多种类型的VB.NET字典 [英] VB.NET dictionary of multiple types

问题描述

我对 VB.NET 非常陌生，而且我有 Objective-C 背景.

I am very new to VB.NET, and I come from an Objective-C background.

在 Objective-C 中，我可以创建一个 NSMutableDictionary 来保存任何类型的值.

In Objective-C, I could create an NSMutableDictionary which could hold any types of values.

在这里使用 VB.NET，我设法制作了一个 Dictionary，但是当我初始化它的一个实例时，我被要求提供一个特定的值类型.如何在一个字典中启用任何值类型?

Here with VB.NET, I managed to make a Dictionary, but when I initialized an instance of it, I am asked for a specific value type. How can I enable any value types within one single dictionary?

推荐答案

你可以写一个字典来保存这样的对象:

You can write a dictionary to hold objects like this:

Dim myDictionary As New Dictionary(Of String, Object)

然后提供它:

myDictionary.Add("keyA", New Button)
myDictionary.Add("keyB", "Test")

这可能不被认为是最佳编程实践.最好利用泛型并让字典保存项目的公共类或接口.

This is probably not considered best programming practice. It's better to take advantage of generics and have a dictionary hold a common class or interface of items.

为每个项目的类或接口使用多个字典会更高效且更易于维护.

Having multiple dictionaries for each class or interface of items would be more efficient and easier to maintain.
