序列化属性

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使用此模型：

    <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:import path="Default.Surface.cfp" />
  <cf:producer name="Business Object Model (BOM)" typeName="CodeFluent.Producers.CodeDom.CodeDomProducer, CodeFluent.Producers.CodeDom">

      <subProducer typeName="CodeFluent.Producers.ServiceModel.ServiceProducer, CodeFluent.Producers.ServiceModel, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1bb6d7cccf1045ec" compileWithVisualStudio="true" compile="false" codeDomProviderTypeName="CSharp" targetDirectory="..\Humanisme.webApi" silverlightTargetVersion="Unspecified" dataAnnotationsProductionModes="NoAnnotations, All" jsonOptions="EnableJson" outputName="HumanismeService" cfx:targetProject="..\Humanisme.webApi\Humanisme.webApi.csproj" cfx:targetProjectLayout="Update" produceProxy="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>

呈现这些序列化属性：

RowVersion 和 EntityState 获取序列化属性。

EntityDisplayName 没有。

                this.OnPropertyChanged(new System.ComponentModel.PropertyChangedEventArgs("EntityState"));
            }
        }

模型表面似乎没有相关的属性选项 "Properties" window 而且我无法在cfp 文件。

如果您能给我任何线索或参考，我将非常感激从哪里开始学习导致类中这些输出的 CodeFluent 模型选项。

再次感谢，我真的要变成 CodeFluent 爱好者了！

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

EntityDisplayName 用于 UI 目的。它的值是根据一个或多个属性计算的。所以不需要序列化它，因为你可以在客户端计算它。

目前没有属性可以更改这些特定属性的序列化行为。但是，您可以将自定义子生产者写入属性的 add/remove 序列化属性。您会找到一个示例，该示例在属性 (GitHub)

上添加了 Json.NET 个特定属性

这里有一些属性可以改变序列化行为：

serializable（实体）：确定这个实体是否被标记为可序列化
serializeEntityKey (Entity)：判断EntityKey是否必须序列化
serializeTypeName（实体）：判断TypeName是否必须序列化
serializationMode (属性): documentation
dataMember 或 includeInSerialization (属性) => 更喜欢使用 serializationMode
serializationOrder(属性):定义这个属性序列化时的排序顺序
serializationNullable (属性): 确定序列化时是否可以跳过属性
serializePrivateMember(属性)：判断一个不可序列化的私有字段属性是否可序列化
publicSerializationCallbacks（项目）：判断序列化回调方法是否为public（OnEntityDeserializing、OnEntityDeserialized等）
