Hi An instance member is not guaranteed to be thread safe. To guarantee thread safety during enumeration you can lock the collection during the entire enumeration. To allow the collection to be accessed by multiple threads for reading and writing you must implement your own synchronization You refer this link http://msdn.microsoft.com/en-us/magazine/ee412257.aspx You can try the ConcurrentQueue(Of T). Here is a link http://msdn.microsoft.com/en-us/library/dd267265.aspx H ope this helps Thank you

If multiple threads can access a Queue or Queue simultaneously then you need to use the lock statement when calling both the Enqueue and Dequeue methods. Only reading the queue (i.e. the Peek method) is threadsafe and even then you have to ensure the Queue is not modified in the meantime.
