I want to split after 20 characters in a given string and i want to place in another string

Hi
In my applcation for example there are 160 characters or more .... i want to split after 20 characters in next line
if hi karthik is there i want to break after the completion of word.

string str=some 160 characters or more

// and i want to break after 20 characters and iwant to place in another string

plz help me how to split...

If "hi karthik" can only appear at most once in the string, then try this:

using System;

using System.Text;

class Test

{

static void Main()

{

string s = "aaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbhi karthikccccccccccccccccccccdd";

int index = s.IndexOf("hi karthik");

if (index == -1)

{

s = Splitter(s);

}

else

{

string temp = Splitter(s.Substring(0, index));

temp += "\r\nhi karthik";

if (s.Length >= index + 10)

{

string temp2 = Splitter(s.Substring(index + 10));

temp += "\r\n" + temp2;

}

s = temp;

}

Console.WriteLine(s);

Console.ReadKey();

}

static string Splitter(string s)

{

int numLines = s.Length/20;

int remainder = s.Length % 20;

if (remainder > 0) numLines++;

StringBuilder sb = new StringBuilder();

string line = null;

for(int i = 0; i < numLines; i++)

{

if (i < numLines - 1)

{

line = s.Substring(i * 20, 20);

sb.Append(line);

sb.Append("\r\n");

}

else

{

line = s.Substring(i * 20);

sb.Append(line);

}

return sb.ToString();

}
