Extend AuditBehavior

Hi, I need a dynamic behavior in Audit.WCF, That is: one service must to audit to X table, and other service to Y table. I want them to use in a differents attributes, something like this:

public class AuditMainApp : AuditBehaviorAttribute { protected override object CreateBehavior() { (CurrentAuditScope.DataProvider as SqlDataProvider).TableName = "AuditEvent_App"; return base.CreateBehavior(); } }

but the AuditBehaviorAttribute is sealed there is another nice way to do that?

That’s not the way to go. You should not change the tablename of the sql data provider because it will be shared among threads.

You have some ways to accomplish what you want, for example creating a custom data provider that wraps different instances of the sqldataprovider, one for each table.

But since what you’re asking sounds familiar, I will better enhance the SqlDataProvider to allow changing the parameters dynamically. For example, instead of setting a TableName as a string, you could set a TableNameBuilder that is a function of the audit event, so you can for example use the EventType (or whatever you want) to define the table name per event:

    Configuration.Setup().UseSqlServer(config => config
        .TableNameBuilder(ev => ev.EventType)
        ...);

And on your service:

[AuditBehavior(EventType = "AuditEvent_App")]
public class OrderService : IOrderService
{
  ...
}

Will work on this enhancement and let you know.
