示例1: AddWorkflow
public void AddWorkflow(Workflow workflow)
{
using(var context = new WorkflowContext())
{
context.Workflows.Add(workflow);
context.SaveChanges();
}
}示例2: StartWorkflow
public IList<TrackingRecord> StartWorkflow(int id, Dictionary<string, object> wfParams)
{
string fileLocation = null;
int workflowRunId = 0;
using (var context = new WorkflowContext())
{
fileLocation = context.Workflows.First(c => c.Id == id).FileLocation; // Hier kan een NullReferenceException optreden
var workflowRun = new WorkflowRun()
{
WorkflowId = id,
StartTime = DateTime.Now
};
context.WorkflowRuns.Add(workflowRun);
context.SaveChanges();
workflowRunId = workflowRun.WorkflowRunId;
}
var xamlData = ReadXamlFile(fileLocation);
var tracker = new CustomTrackingParticipant();
var wf = ActivityXamlServices.Load(new StringReader(xamlData), new ActivityXamlServicesSettings { CompileExpressions = true });
AutoResetEvent syncEvent = new AutoResetEvent(false);
WorkflowApplication wfApp = new WorkflowApplication(wf, wfParams);
wfApp.Extensions.Add(tracker);
wfApp.Extensions.Add<TextWriter>(() => new StreamWriter(@"C:/XAML/log.txt"));
// Handle the desired lifecycle events.
Exception exception = null;
wfApp.Completed = (e) => syncEvent.Set();
wfApp.OnUnhandledException += (WorkflowApplicationUnhandledExceptionEventArgs e) =>
{
using (WorkflowContext context = new WorkflowContext())
{
context.Tracks.Add(new Track()
{

});
context.SaveChanges();
}
LogTracks(workflowRunId, tracker);
return UnhandledExceptionAction.Terminate;
};
// Start the workflow.
wfApp.Run();
