Converting VB to C# (Arrays)

Question

I'm not very familiar with VB.net at the moment and having some trouble converting the following code to C#.

Dim itemList As New ArrayList
Dim strMyitemList(itemList.Count - 1) As String

        For x = 0 To (itemList.Count - 1)
            strMyitemList(x) = itemList(x)
        Next

So far I've got:

ArrayList itemList = new ArrayList();
string[] strMyitemList = new string[itemList.Count -1];

            for (int x = 0; x <= (itemList.Count - 1); x++)
            {
                strMyitemList[x] = itemList(x);
            }

I'm getting the error CS0149 "Method name expected" on "itemList(x)".

Thanks

If you're not familiar with vb.net, what prevents you from writing working C# code? — user202729

@user202729 I am required to convert something that already exists to C# from VB.net. However, was trying to understand the VB to convert it. — andtodd

change strMyitemList[x] = itemList(x); to strMyitemList[x] = itemList[x]; — Shilpa

In C# you shouldn't use itemList.Count - 1 when declaring the array. It is only used in VB.NET because it handles arrays differently. — Visual Vincent

itemList is an ArrayList which has an indexer. In C# you use them with []:

strMyitemList[x] = (string)itemList[x];

But nowadays there is no reason to use ArrayList. Use a strongly typed List<string>:

strMyitemList[x] = itemList[x];

Thanks Tim, I noticed I'd added the square brackets to strMyitemList but not itemList (also forgot the cast).
