TryGet method

Try/Get methods return a boolean and "out" a value. Could be later called without assigning the return value to a variable:

tracker.TryGetRunningVisitorTest(out recordedVisitorTest);

======================================

public override bool TryGetRunningVisitorTest(out TestDefinitionItem test)

        {

            string testId = string.Empty;

            try

            {

                if (!string.IsNullOrEmpty(Tracker.Visitor.Tags[_VisitorTestTagName]))

                {

                    //test for test not being in the web db

                    testId = Tracker.Visitor.Tags[_VisitorTestTagName];

                    Item testItem = Sitecore.Context.Database.GetItem(testId);

                    if (testItem != null)

                    {

                        test = new TestDefinitionItem(testItem);

                       

                        if (test.IsRunning)

                        {

                            return true;

                        }

                    }

                }

            }

            catch (Exception ex)

            {

                Log.Error("Error reading a Visitor Tag " + _VisitorTestTagName, ex, this);

                test = null;

                return false;

            }

            test = null;

            return false;

        }
