从 Int 数组到字符串数组的转换

Question

When I am converting array of integers to array of string, I am doing it in a lengthier way using a for loop, like mentioned in sample code below. Is there a shorthand for this?

The existing question and answers in SO are about int[] to string (not string[] ). So they weren't helpful.

While I found this Converting an int array to a String array answer but the platform is Java not C#. Same method can't be implemented!

        int[] intarray =  { 198, 200, 354, 14, 540 };
        Array.Sort(intarray);
        string[] stringarray = { string.Empty, string.Empty, string.Empty, string.Empty, string.Empty};

        for (int i = 0; i < intarray.Length; i++)
        {
            stringarray[i] = intarray[i].ToString();
        }

Answer 1

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

Answer 2

Try Array.ConvertAll

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

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

Answer 3

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();

Answer 4

I need the same thing as mentioned:

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

but for multidimensinal array. Let's say I have

int[,] intArray = new int[4, 4];

and I want to pass it to a function that requires string multidimensional array, so I want to convert it to string when I call that function.
