How do I replace an item in a string array?

Question

Using C# how do I replace an item text in a string array if I don\'t know the position?

My array is [berlin, london, paris] how do I replace paris with new york?

Answer 1

You could also do it like this:

arr = arr.Select(s => s.Replace("paris", "new york")).ToArray();

Answer 2

You need to address it by index:

arr[2] = "new york";

Since you say you don't know the position, you can use Array.IndexOf to find it:

arr[Array.IndexOf(arr, "paris")] = "new york";  // ignoring error handling
