推荐答案

也许可以在您的模型中尝试一下:

Maybe try this in your model:

[Required]
public bool Saturday{ get; set; }

[Required]
public bool Sunday{ get; set; }

[NotMapped]
public bool SatSun
{
    get
    {
        return (!this.Saturday && !this.Sunday);
    }
}

[RequiredIf("SatSun",true)]
public string Holiday{ get; set; }
