安全C#:如何保存指针或引用? [英] Safe C# : how to hold a pointer or a reference ?

问题描述

你好.

有可能吗
持有对象引用
在C#的安全类上下文中，请? :-O :)

Hello.

Would it be possible
to hold an object reference
in the safe class context of C#, please ? :-O :)

public abstract class WizardPage : UserControl
{
    private Wizard wizard;

    public WizardPage(ref Wizard wizardRef)
    {
        wizard = wizardRef; // hmmm... is it just a copy now ? :)
    }

    public abstract void OnBack();
    public abstract void OnActivate();
    public abstract void OnNext();
    ...
}

谢谢！

推荐答案

如果Wizard是一个类(引用类型)，则可以不使用ref就将其传递.

If Wizard is a class (reference type) then you can just pass it without the ref.

private Wizard wizard;

public WizardPage(Wizard wizard)
{
    this.wizard = wizard;
}

谢谢！ :)

理解:-D:

Thank you ! :)

Understood :-D :

{
  object o1 = new object(); // o1 is a reference to an real instance in the memory

  object o2;                // o2 is a empty reference yet

  o2 = o1;                  // o2 is a reference to the same instance
                            // referenced by o1, not a reference to an own instance (!!) 

}
