示例1: Example
' 導入命名空間
Imports System.Threading
Class Example
' By default, the lock recursion policy for a new
' ReaderWriterLockSlim does not allow recursion.
Private Shared rwls As New ReaderWriterLockSlim()
Shared Sub ThreadProc()
Console.WriteLine("Acquire the reader lock.")
rwls.EnterReadLock()
Try
Console.WriteLine(vbCrLf & _
"Attempt to acquire the reader lock recursively:")
rwls.EnterReadLock()
Catch lre As LockRecursionException
Console.WriteLine("{0}: {1}", _
lre.GetType().Name, lre.Message)
End Try
Try
Console.WriteLine(vbCrLf & _
"Attempt to acquire the writer lock recursively:")
rwls.EnterWriteLock()
Catch lre As LockRecursionException
Console.WriteLine("{0}: {1}", _
lre.GetType().Name, lre.Message)
End Try
End Sub
Shared Sub Main()
Dim t As New Thread(AddressOf ThreadProc)
t.Start()
t.Join()
End Sub
End Class輸出：
Acquire the reader lock. Attempt to acquire the reader lock recursively: LockRecursionException: Recursive read lock acquisitions not allowed in this mode. Attempt to acquire the writer lock recursively: LockRecursionException: Write lock may not be acquired with read lock held. This pattern is prone to deadlocks. Consider using the upgrade lock.
