Add separator to string at every N characters?

Question

I have a string which contains binary digits. How to separate string after each 8 digit?

Suppose the string is:

string x = \"111111110000000011111111

I am more than late with my answer but you can use this one:

    static string PutLineBreak(string str, int split)
    {
        for (int a = 1; a <= str.Length; a++)
        {
            if (a % split == 0)
                str = str.Insert(a, "\n");
        }

        return str;
    }
