Handling Large Arrays in API V5 (.NET)

  • Article

When transferring large amounts of data (large arrays) in Version 5 of the API when using .NET, some changes to the client configuration may be necessary. The following elements may need to be adjusted in app.config, for example :

· MaxReceivedMessageSize

· MaxBufferSize (should be same size as MaxReceivedMessageSize)

· MaxItemsInObjectGraph

For MaxItemsInObjectGraph, a custom behavior is needed, as shown in the following configuration file snippet:

 <bindings>          
    <basicHttpBinding>
        <binding name="BasicHttpBinding_ICampaignManagementService" closeTimeout="00:01:00"
            openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
            allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
            maxBufferSize="6553600" maxBufferPoolSize="524288" maxReceivedMessageSize="6553600"
            messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
            useDefaultWebProxy="true">
            <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                maxBytesPerRead="4096" maxNameTableCharCount="16384" />
            <security mode="Transport">
                <transport clientCredentialType="None" proxyCredentialType="None"
                    realm="" />
                <message clientCredentialType="UserName" algorithmSuite="Default" />
            </security>
        </binding>
       
    </basicHttpBinding>
</bindings>

<client>
    <endpoint address="https://adcenterapi.microsoft.com/Api/Advertiser/V5/CampaignManagement/CampaignManagementService.svc"
        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ICampaignManagementService"
        contract="ICampaignManagementService" name="BasicHttpBinding_ICampaignManagementService"
    behaviorConfiguration="LargeQuotaBehavior"/>           
</client>

<behaviors>
  <endpointBehaviors>
    <behavior name="LargeQuotaBehavior">
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
    </behavior>
  </endpointBehaviors>
</behaviors>
