RequiredIf条件验证属性 [英] RequiredIf Conditional Validation Attribute

问题描述

我一直在寻找到去落实，做以下验证属性的最佳方式了一些建议。

I was looking for some advice on the best way to go about implementing a validation attribute that does the following.

示范

public class MyInputModel 
{
    [Required]
    public int Id {get;set;}

    public string MyProperty1 {get;set;}
    public string MyProperty2 {get;set;}
    public bool MyProperty3 {get;set;}

}

我想有一个值ATLEAST为prop1 prop2 prop3如果prop3是唯一的价值填补它，它不应该等于假。
我将如何去为这个写一个验证属性（S？）？

I want to have atleast prop1 prop2 prop3 with a value and if prop3 is the only value filled it it should not equal false. How would i go about writing a validation attribute(s?) for this?

感谢您的帮助！

You may checkout the following blog post for a sample implementation of a [RequiredIf] custom validation attribute. It compares against a single other property value but you could easily tweak the IsValid method to meet your requirements.
