static member Synchronized : 
        stack:Stack -> Stack

Parameters

stack
Type: System.Collections.Stack

The Stack to synchronize.

Return Value

Type: System.Collections.Stack

A synchronized wrapper around the Stack.

Exception Condition
ArgumentNullException

stack is null.

To guarantee the thread safety of the Stack, all operations must be done through this wrapper.

Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.

The following code example shows how to lock the collection using the SyncRoot during the entire enumeration.

This method is an O(1) operation.

The following example shows how to synchronize a Stack, determine if a Stack is synchronized, and use a synchronized Stack.
