Queues the specified delegate to the thread pool, but does not propagate the calling stack to the worker thread.
Assembly: mscorlib (in mscorlib.dll)
'Declaration Public Shared Function UnsafeQueueUserWorkItem ( _ callBack As WaitCallback, _ state As Object _ ) As Boolean
- Type: System.Threading.WaitCallback
A WaitCallback that represents the delegate to invoke when a thread in the thread pool picks up the work item.
- Type: System.Object
The object that is passed to the delegate when serviced from the thread pool.
Unlike the QueueUserWorkItem method, does not propagate the calling stack to the worker thread. This allows code to lose the calling stack and thereby to elevate its security privileges.
Using could inadvertently open up a security hole. Code access security bases its permission checks on the permissions of all the callers on the stack. When work is queued on a thread pool thread using , the stack of the thread pool thread will not have the context of the actual callers. Malicious code might be able exploit this to avoid permission checks.
Requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
