问题描述

如何创建简单的类定义数组?

How do I creat a simple array of class definitions?

我想达到的目标的示例;

   Example of what I would like to acheive;

将class(10)视作Class? = {DerivedClassDefA,DerivedClassDefB ...}

   dim classes(10) as Class?? = {DerivedClassDefA,  DerivedClassDefB...}

.

.

将暗物A作为新类(3)

    dim objectA as new classes(3)

.

公共函数newObject(ndx为整数)作为BaseClass

    public function newObject(ndx as integer) as BaseClass

返回类(ndx)

结束功能

希望这个问题能解决,希望有人能帮忙吗?

推荐答案

基本上,您使用从类派生的类型.

Basically you use the type that the classes derive from.

例如,如果您具有以下三个类:

So for instance if you have the following three classes:

MyBaseClass->继承System.Object
DerivedClassA->继承MyBaseClass
DerivedClassB->继承MyBaseClass

MyBaseClass -> Inherits System.Object
DerivedClassA -> Inherits MyBaseClass
DerivedClassB -> Inherits MyBaseClass

然后,您可以创建一个数组,其中包含以下任一派生类:

Then you can create an array that holds either derived class with:

将类别(10)设为MyBaseClass = New MyBaseClass(){DerivedClassA_1,DerivedClassB_1}

Dim classes(10) As MyBaseClass = New MyBaseClass(){DerivedClassA_1, DerivedClassB_1}

如果要放入数组中的对象具有不同的基本类型,请使用System.Object作为数组类型.

If the objects you want to put in the array are of different base types, use System.Object as the array type.
