C#\ Lock \ Lock实例成员VS Lock静态成员 [英] C# \ Lock \ lock instance member VS lock static member

问题描述

哪个更好?这两个选项在运行时间上有什么区别吗?

what is better? is there any difference in runtime between the two options?

推荐答案

锁定静态对象和锁定实例成员之间没有运行时差异.但是，如果您使用实例锁并正在更新静态代码，则它可能会破坏您的代码.

There is no runtime difference between locking a static and locking an instance member. However, it can break your code if you use an instance lock and are updating a static.

class Broken {
  static int myCounter;
  object synch = new object();

  void SomeMethod()
  {
      lock (synch) { // BAD
        ++myCounter; 
      }
  }
}
