Gets a value that indicates the recursion policy for the current ReaderWriterLockSlim object.
Assembly: System.Core (in System.Core.dll)
Property Value
Type: System.Threading.LockRecursionPolicyOne 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.

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.
