我正在尝试使用BufferSize，因此我可以从SQL数据库中获取所有数据。这是我的配置文件：

我收到的错误是第3行的配置绑定有问题。
答案 0 :(得分：1)
<bindings>
<basicHttpBinding>
那些只能定义一次，并且应该在system.serviceModel节点内。
答案 1 :(得分：1)
<bindings>标记不能低于<configuration>标记 - 它是<system.serviceModel>的孩子 - 因此您看到错误。
此外，正如您在配置中定义的那样，您指定的绑定（使用较大的配额）将不，因为它既不是默认绑定（默认绑定省略name属性）也不是通过bindingConfiguration属性分配给端点。这意味着您将获得basicHttpBinding的默认值（大大降低）。
对配置文件进行两处更改 - 首先，将<bindings>从<configuration>下方移至<system.serviceModel>以下。其次，将“basicHttp”绑定分配给端点。
最后的注释 - 看起来这是来自WCF服务库项目（即类库）的app.config。根据配置文件中的注释，您需要将<system.serviceModel>部分移动到托管服务的应用程序的配置文件，因为类库不使用配置文件。
你<system.serviceModel>应该如下所示：
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="basicHttp" allowCookies="true"
maxReceivedMessageSize="20000000"
maxBufferSize="20000000"
maxBufferPoolSize="20000000">
<readerQuotas maxDepth="32"
maxArrayLength="200000000"
maxStringContentLength="200000000"/>
</binding>
</basicHttpBinding>
</bindings>
<services>
<service name="WCF_Services_library.Service1">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8733/Design_Time_Addresses/WCF_Services_library/Service1/" />
</baseAddresses>
</host>
<endpoint address="" binding="basicHttpBinding"
bindingConfiguration="basicHttp"
contract="WCF_Services_library.IService1" />
<!-- Metadata Endpoints -->
<endpoint address="mex" binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" />
<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
请注意，<bindings>部分现在位于<system.serviceModel>下，并且“basicHttp”绑定配置通过bindingConfiguration属性分配给您的终端。
答案 2 :(得分：0)
您必须符合以下配置
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="NewBinding0" />
</basicHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="WCF_Services_library.Service1Behavior"
name="WCF_Services_library.Service1">
<endpoint address="http://localhost:8733/Design_Time_Addresses/WCF_Services_library/Service1"
binding="basicHttpBinding" bindingConfiguration="NewBinding0"
contract="WCF_Services_library.IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8733/Design_Time_Addresses/WCF_Services_library/Service1/" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WCF_Services_library.Service1Behavior">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
你应该把代码放在system.serviceModel标签
之间
