for (CountLine = 0; CountLine < Convert.ToInt32(txtinput.Text); CountLine++)

make sure your textbox has some numeric value, hope you are failing here.

my code is as follows right now :

{
try
{
string filename = Path.GetFileName(FileUploadControl.FileName);
FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
}
catch (Exception ex)
{
throw;
}
StreamReader Sr = new StreamReader();
string Line = string.Empty; ;
int CountLine = 0;
int countfile = 1;
string[] lines = new string[100];
while ((Line = Sr.ReadLine()) != null)
{
for (CountLine = 0; CountLine < 5; CountLine++)
{
lines[CountLine] = Line;
Line = Sr.ReadLine();
}
string newpath = "C:\\Users\\Anisha\\Desktop\\Split" + countfile + ".txt";
