从早上起，我一直在努力解决这个问题。我的域名服务中有以下课程。
[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()

问题：我需要创建一个验证规则，只有当CompanyTypeID相当于1,3,5,9和11时才需要MarketID和Affiliation ID才有人知道如何解决这个问题？< / p>
