使用ToArray()将列表转换为数组

问题描述

我创建了一个名为listItem和以下列表的类:

I've created a class called listItem and the following list:

List<listItem> myList = new List<listItem>();

在代码的某个时刻，我想将其转换为数组，从而使用:

At some point in my code, I want to convert it to an array, thereby using:

listItem[] myArray = myList.ToArray();

不幸的是，这不起作用，并且我收到此错误消息:

Unfortunately, this doesn't work, and I get this error message:

Cannot convert [...] listItem[] to [...] List<listItem>

我试图弄清楚这一点，但是非常失败...

I tried to figure this out, but very unsuccessfully...

提前谢谢.

我的错，我编写的第一行代码确实输入错了！

My bad, the first code line I wrote was indeed mistyped!

实际上，以上所有代码都运行良好.我的错误归因于我的功能:

Actually, all the code above works pretty well. My error was due to the fact that my function:

List<listItem> myFunction()

返回了myArray，因此存在转换问题...现在已修复. :)

returned myArray, hence the conversion problem... It is now fixed. :)

谢谢大家的回答.

推荐答案

这是错误(如Darkshadw和Jon Skeet指出的那样)

This is the error (as pointed out from Darkshadw and Jon Skeet)

listItem myList = new List<listItem>();

您正在将List的值分配给listItem.

You are assigning the value of a List to a listItem.

替换为

List<listItem> myList = new List<listItem>();

创建一个listItem列表.然后

to create a list of listItem. Then

listItem[] myArray = myList.ToArray();

将起作用.
