将对象作为副本传递 [英] pass an object as a copy

问题描述

我有如下情况

I have a case as follows

class nurses
{
...
...
}
class shifts
{
nurses _nurses;
shifts(nurses _nurses)
{
this._nurses=_nurses;// here the reference of nurses is assigned not the value.
}
...
...
}
main()
{
var ns=new nurses();
var shfts= new shifts(ns);//I want to pass the ns as copy so the value of ns is not changed after shifts make changes on its copy.


}

请提出一些快速解决方案.这让我感到困惑.
谢谢

Please suggest some quick solution. It is confusing to me.
Thank you

推荐答案

您可以将nurses定义为struct，使其成为值类型:

或者您可以在nurses上实现IClonable来创建副本:

You can either define nurses as a struct, making it a value type:

or you can implement IClonable on nurses to create a copy:
