String.ToCharArray Method

Copies the characters in this instance to a Unicode character array.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public char[] ToCharArray()

Return Value

Type: System.Char[]
A Unicode character array whose elements are the individual characters of this instance. If this instance is an empty string, the returned array is empty and has a zero length.

The following example demonstrates how to easily create a Unicode character array from a String. The array is then used with the Split method.

using System;

public class StringSplit2 
{
   public static void Main() 
   {
      string delimStr = " ,.:";
	   char [] delimiter = delimStr.ToCharArray();
      string words = "one two,three:four.";
      string [] split = null;

	   Console.WriteLine("The delimiters are -{0}-", delimStr);
	   for (int x = 1; x <= 5; x++) 
      {
	      split = words.Split(delimiter, x);
         Console.WriteLine("\ncount = {0,2} ..............", x);
	       foreach (string s in split) 
          {
             Console.WriteLine("-{0}-", s);
  	       }
	   }
   }
}
// The example displays the following output: 
//       The delimiters are - ,.:- 
//       count =  1 .............. 
//       -one two,three:four.- 
//       count =  2 .............. 
//       -one- 
//       -two,three:four.- 
//       count =  3 .............. 
//       -one- 
//       -two- 
//       -three:four.- 
//       count =  4 .............. 
//       -one- 
//       -two- 
//       -three- 
//       -four.- 
//       count =  5 .............. 
//       -one- 
//       -two- 
//       -three- 
//       -four- 
//       --
