SpinLock.TryEnter Method (Boolean)

.NET Framework (current version)
 

Attempts to acquire the lock in a reliable manner, such that even if an exception occurs within the method call, lockTaken can be examined reliably to determine whether the lock was acquired.

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

public void TryEnter(
	ref bool lockTaken
)

Parameters

lockTaken
Type: System.Boolean

True if the lock is acquired; otherwise, false. lockTaken must be initialized to false prior to calling this method.

Exception Condition
ArgumentException

The lockTaken argument must be initialized to false prior to calling TryEnter.

LockRecursionException

Thread ownership tracking is enabled, and the current thread has already acquired this lock.

Unlike Enter, TryEnter will not block waiting for the lock to be available. If the lock is not available when TryEnter is called, it will return immediately without any further spinning.
