从早上开始，我就一直在为这个问题而苦苦挣扎。我的域服务中有以下课程。

 [MetadataTypeAttribute(typeof(CompanyRecord.CompanyRecordMetadata))]
 public partial class CompanyRecord
 {

     // This class allows you to attach custom attributes to properties
     // of the CompanyRecord class.
     //
     // For example, the following marks the Xyz property as a
     // required property and specifies the format for valid values:
     //    [Required]
     //    [RegularExpression("[A-Z][A-Za-z0-9]*")]
     //    [StringLength(32)]
     //    public string Xyz { get; set; }
    internal sealed class CompanyRecordMetadata
    {
        // Metadata classes are not meant to be instantiated.
        private CompanyRecordMetadata()
        {
        }

        public string PostalCode { get; set; }

        public string Province { get; set; }

        public string Website { get; set; }

        public int MarketID { get; set; }

        public int AffiliationID { get; set; }

        public string CallLetter { get; set; }
    }
}

问题：我需要创建一个验证规则，仅当 CompanyTypeID 等于 1、3、5、9 和 11 时才需要 MarketID 和 Affiliation ID 是否有人知道如何解决这个问题？
