示例1: GetUriInParallelTest
public void GetUriInParallelTest()
{
// arrange
var request = new BasicRequest("http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png", new[] {"a", "b", "c"});
var tileInfo = new TileInfo {Index = new TileIndex(3, 4, "5")};
var urls = new ConcurrentBag<Uri>(); // List is not thread save
// act
var requests = new List<Func<Uri>>();
for (var i = 0; i < 100; i++) requests.Add(() => request.GetUri(tileInfo));
Parallel.ForEach(requests, r => urls.Add(r()));
// assert
Assert.True(urls.FirstOrDefault(u => u.ToString() == "http://b.tile.openstreetmap.org/5/3/4.png") != null);
