Question

我在CF文档，常见问题解答，博客和SO条目中到处搜索，但仍然无法理解为什么这个模型：

    <cf:project defaultNamespace="Humanisme" xmlns:cf="http://www.softfluent.com/codefluent/2005/1" xmlns:cfx="http://www.softfluent.com/codefluent/modeler/2008/1" xmlns:cfom="http://www.softfluent.com/codefluent/producers.model/2005/1" xmlns:cfps="http://www.softfluent.com/codefluent/producers.sqlserver/2005/1" xmlns:cfsm="http://www.softfluent.com/codefluent/producers.servicemodel/2007/1" defaultKeyPropertyTypeName="int" defaultMaxLength="240" persistencePropertyNameFormat="{1}" createDefaultMethodForms="true" createDefaultApplication="false" createDefaultHints="false">

    </cf:configuration>
  </cf:producer>

(....)

<cf:entity name="EtapaVital" namespace="Humanisme" categoryPath="/Humanisme">
    <cf:property name="Id" key="true" />
    <cf:property name="Nom" />
    <cf:property name="Idioma" typeName="{0}.EtapaVitalIdiomaCollection" relationPropertyName="Etapa" />
    <cf:property name="Documents" typeName="{0}.DocumentCollection" relationPropertyName="EtapaVital" />
  </cf:entity>

渲染到这些序列化属性：

RowVersion和EntityState获取序列化属性。

EntityDisplayName没有。

模型表面“属性”窗口似乎没有相关的属性选项，我无法在cfp文件中找到xml标签或属性。

如果您能给我任何线索或参考，从哪里开始学习在课程中导致这些输出的CodeFluent模型选项，我将非常感激。

再次感谢，我真的变成了CodeFluent爱好者！

Core Animation属性由CodeFluent实体生成，因为您将并发模式设置为init（documentation）。如果您没有此属性的最新值，则无法保存实体（RowVersion）。所以这个属性需要序列化。

Optimistic用于UI目的。其值由一个或多个属性计算。因此，无需对其进行序列化，因为您可以计算客户端。

目前没有属性可以更改这些特定属性的序列化行为。但是，您可以编写自定义子生成器以在属性上添加/删除序列化属性。您将找到一个在属性（GitHub）

上添加Json.NET特定属性的示例

以下是一些更改序列化行为的属性：

CodeFluentConcurrencyException（实体）：确定此实体是否标记为可序列化
EntityDisplayName（实体）：确定是否必须序列化EntityKey
serializable（实体）：确定TypeName是否必须序列化
serializeEntityKey（财产）：documentation
serializeTypeName或serializationMode（Property）=＆gt;更喜欢使用dataMember
includeInSerialization（属性）：定义序列化时此属性的排序顺序
serializationMode（属性）：确定序列化时是否可以跳过属性
serializationOrder（Property）：确定非序列化属性的私有字段是否可序列化
serializationNullable（项目）：确定序列化回调方法是否公开（serializePrivateMember，publicSerializationCallbacks等。）

序列化属性
