Why use try {} finally {} with an empty try block?




在逐步执行MS .NET代码时，我偶然发现了以下内容：

try { } finally 
{
  // Called in a finally because it needs to run uninterrupted in order to maintain consistency.
  queued = IOThreadScheduler.current.ScheduleCallbackHelper(callback, state);
}

有趣的把戏。谁能捐赠一个解释？

Answer 1

这很可能旨在在ThreadAbortException存在的情况下执行该行。

根据docs：


  引发此异常时，运行时将在结束线程之前执行所有的finally块。
