Split string two by two and append to list

I have string like this:

string mystring = "123456"

And I want to split two by two to 12 34 56.

Pseudocode:

var list = new List<int>();
foreach(var e in something){
    string mystring ="123456";
    var split = ...
    // convert the splitted string
    list.Add(convertedString);
}

How I can do this?

You can try this,

var str = "123456";
var intList = Enumerable.Range(0, str.Length / 2)
            .Select(i => Convert.ToInt32( string.Concat(str.Skip(i * 2).Take(2)))).ToList();

if you console log the result: 

foreach(var e in intList)
{
   Console.WriteLine(e);
}

Output list will contain elements like `12, 34, 56 respectively.`

Another way which may or may not be easier to understand

public static IEnumerable<int> SplitInts(this string source)
{
    for (var i = 0; i < source.Length; i += 2)
        yield return int.Parse(source.Substring(i, Math.Min(2, source.Length - i)));
}

Usage

var test = "23456";
foreach (var item in test.SplitInts())
    Console.WriteLine(item);

Output

23
45
6
