How to get the string array of all keys from the dictionary and modify every string in the same way

Question

Easy and simple (but not very nice) way is just to get the array of the keys and iterate it updating every string.

string[] mapKeys = myDictionary.Keys.ToArray();

    for (int i = 0; i < mapKeys.Length; i++)
        mapKeys [i] = mapKeys [i].Replace("substringToRemove", "");

But is there any way to do it in 1 line of code (e.g. using LINQ)?

Answer 1

mapKeys = mapKeys.Select(o=>o.Replace("substringToRemove", string.Empty)).ToArray();

or from your myDictionary:

string[] mapKeys = myDictionary.Keys.Select(o=>o.Replace("substringToRemove", string.Empty)).ToArray();
