Wcf 事务仅在客户端启动

我需要实现以下场景： 若客户机启动了事务，它将流向服务器，但若客户机并没有启动事务，那个么服务方法必须在并没有事务的情况下执行。可能吗？在我的例子中，没有TransactionScopeRequired=true，事务就不会流动

服务器：

<system.serviceModel> <bindings> <netTcpBinding> <binding name="tcpTransactional" transactionFlow="true" /> </netTcpBinding> </bindings> <services> <service name="WcfServiceLibrary1.TcpTransactionalService"> <endpoint address="" binding="netTcpBinding" bindingConfiguration="tcpTransactional" contract="WcfServiceLibrary1.ITcpTransactionalService"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary1/TcpTransactionalService/" /> <add baseAddress="net.tcp://localhost:8730/Design_Time_Addresses/WcfServiceLibrary1/TcpTransactionalService/" /> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior> <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> <serviceMetadata httpGetEnabled="True"/> <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> <serviceDebug includeExceptionDetailInFaults="False" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> [ServiceContract] public interface ITcpTransactionalService { [OperationContract] [TransactionFlow(TransactionFlowOption.Allowed)] void DoWork(); } //[OperationBehavior(TransactionScopeRequired = true)] public void DoWork() { Debug.Assert(Transaction.Current != null); Debug.Assert(Transaction.Current.TransactionInformation.DistributedIdentifier != Guid.Empty); } [服务合同] 公共接口ITcpTransactionalService { [经营合同] [TransactionFlow（TransactionFlowOption.Allowed）] 无效销钉（）； } //[操作行为（TransactionScopeRequired=true）] 公共工作 { Assert（Transaction.Current！=null）； Assert（Transaction.Current.TransactionInformation.DistributeIdentifier！=Guid.Empty）； } 客户：

<system.serviceModel> <bindings> <netTcpBinding> <binding name="NetTcpBinding_ITcpTransactionalService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="true" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Transport"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://localhost:8730/Design_Time_Addresses/WcfServiceLibrary1/TcpTransactionalService/" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_ITcpTransactionalService" contract="TcpTransactionalService.ITcpTransactionalService" name="NetTcpBinding_ITcpTransactionalService"> <identity> <dns value="localhost" /> </identity> </endpoint> </client> </system.serviceModel> private static void TestTcp() { using (var scope = new TransactionScope()) { var client = new TcpTransactionalService.TcpTransactionalServiceClient(); client.DoWork(); Debug.Assert(Transaction.Current != null); Debug.Assert(Transaction.Current.TransactionInformation.DistributedIdentifier != Guid.Empty); scope.Complete(); } } 私有静态void TestTcp（） { 使用（var scope=new TransactionScope（）） { var client=new TcpTransactionalService.TcpTransactionalServiceClient（）； client.DoWork（）； Assert（Transaction.Current！=null）； Assert（Transaction.Current.TransactionInformation.DistributeIdentifier！=Guid.Empty）； scope.Complete（）； } }

使用TransactionScopeRequire=true

如果客户端不发送事务，则不会以分布式事务结束。如果是这样的话，你也会这样做

现在，这仍将调用本地事务中的操作。如果要禁止此操作，请检查分布式标识符。如果其Guid.Empty为空，请在另一个创建如下的TransactionScope中运行其余代码：

 if (Transaction.Current.TransactionInformation.DistributedIdentifier == Guid.Empty)
 {
    using (var scope = new TransactionScope(TransactionScopeOption.Suppress))
    {
       DoWork();
       scope.Complete();
    }
 }
 else
 {
        DoWork();
 }
