Dynamics 365 中的关系元数据

Question

有没有办法通过 C# 在动态 crm 中获取关系描述？

我查看了 OnetoManyMetadata 对象，但在任何地方都找不到。

var cl = new CrmServiceClient(...);
var q = new RetrieveEntityRequest { 
    EntityFilters = EntityFilters.Relationships, 
    LogicalName = "..." 
};
var r = (cl.Execute(q) as RetrieveEntityResponse).EntityMetadata;
var OtM = r.OneToManyRelationships;
var MtM = r.ManyToManyRelationships;
var MtO = r.ManyToOneRelationships;
