Question

为了掌握MDS WCF API，我启动了一个.Net Core控制台应用程序。我很难找到有关API中使用的数据结构的详细文档。我现在有一个简单的函数，它使用 EntityMembersGet 来读取某个实体的成员（行）。 MDS服务返回数据，但是当我尝试读取/显示数据时，我无法弄清楚如何显示域属性的值。要显示属性的值，我使用 EntityMembers.Members.Attributes []。值，当属性是Freefrom属性时，它可以正常工作。但是，当Attribute是Domain属性时，使用EntityMembers.Members.Attributes []。Value返回“MDService.MemberIdentifier”。所以，我的问题是，我如何获得域属性的值？

我已经分享了我的代码和输出。

作为第二个问题，如果有人能够向我指出MDS WCF API的更具描述性的文档，那将会很棒。

 public static async Task ReadRecordsAsync()
    {
        EntityMembersGetRequest getRequest = new EntityMembersGetRequest();
        EntityMembersGetResponse getResponse = new EntityMembersGetResponse();

        EntityMembersGetCriteria membersGetCriteria = new EntityMembersGetCriteria
        {
            ModelId = new Identifier() { Name = "Model1" },
            EntityId = new Identifier() { Name = "Entity1" },
            VersionId = new Identifier() { Name = "VERSION_1" },
            MemberType = MemberType.Leaf,
            MemberReturnOption = MemberReturnOption.DataAndCounts
        };

        getRequest.MembersGetCriteria = membersGetCriteria;
        //EntityMembersGetResponse getResponse = await mdsProxy.EntityMembersGetAsync(getRequest);
        getResponse = await mdsProxy.EntityMembersGetAsync(getRequest);

        Console.WriteLine("Member information: \n Membercount: {0} | TotalPages: {1}", getResponse.EntityMembersInformation.MemberCount, getResponse.EntityMembersInformation.TotalPages);
        //Console.WriteLine("Members: \n Count: {0}", getResponse.EntityMembers.Members.Count.ToString());

        if (getResponse.EntityMembers.Members.Count > 0)
        {              
            foreach (Member individualMember in getResponse.EntityMembers.Members)
            {
                Console.WriteLine("----------");
                Console.WriteLine("Individual Member: \n Id: {0} | Code: {1} | Name: {2}",
                    individualMember.MemberId.Id, 
                    individualMember.MemberId.Code,
                    individualMember.MemberId.Name);
                for (int i = 0; i < individualMember.Attributes.Count; i++)
                {
                    Console.WriteLine("Attributes ({0}): \n Id Id: {1} | Id name: {2} | Type: {3} | Value: {4} \n ",
                        i,
                        individualMember.Attributes[i].Identifier.Id,
                        individualMember.Attributes[i].Identifier.Name,
                        individualMember.Attributes[i].Type,
                        individualMember.Attributes[i].Value
                        );
                    if (individualMember.Attributes[i].Type == AttributeValueType.Domain)
                    {
                        Console.WriteLine("Domain attribute");
                    }
                }
            }

运行应用程序时的输出：请参阅Domain属性输出的“Attributes（2）”行的末尾。

Answer 1

在GitHub上浏览SQL的Feature示例，我找到了问题的答案。当属性是Domain属性时，您可以使用MemberIdentifier类来获取属性的属性：

if (Attribute.Type == AttributeValueType.Domain)
{
   MemberIdentifier dbaMemberId = (MemberIdentifier)anAttribute.Value;
   Console.WriteLine("Attribute Value:{0}", dbaMemberId.Code);
}

我希望这有助于其他人寻找此类信息。
