Method UnsafePerformLockedOperation

UnsafePerformLockedOperation<TState>(TState, Action<WeakList<T>, TState>)

Runs the specified operation while holding the list's internal lock, so that multiple operations can be performed without other threads modifying the list in between them.

Declaration

public void UnsafePerformLockedOperation<TState>(TState state, Action<WeakList<T>, TState> operation) where TState : allows ref struct

Parameters

Type	Name	Description
TState	state	A state value to pass to the operation.
Action<WeakList<T>, TState>	operation	The operation to run. It receives the list and the state value.

Type Parameters

Name	Description
TState

Remarks

The lock is also required by the finalizer thread to remove nodes whose values have been garbage collected, so holding it for more than a short time delays finalization of every object in the process. Keep operations short. For long-running compound operations, use your own lock and account for nodes being removed from the list concurrently.

Disposing the list from within operation releases the lock immediately, so any code that runs in the operation after the dispose call is no longer protected by it.

Exceptions

Type	Condition
ObjectDisposedException	The list has been disposed.
