示例1: Finally_IncompletedTask_ExceptionInFinally
public Task Finally_IncompletedTask_ExceptionInFinally()
{
Exception exception1 = new InvalidOperationException("From source");
Exception exception2 = new InvalidOperationException("FromFinally");
// Like test Finally_CompletedTaskOfFault_ExceptionInFinally, but exercises when the original task doesn't complete synchronously
// Act
Task incompleteTask = new Task(() => { throw exception1; });
Task t = incompleteTask.Finally(() => { throw exception2; });
incompleteTask.Start();
// Assert
return t.ContinueWith(prevTask =>
{
Assert.Equal(t, prevTask);
Assert.True(t.IsFaulted);
Assert.IsType<AggregateException>(t.Exception);
Assert.Equal(1, t.Exception.InnerExceptions.Count);
Assert.Equal(exception2, t.Exception.InnerException);
});
}示例2: Task
public Task Finally_NoInputValue_IncompleteTaskOfSuccess_RunsOnNewThreadAndPostsContinuationToSynchronizationContext()
{
// Arrange
int originalThreadId = Thread.CurrentThread.ManagedThreadId;
int callbackThreadId = Int32.MinValue;
var syncContext = new Mock<SynchronizationContext> { CallBase = true };

// Act
Task resultTask = incompleteTask.Finally(() =>

// Assert
incompleteTask.Start();
return resultTask.ContinueWith(task =>
{
Assert.NotEqual(originalThreadId, callbackThreadId);
syncContext.Verify(sc => sc.Post(It.IsAny<SendOrPostCallback>(), null), Times.Once());
});
}示例3: InvalidOperationException

});
// Assert
incompleteTask.Start();
return resultTask.ContinueWith(task =>
{
var ex = task.Exception; // Observe the exception
Assert.NotEqual(originalThreadId, callbackThreadId);
syncContext.Verify(sc => sc.Post(It.IsAny<SendOrPostCallback>(), null), Times.Once());
});
