how to add a space after each four character in string

is there any way to do that ...

adding something something ( actually space ) after some number of chars in string (actually after four chars in a string)

.NET Development12

There is not any native method that will let you do that, but the following code should work:

using System;< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

string x = "abcd";

string y = AddSpaceAtInterval(x, 3);

}

static string AddSpaceAtInterval(string originalString, int interval)

{

if (interval == 0 || (originalString.Length <= interval))

{

return originalString;

}

string newString = String.Empty;

int currentIndex = 0;

for (int i = 0; i < originalString.Length / interval; ++i)

{

newString += originalString.Substring(currentIndex, interval) + " ";

currentIndex += interval;

}

if (currentIndex != originalString.Length)

{

newString += originalString.Substring(currentIndex, originalString.Length - currentIndex);

}

return newString;

}

If your string is very long or you are going to call this function many times then you may want to use a StringBuilder for better memory perofrmance.

Mark.

Here another simple method for you

private string StringModifier(string InputString, int Interval, string InsertString)
{
int i = 1;
int j = 0;

while (true)
{
int NextPos = ((i++) * Interval) + (j++);
if (NextPos > InputString.Length)
break;
else
InputString = InputString.Insert(NextPos, InsertString);
}

return InputString;
}

//Call like this
string MyString = StringModifier("thisthisthisthisthisthisthisthis", 4, " ");

Childs play for Regular Expressions see code. Change the 4 in the expression for a different value say to 6 to characters.

using System.Text.RegularExpressions;

public static void AddSpaceAfterFour()
{
string text = "Thisworkwantdocscode1234*&%$";

}

Console OutputThis work want docs code 1234 *&%$
