Queue.Clone method usage C#

问题

I have found the following solutions Clone function in the documentation on MSDN for the Queue class. But in my code, i get the following error:

private Queue<int> myQueue = new Queue<int>();
var clone = myQueue.Clone();

'System.Collections.Generic.Queue' does not contain a definition for 'Clone' and no extension method 'Clone' accepting a first argument of type 'System.Collections.Generic.Queue' could be found (are you missing a using directive or an assembly reference?)

How can I use this function?

回答1:

Clone is available for old, non-generic Queue class.

With generic Queue you can do:

var copy = new Queue<T>(oldQueue)

回答2:

You are confusing two different types: System.Collections.Queue and System.Collections.Generic.Queue<T>

The second one (which you are using) doesn't have a Clone method.
