Converting a list to an array with ToArray()

Question

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

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

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

listItem[] myArray = myList.ToArray();

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

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

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

Thanks in advance.

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

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

List<listItem> myFunction()

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

Thank you all for your answers.

A listitem isn't the same as a list<> ;) – Moulin

Your first line won't compile to start with, and the error message suggests a conversion the other way round. Please show a short but complete program demonstrating the problem, and the verbatim error message. – Mader

Is that typed in correctly? Your issue seems to have nothing to do with the ToArray() call. – Eme

The error message you've posted relates to converting array of ListItems into List<ListItem>, not the other way around. List<ListItem>.ToArray() should work perfectly fine. Post whole code or whole error message. – Microgamete

Answer 1

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

listItem myList = new List<listItem>();

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

Replace it with

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

to create a list of listItem. Then

listItem[] myArray = myList.ToArray();

will work.

How to give size? – Conciliate

To get size: myArray.size. To set: myArray = new Array[5]; but deletes old array – Blossom

It works. ToArray() on a List converts the list to array depending on the type. Thanks. – Chemaram

Answer 2

have you tried

listItem[] myArray = myList.ToArray(new listItem[]{});

in Java it works, im not sure in c#

Answer 3

string[] s = myList.ToArray();

Considering myList is list of string
