Replace all occurences of a string from a string array

Question

I have a string array like:

 string [] items = {\"one\",\"two\",\"three\",\"one\",\"two\",\"one\"};

I would like to replace all ones with z

Answer 1

string[] items = { "one", "two", "three", "one", "two", "one" };

If you want it the index way as you specified:

int n=0;
while (true)
{
n = Array.IndexOf(items, "one", n);
if (n == -1) break;
items[n] = "zero";
}

But LINQ would be better

var lst = from item in items
select item == "one" ? "zero" : item;
