Converting Int Array to String
From Logic Wiki
Contents
Convert an array of integers to a comma-separated string
if we have
int[] arr = new int[5] {1,2,3,4,5};
and we want this
string => "1,2,3,4,5"
.NET 4
string.Join(",", arr)
.NET earlier
string.Join(",", Array.ConvertAll(arr, x => x.ToString()))
or it can be done by using extension methods like this
public static string ToDelimitedString<T>(this IEnumerable<T> lst, string separator = ", ") { return lst.ToDelimitedString(p => p, separator); }
public static string ToDelimitedString<S, T>(this IEnumerable<S> lst, Func<S, T> selector, string separator = ", ") { return string.Join(separator, lst.Select(selector)); }
So now just:
new int[] { 1, 2, 3, 4, 5 }.ToDelimitedString();
