使用 BAM API 載入 BAM 攔截器
本主題會針對從程式碼 (而不是從組態檔案) 載入 WF 和 WCF 攔截器提供相關資訊。
從程式碼載入 WF 攔截器
若要從程式碼載入 WF 攔截器，您必須建立新的 WorkflowRuntime 執行個體，並使用新的 BamTrackingService 執行個體來呼叫 AddService 方法。 這項作業示範如下：
string connectionString = "Integrated Security=SSPI;Data Source=.;Initial Catalog=BAMPrimaryImport";
int PollingIntervalSec = 300;
WorkflowRuntime workflowRuntime = new WorkflowRuntime();
workflowRuntime.AddService(new BamTrackingService(connectionString, interceptorConfigurationPollingInterval));
從程式碼載入 WCF 攔截器
若要載入 WCF 攔截器，您必須建立可開啟此服務並供您的實作存取的衍生類別。 這項作業示範如下：
// Your project must have a reference to Microsoft.BizTalk.BAM.Interceptors.dll.
// Create a derived class accessible to the implementation that opens the service.
internal class MyBamBehaviorExtension : BamBehaviorExtension
{
internal MyBamBehaviorExtension(string connectionString, int pollingInterval)
: base()
{
this.ConnectionString = connectionString;
this.PollingIntervalSec = pollingInterval.ToString();
}
internal IEndpointBehavior Create()
{
return (IEndpointBehavior) this.CreateBehavior();
}
}
// Add the endpoint behavior just before the service is opened.
// In this example the connection string and polling intervals are being read from appSettings in App.config.
MyBamBehaviorExtension bamBehaviorExtension = new MyBamBehaviorExtension(ConfigurationManager.AppSettings["ConnectionString"], int.Parse(ConfigurationManager.AppSettings["PollingIntervalSec"]));
IEndpointBehavior bamBehavior = bamBehaviorExtension.Create();
foreach (System.ServiceModel.Description.ServiceEndpoint endpoint in myServiceHost.Description.Endpoints)
{
if (endpoint.Behaviors.Find<MyBamBehaviorExtension>() == null)
endpoint.Behaviors.Add(bamBehavior);
}
