C# string[] to int[] [duplicate]

Answer 1

int[] a = "123,456".Split(’,’).Select(s => int.Parse(s)).ToArray();

Answer 2

This linq query should do it:

strArray.Select(s => int.Parse(s)).ToArray()

Answer 3

”123,456”.Split(’,’).Select( s => int.Parse(s) ).ToArray();

Answer 4

Use this :

"123,456".Split(',').Select(s => int.Parse(s)).ToArray()

Answer 5

Here is the extension method. This is done on string, because you can't add a static function to a string.

public static int[] ToIntArray(this string value)
{
    return value.Split(',')
        .Select<string, int>(s => int.Parse(s))
        .ToArray<int>();
}

Here is how you use it

string testValue = "123, 456,789";

int[] testArray = testValue.ToIntArray();

This assumes you want to split on ',' if not then you have to change the ToIntArray

Answer 6

I think, like that:

string[] sArr = { "1", "2", "3", "4" };
int[] res = sArr.Select(s => int.Parse(s)).ToArray();
