ReaderWriterLockSlim.RecursionPolicy Property

 

Gets a value that indicates the recursion policy for the current ReaderWriterLockSlim object.

Namespace:   System.Threading
Assembly:  System.Core (in System.Core.dll)

public LockRecursionPolicy RecursionPolicy { get; }

Property Value

Type: System.Threading.LockRecursionPolicy

One of the enumeration values that specifies the lock recursion policy.

Recursion policy determines the restrictions on threads that enter the lock more than once. For example, if a lock was created with LockRecursionPolicy.NoRecursion and a thread has entered the lock in read mode, LockRecursionException is thrown if the thread tries to reenter the lock in read mode.

System_CAPS_noteNote

A thread in upgradeable mode can upgrade to write mode or downgrade to read mode regardless of the lock recursion policy setting.

Regardless of recursion policy, a thread that initially entered read mode is not allowed to upgrade to upgradeable mode or write mode, because that pattern creates a strong probability of deadlocks.

For more information about recursion policy and its effects, see the LockRecursionPolicy enumeration and the ReaderWriterLockSlim class.
