我试图传递一个大字符串(24,000到50,000个字符)到自托管的TCP WCF服务。
我已经将maxStringContentLength(无处不在)升高到22008192。
我读某处，我需要将bindingConfiguration更改为“LargeBuffer”或“LongFields”，但当我这样做：
<endpoint address="" binding="netTcpBinding" bindingConfiguration="LongFields" contract="ExStreamWCF.IService1">
或这个：
<endpoint address="" binding="netTcpBinding" bindingConfiguration="LargeBuffer" contract="ExStreamWCF.IService1">
我的服务不会启动。我真的需要这个错误消失。有任何想法吗？
谢谢，
杰森
PS – 服务器上tcp服务的配置文件：
<system.serviceModel>
<services>
<service behaviorConfiguration="ExStreamWCF.Service1Behavior"
name="ExStreamWCF.Service1">
<endpoint address="" binding="netTcpBinding" bindingConfiguration=""
contract="ExStreamWCF.IService1">
<identity>
<dns value="Devexstream-2.anchorgeneral.local" />
<!--<dns value="vmwin2k3sta-tn2" />-->
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://Devexstream-2:8080/Service" />
<!--<add baseAddress="net.tcp://vmwin2k3sta-tn2:8080/Service" />-->

编辑：根据要求绑定
<system.serviceModel>
<bindings>
<netTcpBinding>

客户端终端：
<client>
<endpoint address="net.tcp://devexstream-2:8080/Service" binding="netTcpBinding"
bindingConfiguration="NetTcpBinding_IService1" contract="TCPService.IService1"
name="NetTcpBinding_IService1">
<identity>
<servicePrincipalName value="TCPService\Devexstream-2" />
<dns value="Devexstream-2.anchorgeneral.local" />
</identity>
</endpoint>
我编辑了服务(如下)，但现在服务不会启动。新的app.config：
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="ExStreamWCFBinding" closeTimeout="00:00:05" openTimeout="00:00:05" receiveTimeout="00:00:05" sendTimeout="00:00:05" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparison="StrongWildCard" maxBufferPoolSize="524288" maxBufferSize="524288" maxConnections="10" maxReceivedMessageSize="5242880">
<readerQuotas maxDepth="32" maxStringContentLength="5242880" maxArrayLength="16384" maxBytesPerRead="4096" maxNaMetableCharCount="16384" />
</binding>
</netTcpBinding>
</bindings>
<services>
<service behaviorConfiguration="ExStreamWCF.Service1Behavior"

<endpoint address="" binding="netTcpBinding" bindingConfiguration="ExStreamWCFBinding"

<identity>
<dns value="Devexstream-2.anchorgeneral.local" />
<!--<dns value="vmwin2k3sta-tn2" />-->

</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""

<!--<add baseAddress="net.tcp://vmwin2k3sta-tn2:8080/Service" />-->
</baseAddresses>
</host>
</service>
</services>
<behaviors>

bindingConfiguration需要有你分配给netTcpinding元素的名称 – “LargeBuffer”或“LongFields”不会意味着任何东西，除非配置文件中有一个绑定元素。这就是为什么你的服务不会开始，当你把它 – 你很可能有一些配置错误消息，我打赌。
要覆盖maxStringContentLength的默认8192设置，请执行以下操作：
>在配置文件中创建一个Binding元素，该元素具有您想要的maxStringContentLength的大小，并在name属性中为其指定名称。
>在endpoint元素中，将名称从上面的步骤1分配给属性bindingConfiguration。
如果不为端点指定绑定配置，则服务将使用默认值。
例如，拿你的配置文件上面。在标记下，添加以下绑定配置(请注意，您使用的具体值和可选属性将根据服务的需要而有所不同)：
<bindings>
<netTcpBinding>
<binding name="ExStreamWCFBinding" closeTimeout="00:00:05" openTimeout="00:00:05" receiveTimeout="00:00:05" sendTimeout="00:00:05" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparison="StrongWildCard" maxBufferPoolSize="524288" maxBufferSize="524288" maxConnections="10" maxReceivedMessageSize="5242880">
<readerQuotas maxDepth="32" maxStringContentLength="5242880" maxArrayLength="16384" maxBytesPerRead="4096" maxNaMetableCharCount="16384" />
</binding>
</netTcpBinding>
</bindings>
然后在定义端点时：
<endpoint address="" binding="netTcpBinding" bindingConfiguration="ExStreamWCFBinding" contract="ExStreamWCF.IService1">
已更改为添加
根据您的附加信息，在您的服务的端点上绑定bindingConfiguration属性值“NetTcpBinding_IService1”。
