我想要一些非常简单的东西
// increment counter
Interlocked.Increment(ref _counter);
// automatically decrement counter after 1 sec
Timer timer = new Timer((o) => {
Interlocked.Decrement(ref _counter);
(o as Timer).Dispose();
},timer,1000,Timeout.Infinite);
但是,此代码不可编译
Use of unassigned local variable ‘timer’
有什么简单的方法来修复它吗？它必须是Threading.Timer.
P.S.：我不确定我是否必须调用Dispose,它显然是非托管资源,它是IDisposable,仍然在msdn他们警告
As long as you are using a Timer,you must keep a reference to it. As with any managed object,a Timer is subject to garbage collection when there are no references to it. The fact that a Timer is still active does not prevent it from being collected.
我实际上希望它被收集(自动处理？).那么,处置还是不处置？
