public class CustomValidationAttribute : ValidationAttribute
{
    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        // 多个值的验证逻辑
        // ...
        
        if (/* 验证成功 */)
        {
            return ValidationResult.Success;
        }
        else
        {
            return new ValidationResult(ErrorMessage);
        }
    }
}

public class MyModel

    [CustomValidation(ErrorMessage = "验证失败")]
    public string Property1 { get; set; }
    
    [CustomValidation(Param1 = "value1", Param2 = "value2", ErrorMessage = "验证失败")]
    public string Property2 { get; set; }
