如何从另一个类访问非静态属性 [英] How to access a non-static property from another class

问题描述

我在非静态 MainForm 类中有一个非静态属性:

I have a non-static property inside a non-static MainForm class:

public string SelectedProfile
{
    get { return (string)cbxProfiles.SelectedItem; }
    set { cbxProfiles.SelectedItem = value; }
}

我想从另一个非静态类获取此属性的值.使用 MainForm.SelectedProfile 会出现错误，提示非静态字段、方法或属性需要对象引用".

I would like to get the value of this property, from another non-static class. Using MainForm.SelectedProfile gives an error saying "An object reference is required for the non-static field, method or property".

通常我会通过将 SelectedProfile 设为静态来解决这个问题，但我不能，因为无法将 cbxProfiles(一个 ComboBox 控件)设为静态.

Usually I would solve this problem by making SelectedProfile static, but I can't, since cbxProfiles (a ComboBox control) can't be made static.

那么如何在不使其静态的情况下访问属性的值?

So how do I access the property's value without making it static?

推荐答案

您访问非静态成员的方式与总是相同:通过使用对对象实例的引用.

You access non-static members the same way you always do: by using a reference to an instance of the object.

因此，无论您希望能够使用该属性的代码是什么，您都需要向它传递一个对 MainForm 对象的引用.

So whatever code you want to be able to use that property, you need to pass it a reference to a MainForm object.
