这是处理BackGroundWorker的正确方法吗？我不确定在调用.Dispose()之前是否需要删除事件.还在RunWorkerCompleted委托中调用.Dispose()确定吗？

public void RunProcessAsync(DateTime dumpDate)
{
    BackgroundWorker worker = new BackgroundWorker();
    worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted);
    worker.DoWork += new DoWorkEventHandler(worker_DoWork);
    worker.RunWorkerAsync(dumpDate);
}

void worker_DoWork(object sender, DoWorkEventArgs e)
{
    // Do Work here
}

void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    BackgroundWorker worker = sender as BackgroundWorker;
    worker.RunWorkerCompleted -= new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted);
    worker.DoWork -= new DoWorkEventHandler(worker_DoWork);
    worker.Dispose();
}
