Is it possible to override the required attribute on a property in a model?

Question

I\'m curious to find out if it is possible to override the [Required] attribute that has been set on a model. I\'m sure there most be a simple solution to this problem, any

Answer 1

@HackedByChinese method is fine, but it contains a problem

public class BaseModel
{
    [Required]
    public string RequiredProperty { get; set; }
}

public class DerivativeModel : BaseModel
{
    new public string RequiredProperty { get; set; }
}

This code give you a validation error in ModelState EVEN if you use DerivativeModel on the form, override doesn't work either, so you cannot delete Required attribute by overriding or renewin it, so I came to a some sort of a workaround

public class BaseModel
{
    public virtual string RequiredProperty { get; set; }
}

public class DerivativeModel : BaseModel
{
    [Required]
    public override string RequiredProperty { get; set; }
}

public class DerivativeModel2 : BaseModel
{
    [Range(1, 10)]
    public override string RequiredProperty { get; set; }
}

I have a base model with no validation attributes and derived classes
