我有一个WCF服务，从数据库返回1000条记录到客户端。我有一个ASP。NET WCF客户端(我已经在asp.net web应用程序项目中添加了服务引用来使用WCF)。
当我运行客户端应用程序时，我得到以下消息:
传入消息的最大消息大小配额(65536)已为 超过了。如果需要增加配额，使用 MaxReceivedMessageSize属性 适当的绑定元素。
任何帮助吗?如何增加消息大小配额?

我解决了我的问题在必应地图WPF在我的项目使用CalculateRoute()。 在我的案例中的解决方案是设置maxReceivedMessageSize和maxReceivedMessageSize属性“httpTransport”为“customBinding”部分。
我设置了应用程序。配置文件。配置myApp.config)

当我在web.config上使用这个设置时，我得到了这个错误
System.ServiceModel.ServiceActivationException
我像这样设置设置:
<service name="idst.Controllers.wcf.Service_Talks">
<endpoint address="" behaviorConfiguration="idst.Controllers.wcf.Service_TalksAspNetAjaxBehavior"
binding="webHttpBinding" contract="idst.Controllers.wcf.Service_Talks" />
</service>
<service name="idst.Controllers.wcf.Service_Project">
<endpoint address="" behaviorConfiguration="idst.Controllers.wcf.Service_ProjectAspNetAjaxBehavior"
binding="basicHttpBinding" bindingConfiguration="" bindingName="largBasicHttp"
contract="idst.Controllers.wcf.Service_Project" />
</service>
</services>
<bindings>
<basicHttpBinding>
<binding name="largBasicHttp" allowCookies="true"
maxReceivedMessageSize="20000000"
maxBufferSize="20000000"
maxBufferPoolSize="20000000">
<readerQuotas maxDepth="32"
maxArrayLength="200000000"
maxStringContentLength="200000000"/>
</binding>
</basicHttpBinding>
如果你正在动态创建你的WCF绑定，下面是使用的代码:
BasicHttpBinding httpBinding = new BasicHttpBinding();
httpBinding.MaxReceivedMessageSize = Int32.MaxValue;
httpBinding.MaxBufferSize = Int32.MaxValue;
// Commented next statement since it is not required
// httpBinding.MaxBufferPoolSize = Int32.MaxValue;
<bindings>
<wsHttpBinding>
<binding name="wsHttpBinding_Username" maxReceivedMessageSize="20000000" maxBufferPoolSize="20000000">
<security mode="TransportWithMessageCredential">
<message clientCredentialType="UserName" establishSecurityContext="false"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint
binding="wsHttpBinding"
bindingConfiguration="wsHttpBinding_Username"
contract="Exchange.Exweb.ExchangeServices.ExchangeServicesGenericProxy.ExchangeServicesType"
name="ServicesFacadeEndpoint" />

WCF测试客户端有自己的客户端配置。
运行测试客户端并滚动到底部。 如果双击Config File节点，您将看到XML表示。正如您所看到的，maxReceivedMessageSize是65536。
要编辑它，右键单击配置文件树节点并选择用SvcConfigEditor编辑。 当编辑器打开Bindings时，展开Bindings并双击自动生成的绑定。
您可以在这里编辑所有属性，包括maxReceivedMessageSize。当你完成后，点击文件-保存。
最后，当您回到WCF测试客户端窗口时，单击工具-选项。
注意:当启动服务时，取消选中Always generate配置。
