splitting a string into 255 chars 1

[jimberger]

Hi,

I have a large string say maybe 1000 chars long and I want to split the string into 250 chars so i will have

str = 1000 chars long

do the split..

str1 = 250 chars long
str2 = 250 chars long
str3 = 250 chars long

etc..

does anyone know how to do this?

thanks for your time

jimberger,
Is there a delimter between characters? If so, what is it?

Ex: "one,two,three" => The comma is the delimter.

Cheers.

hi,

no there isnt a delimeter unfortunately because i could then use the split function.

thanks

You could just get the length of the string and substring it in 250 character chunks. It wouldn't be that difficult of a piece of code to write, for any dynamic string length.

But, there is probably an easier way of doing it, I always seem to pick long and involved ways!

Something like this maybe?

int i = 0;
int index = 0;
int len = srcString.Length;
if (len >= 250)
{
  while (i < len - 250)
  {
    destStrings[index] = srcString.Substring(i, 250);
    i += 250;
    index++;
  }
}
// pick up any remainder
if (len % 250 > 0)
{
   index++;
   destStrings[index] = srcString.Substring(i)
}

Yep, that's what I envisioned. But, when I get these grand schemes in my mind, someone always comes along with a regex or a built in function that would have done the work for me. Oh, well.

Star for your efforts, Chip.

Yeah, the Split method wouldn't help in this case, as you don't have a delimiter to split on. So you have to do it the hard way.

Note that these are characters, not bytes.

Here is what I came up with but I do not like the way it handles the newline \n, or the tab \t. I used 5 just for testing.

using System; 
using System.Text.RegularExpressions; 
namespace regexsplitpattern  
{ 
	class MainClass 
	{	
		public static void Main(string[] args) 
		{ 
			string input = "12a\t3412b3412c3412d3412e341\n2";
			MatchCollection mc;
			Regex regex = new Regex("(.{5}|.+)",RegexOptions.Singleline); 
			mc = regex.Matches(input);
			for (int i = 0; i < mc.Count; i++) 
			{
				Console.WriteLine("value " + mc[i].Value);
			}
		}
	}
}

results
value 12a 3
value 412b3
value 412c3
value 412d3
value 412e3
value 41
2
