如何将WorkItemCollection转换为List

Question

我想将WorkItemCollection转换为List<WorkItem>，以便我可以将其进一步转换为dictionary。这是迄今为止的代码：

var testItemCollectionList = new List<WorkItem>();
WorkItemCollection testItemCollection;
Query query = new Query(project.Store, "Select [Title] From WorkItems", testResults.Select(item => item.TargetId).ToArray());
var car = query.BeginQuery();
testItemCollection = query.EndQuery(car);
testItemCollectionList = ???;
var testItemMapQuery = testItemCollectionList.ToDictionary(w => w, createItemFromQuery);

Answer 1

由于WorkItemCollection通过IEnumerable实施ReadOnlyList，您应该可以使用.Cast<WorkItem>()，然后直接转换为Dictionary。

var testItemMapQuery = testItemCollection.Cast<WorkItem>()
                                         .ToDictionary(w => w, createItemFromQuery);

Answer 2

testItemCollectionList = (from WorkItem mItem in testItemCollection select mItem).ToList();
