ASP.NET MVC ValidationAttribute获取其他属性显示名称

public class CustomValidationAttribute : ValidationAttribute
{
    public string OtherPropertyName { get; set; }

    public CustomValidationAttribute(string otherPropertyName)
    {
        OtherPropertyName = otherPropertyName;
    }

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        var otherProperty = validationContext.ObjectType.GetProperty(OtherPropertyName);
        var displayName = otherProperty.GetCustomAttribute<DisplayAttribute>()?.Name;

        // 在这里编写自定义验证逻辑，并使用displayName作为其他属性的显示名称
    }
}

public class MyModel
{
    [Display(Name = "First Name")]
    public string FirstName { get; set; }

    [CustomValidation(OtherPropertyName = "FirstName")]
    public string LastName { get; set; }
}
