System.ArgumentNullException在System.Threading.Monitor.Enter [英] System.ArgumentNullException in System.Threading.Monitor.Enter

问题描述

我有一个code是这样的：

I've got a code like this:

我们的一些客户接受System.ArgumentNullException在System.Threading.Monitor.Enter在以下code座的：

Some of our clients receiving "System.ArgumentNullException in System.Threading.Monitor.Enter" in the following code block:

Public Class CheckStuff

   Private Shared SLock As New Object

   Public Sub GetIt()
          Synclock SLock
             DoSomething()
          End Synclock       
   End Sub
End Class

这怎么可能呢？考虑到 SLOCK 是共享的，永远不会从其他地方感动？

How can this be possible? Considering the SLock is shared, never touched from anywhere else?

推荐答案

我的猜测是，你已经简单化样品code - 它必须从别的东西被触动，使之没有。或者，你的锁定方法被调用之前 CheckStuff 完成初始化。堆栈跟踪将是有益的。

My guess is that you've oversimplified your sample code - it must be touched from something else to make it Nothing. Or, your locking method is called before CheckStuff has finished initializing. A stack trace would be helpful.
