获取Arraylist数据？ [英] Getting Arraylist data?

问题描述

假设我有一个名为 MyArray 的 Arraylist ，其中包含3个计数。



在调试视图中，

MyArray | count = 3

[0] | 价值

[1] | 数= 12

[2] | 1



对于这种类型的arraylist这样就可以了：

ArrayList fromlist =（ArrayList）（（ArrayList）MyArray）[2];



我会得到1.

但是在下面的Arraylist中我怎么能得到？

MyArray | count = 3

+ [0] < b> | something.ReturnObjectClass

+ [0] | something.ReturnObjectClass

+ [0] | something.Return ObjectClass



数据包含在内，如果你点击加号（+）就会找到。

我的问题是如何从Arraylist获取数据显示Return --- ObjectClass而不是数据。

谢谢。

Suppose I have an Arraylist called MyArray which contains 3 counts.

In Debug View,
MyArray|count=3
[0] | "value"
[1] | Count=12
[2] | 1

For this type of arraylist It is OK for like this:
ArrayList fromlist = (ArrayList)((ArrayList)MyArray)[2];

And I will get 1.
But in this following Arraylist how can I get?
MyArray|count=3
+ [0] | something.ReturnObjectClass
+ [0] | something.ReturnObjectClass
+ [0] | something.ReturnObjectClass

The data is contained and will find if you Click plus(+) .
My Question is how to get data from Arraylist which shows Return---ObjectClass instead of it data.
Thanks.

推荐答案

没有。 MyArray [2]是一个数字 - 1 - 不是ArrayList。 MyArray [1]似乎是一个arraylist ...



只是一个建议，但是你要返回或以其他方式传递多个值的ArrayList它可能最好创建特定的类来保存三个值并通过属性访问它们 - 然后你根本不需要抛出它们，并且不可能使用错误的元素！

No. MyArray[2] is a number - 1 - not an ArrayList. MyArray[1] would seem to be an arraylist...

Just a suggestion, but it you are returning or otherwise passing multiple values around with an ArrayList it would probably be a good idea to create specific class to hold the three values and access they via properties - then you don't have to cast them at all, and it is impossible to use the wrong element!
