从模型验证中排除字段 [英] Exclude Fields From Model Validation

问题描述

假设我有以下ViewModel:

    public class PersonViewModel
    {
        [Required]
        public String Email { get; set; }

        [Required]
        public String FirstName { get; set; }

        [Required]
        public String LastName { get; set; }
    }

这是一个ViewModel而不是原始的Entity，我在两个地方都使用了此模型，在第一个地方，我想验证所有字段，但是在另一个地方，我想从模型验证中排除Email字段.无论如何，有没有要指定从验证中排除字段?

This is a ViewModel not a original Entity, I use this model in two places, in the first one I want to validate all fields, but in another one I want to exclude Email field from model validation. Is there anyway to specify to exclude field(s) from validation?

推荐答案

您可以使用

ModelState.Remove("Email");

删除模型状态下与隐藏字段相关的条目.

to remove entries in model state, that are related to hidden fields.

最好的解决方案是将视图模型分为两个:

The best solution is to divide view model into two:

public class PersonViewModel
{
    [Required]
    public String FirstName { get; set; }

    [Required]
    public String LastName { get; set; }
}

public class PersonWithEmailViewModel : PersonViewModel
{
    [Required]
    public String Email { get; set; }
}
