Java的“同步”和C＃的“锁定”之间有什么区别吗？

Question

这两个关键字是否具有完全相同的效果，或者我应该注意哪些？

Answer 1

根据这个站点： http ： //en.csharp-online.net/CSharp_FAQ ： _What_is_the_difference_between_CSharp_lock_and_Java_synchronized ，C＃ lock和Java synchronized代码块“语义相同”，而对于方法，Java使用synchronized同时C＃使用属性： [MethodImpl(MethodImplOptions.Synchronized)] 。

Answer 2

One interesting difference not covered in the link posted by Keeg: as far as I'm aware, there's no equivalent method calls in Java for .NET's Monitor.Enter and Monitor.Exit , which the C# lock statement boils down to. That means you can't do the equivalent of Monitor.TryEnter either - although of course the java.util.concurrent.locks package (as of 1.5) has a variety of locks which have more features available.

Answer 3

I java you don't have to worry about locking public types that you own.

In .NET, you have to

Updated: this is for types that you own. Locking on public types that you don't own is bad in any language :)
