下面的代码示例演示如何从 ContextStack中删除值。

// Pop each item off the stack.
Object^ item = nullptr;
while ( (item = stack->Pop()) != 0 )
   Console::WriteLine( "Value popped from stack: {0}", item );
// Pop each item off the stack.
object item = null;
while( (item = stack.Pop()) != null )
    Console.WriteLine( "Value popped from stack: "+item.ToString() );
' Pop each item off the stack.        
Dim item As Object = stack.Pop()
While item IsNot Nothing
    Console.WriteLine(("Value popped from stack: " + item.ToString()))
    item = stack.Pop()
End While
