Question

Supposed i have an array int[] arr = {1,2,3,4}

I want to convert it into a string.
The result i want it to be like this string a = “1,2,3,4”;

so can i have something “string a = arr….” to do it, instead of writing a for loop??

Thanks

Answer 1

string result = string.Join(", ", arr.Select(item => item.ToString()).ToArray());
