Question

在课堂上锁定的课堂之间有何区别?

例如:

private readonly object xmpp = new object();

lock (xmpp)
{
    ...
}

v

lock (typeof(Xmpp))
{
    ...
}

Answer 1

锁在私人锁定物体上:

 public class X
 {
      private readonly Object _lock = new Object();

      // ...
            lock (_lock)
            {
            }

如果您must同步访问等静态成员,则使用相同的模式:

 public class X
 {
      private readonly static Object s_lock = new Object();
