derived1Validator : BaseValidator<Derived1> { public Derived1Validator() { RuleFor(d => d.Derived1Name).NotNull(); } }

因此，您首先创建基本验证器，使其接受通用类型参数，并指定通用类型必须为base类型.为基类设置一般规则，然后继续.

So you first create your base validator, make it accept a generic type argument and specify that the generic type must be of type base. Set up your general rules for your base class and move on.

对于验证基类的子代的任何验证器，您都需要那些验证器从baseValidator继承，其中T将是您的派生类类型.

For any validators that validate children of your base class, you have those validators inherit from the baseValidator, where T will be your derived class type.
