.NET Framework Class Library

String..::.ToCharArray Method

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

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

Syntax

Visual Basic (Declaration)

Public Function ToCharArray As Char()

Visual Basic (Usage)

Dim instance As String
Dim returnValue As Char()

returnValue = instance.ToCharArray()

public char[] ToCharArray()

Visual C++

public:
array<wchar_t>^ ToCharArray()

JScript

public function ToCharArray() : char[]

Return Value

Type: array<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.

Examples

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

Visual Basic

Public Class StringSplit2
   Public Shared Sub Main()

      Dim delimStr As String = " ,.:"
      Dim delimiter As Char() = delimStr.ToCharArray()
      Dim words As String = "one two,three:four."
      Dim split As String() = Nothing

      Console.WriteLine("The delimiters are -{0}-", delimStr)
      Dim x As Integer
      For x = 1 To 5
         split = words.Split(delimiter, x)
         Console.WriteLine(ControlChars.Cr + "count = {0,2} ..............", x)
         Dim s As String
         For Each s In  split
            Console.WriteLine("-{0}-", s)
         Next s
      Next x
   End Sub 
End Class

'       The delimiters are - ,.:-
