我将 WCF 与 Code First 结合使用(VS 2012、.NET 4.0、WCF 5)。除非我想转移一个大物体,否则一切正常。它包含许多其他对象的列表。每个对象只有很小的内容。如果此列表超过 127 个对象,则会出现异常:
服务器没有提供有意义的回复;这可能是由于合同不匹配、会话过早关闭或内部服务器错误造成的。
我通过减少数据库中的列数(尝试和错误)发现了这一点。
我在客户端使用以下配置:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBinding_****_Service" closeTimeout="00:00:10"
openTimeout="00:00:10" receiveTimeout="00:05:00" sendTimeout="00:05:00"
maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
</binding>
</netTcpBinding>
</bindings>
<client>
<endpoint address="net.tcp://localhost:8000/****" binding="netTcpBinding"
bindingConfiguration="****" contract="****"
name="NetTcpBinding_****Service">
<identity>
<userPrincipalName value="****" />
</identity>
</endpoint>
</client>
</system.serviceModel>
服务器配置如下所示:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBinding_****_Service" closeTimeout="00:00:10"
openTimeout="00:00:10" receiveTimeout="00:05:00" sendTimeout="00:05:00"

请原谅掩盖了一些名字。我需要避免人们可以从这些名称中得出关于该项目的推论。:D
