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?
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
