我想知道执行我的异步任务需要多长时间,以便我可以改进执行时间。
请看测试方法并指教。测试背景:我想在给定 sAMACcountName 的情况下从 Active Directory 中找出用户帐户管理员。
[TestMethod]
public async Task GetManagerAsync_TestMethod()
{
// connect to the Active Directory
var serviceUsers = new User(@"LDAP://XXXXXXXXX", @"USER", "PASSWORD");
// get the time before the start of operation
var sTime = DateTime.Now;
// perform the task
var task = await serviceUsers.GetManagerAsync(@"sAMAccountName");
// get the time after the operation
var eTime = DateTime.Now;
// get the time span between the start and end time
TimeSpan taskRunTime = eTime - sTime;
System.Diagnostics.Debug.WriteLine("Operation took {0} seconds", taskRunTime.TotalSeconds);
Assert.IsNotNull(task);
}
最佳答案
你应该使用 Stopwatch
相反。
var stopwatch = Stopwatch.StartNew();
var task = await serviceUsers.GetManagerAsync(@"sAMAccountName");
stopwatch.Stop();
var elapsed = stopwatch.Elapsed;
它不仅在语义上更正确,而且更准确:
If the installed hardware and operating system support a high-resolution performance counter, then the Stopwatch class uses that counter to measure elapsed time. Otherwise, the Stopwatch class uses the system timer to measure elapsed time.
