示例1: InternalExecute
sealed internal override void InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager)
{
// first set up an async context
AsyncOperationContext asyncContext = executor.SetupAsyncOperationBlock(instance);
instance.IncrementBusyCount();
AsyncCodeActivityContext context = new AsyncCodeActivityContext(asyncContext, instance, executor);
bool success = false;
try
{
IAsyncResult result = BeginExecute(context, AsyncCodeActivity.OnExecuteComplete, asyncContext);
