Os valores possíveis são "None" e "GZip".The possible values are "None" and "GZip". O padrão é "None".The default is "None".

Exemplos

O exemplo de código a seguir demonstra como usar InstanceEncodingOption em um SqlWorkflowInstanceStore .The following code sample demonstrates using InstanceEncodingOption in a SqlWorkflowInstanceStore. Este exemplo é do exemplo de configuração interna .This example is from the Built-in Configuration sample.

static void Main(string[] args)
{
    // Create service host.
    WorkflowServiceHost host = new WorkflowServiceHost(new CountingWorkflow(), new Uri(hostBaseAddress));

    // Add service endpoint.
    host.AddServiceEndpoint("ICountingWorkflow", new BasicHttpBinding(), "");

    // Define SqlWorkflowInstanceStoreBehavior:
    //   Set interval to renew instance lock to 5 seconds.
    //   Set interval to check for runnable instances to 2 seconds.
    //   Instance Store does not keep instances after it is completed.
    //   Select exponential back-off algorithm when retrying to load a locked instance.
    //   Instance state information is compressed using the GZip compressing algorithm.
    SqlWorkflowInstanceStoreBehavior instanceStoreBehavior = new SqlWorkflowInstanceStoreBehavior(connectionString);
    instanceStoreBehavior.HostLockRenewalPeriod = new TimeSpan(0, 0, 5);
    instanceStoreBehavior.RunnableInstancesDetectionPeriod = new TimeSpan(0, 0, 2);
    instanceStoreBehavior.InstanceCompletionAction = InstanceCompletionAction.DeleteAll;
    instanceStoreBehavior.InstanceLockedExceptionAction = InstanceLockedExceptionAction.AggressiveRetry;
    instanceStoreBehavior.InstanceEncodingOption = InstanceEncodingOption.GZip;
    host.Description.Behaviors.Add(instanceStoreBehavior);

    // Open service host.
    host.Open();

    // Create a client that sends a message to create an instance of the workflow.
    ICountingWorkflow client = ChannelFactory<ICountingWorkflow>.CreateChannel(new BasicHttpBinding(), new EndpointAddress(hostBaseAddress));
    client.start();

    Console.WriteLine("(Press [Enter] at any time to terminate host)");
    Console.ReadLine();
    host.Close();
}

Comentários

Se o valor for definido como "GZip", os dados da instância serão compactados usando o algoritmo GZip.If the value is set to "GZip", the instance data is compressed using the GZip algorithm.
