Queue.Clone方法的用法C# [英] Queue.Clone method usage C#

问题描述

我找到了以下解决方案

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'不包含'Clone'的定义，找不到扩展方法'Clone'接受类型为'System.Collections.Generic.Queue'的第一个参数(您是否丢失了?using指令还是程序集引用?)

'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?)

如何使用此功能?

推荐答案

克隆可用于旧的非通用 Queue 类.

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

使用通用队列，您可以执行以下操作:

With generic Queue you can do:

var copy = new Queue<T>(oldQueue)
