Hey, I have an array of strings and I want to replace a certain substring in each of those elements. Is there an easy way to do that besides iterating the array explicitly?
Thanks :-)
Ultimately, anything you do is going to do exactly that anyway. A simple for
loop should be fine. There are pretty solutions involving lambdas, such as Array.ConvertAll
/ Enumerable.Select
, but tbh it isn't necessary:
for(int i = 0 ; i < arr.Length ; i++) arr[i] = arr[i].Replace("foo","bar");
(the for
loop has the most efficient handling for arrays ; and foreach
isn't an option due to mutating the iterator variable)
您可以隐式地迭代数组
arrayOfStrings = arrayOfStrings.Select(s => s.Replace("abc", "xyz")).ToArray();
