Conversion from Int array to string array

int[] intarray = { 1, 2, 3, 4, 5 };
string[] result = intarray.Select(x=>x.ToString()).ToArray();

Here you go:

Linq version:

String.Join(",", new List<int>(array).ConvertAll(i => i.ToString()).ToArray());

Simple one:

string[] stringArray = intArray.Select(i => i.ToString()).ToArray();

Try Array.ConvertAll

int[] myInts = { 1, 2, 3, 4, 5 };

string[] result = Array.ConvertAll(myInts, x=>x.ToString());
