Convert String to Char () array in vb.net

In this articles I am going to convert String to Char () array. You can use overloaded ToCharArray method of string object. You can easily buffer character array from a string and its return a new Char () array. I have used different methods and different way to use in below code.



First method is simple to convert string to char array use ToCharArray method of string, ToCharArray method receive a character  array from the contents of a string and second I used string reader class that to reads from the specified string.

Code:

Imports System.IO
Module Module1
    Sub Main()
        Dim str As [String] = "hello friends"
        'String to char array
        Dim chArray As Char() = str.ToCharArray()
        Console.Write(chArray(0))
        Console.Write(chArray(1))
        Console.Write(chArray(2))
        Console.Write(chArray(3))
        Console.Write(chArray(4))
        Console.Write(chArray(5))
        Console.Write(chArray(6))
        Console.Write(chArray(7))
        Console.Write(chArray(8))
        Console.Write(chArray(9))
        Console.Write(chArray(10))
        Console.Write(chArray(11))
        Console.Write(chArray(12))
        Console.WriteLine()
        Console.WriteLine()

        Dim str1 As New [String](chArray)
        Console.Write(str1)
        Console.WriteLine()
        Console.WriteLine()

        Dim str2 As String = "Hello World"
        Console.Write(str2(0))
        Console.WriteLine()
        Console.WriteLine()

        Dim sr As New StringReader(str)
        sr.Read(chArray, 0, 11)
        Console.WriteLine(chArray)
        sr.Close()
        Console.WriteLine()
        Console.WriteLine()

       ' use for loop
        For i As Integer = 0 To str.Length - 1
            ' Get character from array.
            Dim length As Char = str(i)
            Console.Write(length)
        Next
        Console.WriteLine()
        Console.WriteLine()

        'using foreach
        For Each c As Char In str
            Console.Write(c)
        Next
        Console.ReadLine()
    End Sub
End Module

Output:
