如何将对象/结构转换为arraylist? [英] How to cast object/structure into arraylist?

问题描述

我在C#.net中有一个结构.我已经创建了该结构的对象.我需要将此结构对象转换为ArrayList.我正在使用:

I have a structure in C#.net. I have created an object of that structure. I need to cast this object of structure into ArrayList. I am using :

OrderMessageStructure.OrderMessage orderToModify = new OrderMessageStructure.OrderMessage();

object neworderobject = (object)orderToModify;
ArrayList arr = new ArrayList();
arr = (ArrayList)neworderobject;

但是我收到错误消息无法将类型为'OrderMessage'的对象转换为类型为'System.Collections.ArrayList'."

But I am getting error "Unable to cast object of type 'OrderMessage' to type 'System.Collections.ArrayList'."

推荐答案

您的问题没有足够的信息来给出肯定的答案.

Your question doesn't have quite enough information to give a sure answer.

如果要创建OrderMessage对象的ArrayList，则需要先创建数组列表，然后创建OrderMessage的ADD实例.

If you want to make an ArrayList of OrderMessage objects then you need to create the arraylist FIRST and then ADD instances of OrderMessage.

如果要使用OrderMessage的强类型ArrayList，请使用通用命名空间中的List和OrderMessage的ADD实例.

If you want a strongly typed ArrayList of OrderMessage then use List from the Generic Namespace and ADD instances of OrderMessage to it.

如果OrderMessage中具有数组结构，则需要向其添加一个返回数组列表的方法.您将必须编写将OrderMessage转换为ArrayList的代码.

If your OrderMessage has an array structure in it then you will need to add a method to it that returns an arraylist. You will have to write the code converting the OrderMessage to an ArrayList.
