c# string array reference

Question

I'm new to c# but struggling with some fairly basic assignments.

This works:

ListViewItem item = new ListViewItem(new[] { "1", "2", "3", "4" });

This Does not:

string[] rrr = new string[4]{ "1", "2", "3", "4" };
ListViewItem item = new ListViewItem(new[] rrr);

My Final goal is:

for (int i=0; i<10; i++)
{
    rrr[i] = "SomeText";
}
ListViewItem item = new ListViewItem(new[] rrr);

Apologies for the basic question, I've not been able to find the right keywords to get a solution. I'm more used to VBA which allows me to get away with anything.....

Thanks

What do you expect new[] rrr to do? I suspect you just want new ListViewItem(rrr) — Jon Skeet

VBA allows you to write and run anything. It does not stop the code from not working. — Aron

I actually suspect he wants new ListViewItem(Enumerable.Range(1, i).ToArray()) or new ListViewItem(Enumerable.Repeat("SomeText", i).ToArray()) — Aron

Welcome on StackOverflow. You could have mentioned that this doesn't compile and which line which does not compile. — Thomas Weller

You should do only this

string[] rrr = new string[4]{ "1", "2", "3", "4" };
ListViewItem item = new ListViewItem(rrr);

so:

for (int i=0; i<10; i++)
{
    rrr[i] = "SomeText";
}
ListViewItem item = new ListViewItem(rrr);

Instead of ListViewItem item = new ListViewItem(new[] rrr); use ListViewItem item = new ListViewItem(rrr);
