Why not simply loop the characters? Something like

C#

string a="1234567890";
string b= "";
string c = "";

for (int counter = 0; counter < a.Length; counter++) {
   if (counter % 2 == 0) {
      b += a.ToArray()[counter];
   } else {
      c += a.ToArray()[counter];
   }
}

Of course it would be better to use a stringbuilder and to convert the original string to an array only once and so on, but to get the idea...

Solution 2

A simple iteration could do the job:

C#

static void mysplit(string input, out string even, out string odd)
{
  even = odd = string.Empty;
  for (int n = 0; n < input.Length; ++n)
  {
    if (n % 2 == 0)
      even += input[n];
    else
      odd += input[n];
  }
}
