C#使用子线程回调阻止呼叫挂起

connection = new OdbcConnection(connectionString);
connection.Open();

不幸的是,在这个非常具体的情况下,挂起是我无法控制的.

所以我希望能够处理这种情况,至少抛出异常.

我想旋转一个子线程,它会在超时时回调主线程.

你会怎么做 – 这是我的尝试：

OdbcConnection connection = null;

var timeout = TimeSpan.FromSeconds(15);
var resetEvent = new ManualResetEvent(false);
bool exceptionThrown = false;

var connectionThread = new Thread(() =>
{
    try
    {
        connection = new OdbcConnection(connectionString);
        connection.Open();
    }
    catch(Exception e)
    {
        exceptionThrown = true;
    }
    finally
    {
        resetEvent.Set();
    }
});

connectionThread.Start();

var isOk = resetEvent.WaitOne(timeout);

if(exceptionThrown)
{
   throw now Exception("Exception connection to DB");
}

if (!isOk)
{
    connectionThread.Abort();
    const string messageFormat = "Timeout of {0} reached while creating OdbcConnection to {1}.";
    throw now Exception(string.Format(messageFormat,timeout,connectionString));
}

更新：
这是我尝试使用任务：

OdbcConnection connection = null;
var connectionTask = Task.Factory.StartNew(() =>
{
    connection = new OdbcConnection(connectionString);
    connection.Open();
    Thread.Sleep(3000);
});
try
{
    connectionTask.Wait(1000);       // Wait for 1 second.
}
catch (AggregateException ex)
{
    Console.WriteLine("Exception in connection");
}

bool completed = connectionTask.IsCompleted;
if(!completed)
{
    Console.WriteLine("Connection Timed-out");
}
else
{
    connection.DoSomething();
}
