Although it probably won't execute as quickly as the conventional approach, here's a concise way to do the same thing using regular expressions:

using System;
using System.Text.RegularExpressions;

class Test
{
static void Main()
{
string s = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
s = Regex.Replace(s, ".{30}", "$0\r\n");
s = s.TrimEnd('\r', '\n'); // remove a trailing \r\n if there is one
Console.WriteLine(s);
Console.ReadKey();
}
}

This should do it:

using System;

class Test
{
static void Main()
{
string s = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
int len = s.Length / 30;
int rem = s.Length % 30;
if (rem > 0) len++;
string[] lines = new string[len];

int j = 0;

for(int i = 0; i < s.Length; i += 30)
{
if (i + 30 < s.Length)
{
lines[j] = s.Substring(i, 30);
j++;
}
else
{
lines[j] = s.Substring(i);
}
}

s = String.Join("\r\n", lines);
Console.WriteLine(s);
Console.ReadKey();
}
}
