WCF服务接口多，客户端在引用时出错！报WCF The maximum nametable character count quota (16384) has been exceeded while reading XML data错误

在服务端中定义接口太多时，在客户端的服务引用时，报错误:

元数据包含无法解析的引用:“net.tcp://localhost:8081/BaseData/mex”。    XML 文档中有错误。    读取 XML 数据时，超出最大名称表字符计数配额 (16384)。名称表是用于存储在处理 XML 时所遇到的字符串的数据结构 - 具有非重复元素、属性名称和属性值的长 XML 文档可能会触发此配额。通过更改在创建 XML 读取器时所使用的 XmlDictionaryReaderQuotas 对象的 MaxNameTableCharCount 属性，可增加此配额。

解决方法：

服务端配置文件：

<system.serviceModel>

    <services>

      <!--基础数据服务-->

      <service name="PmsWcfServer.PmsWcfBaseData" behaviorConfiguration="WcfBaseData">

        <host>

          <baseAddresses>

            <add baseAddress="net.tcp://127.0.0.1:8081"/>

          </baseAddresses>

        </host>

        <endpoint address="" binding="netTcpBinding"  contract="PmsWcfServer.IPmsWcfBaseData" bindingConfiguration="BindBaseData"/>

        <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>

      </service>

    </services>

 

    <behaviors>

      <serviceBehaviors>

        <behavior name="WcfBaseData">

          <serviceDebug includeExceptionDetailInFaults="true"/>

          <serviceMetadata httpGetEnabled="false"/>

          <serviceCredentials>

            <serviceCertificate x509FindType="FindBySubjectName" findValue="PmsWcfServer" storeLocation="LocalMachine"/>

            <userNameAuthentication userNamePasswordValidationMode="Custom"  customUserNamePasswordValidatorType="PmsWcfServer.CheckUserNamePass,PmsWcfServer"/>

          </serviceCredentials>

        </behavior>

      </serviceBehaviors>

     

      <endpointBehaviors>

        <behavior name="BindBaseData">

          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>

        </behavior>

      </endpointBehaviors>

    </behaviors>

   

    <bindings>

      <netTcpBinding>

        <binding name="BindBaseData" maxReceivedMessageSize="2147483647">

          <security mode="Message">

            <message clientCredentialType="UserName"/>

          </security>

<!--注意：红色字体，这里必须要修改maxNameTableCharCount值，增大配额-->

          <readerQuotas maxNameTableCharCount="2147483647" maxStringContentLength="2147483647" maxBytesPerRead="2147483647" maxArrayLength="2147483647" maxDepth="32000"/>

        </binding>

      </netTcpBinding>

    </bindings>

  </system.serviceModel>

    只是修改以上配置文件，客户端依然后引用不成功，还需要修改:C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe.Config文件，在文件后面增加以下节:

   <system.serviceModel> 

    <bindings> 

      <netTcpBinding> 

        <binding name="BindSystem" maxBufferPoolSize="2147483647" 

          maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> 

          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" 

            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> 

          <security mode="None" /> 

        </binding> 

      </netTcpBinding> 

    </bindings> 

    <client> 

      <endpoint binding="netTcpBinding" bindingConfiguration="BindSystem" 

        contract="IMetadataExchange" name="net.tcp" /> 

    </client> 

  </system.serviceModel>

重启VS，后再次引用成功！
