Something along the line of:

C#

string z = @"20151003,2015-10-03 18:17:36,83556593,1555907159,001,abcde,1,ggg,,,,,,,,,,,,,,,,,,,,,,,,,20151003,2015-10-03 18:17:36,83556593,2555907157,002,sadfgfhg,1,fdghh,,,,,,,,,,,,,,,,,,,,,,,,,20151003,2015-10-03 18:17:36,83556593,3555907157,003,wertre,1,ewr,,,,,,,,,,,,,,,,,,,,,,,,,";
      System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex(@"(\d{8},\d{4}-\d{2}-\d{2})");
      string[] y = reg.Split(z);

Please bear in mind that i'm not a Regex Guru at all... ;)

hope some of its helps

Try below code:

C#

string temp1 = @"20151003,2015-10-03 18:17:36,83556593,1555907159,001,abcde,1,ggg,,,,,,,,,,,,,,,,,,,,,,,,,20151003,2015-10-03 18:17:36,83556593,2555907157,002,sadfgfhg,1,fdghh,,,,,,,,,,,,,,,,,,,,,,,,,20151003,2015-10-03 18:17:36,83556593,3555907157,003,wertre,1,ewr,,,,,,,,,,,,,,,,,,,,,,,,,";

string[] temp = temp1.Split(',');
int total = temp.Length;
int totalIndex = temp.Length;

if (total % 32 == 0)
{
	totalIndex = total / 32;
}
else
{
	totalIndex = (total / 32) +1;
}
string[] tempResult = new string[totalIndex];

for (int idx = 0; idx < totalIndex; idx++)
{
	var tempArr = temp.Select((s, i) => new { i, s })
		   .Where(t => (t.i >= (idx * 32)) && (t.i <= ((idx +1)* 32 - 1)))
		   .Select(t => t.s)
			.ToArray();
	tempResult[idx] = string.Join(",", tempArr);
}

foreach (string t in tempResult)
{
	Console.WriteLine(t.ToString());
}
