May 11, 2014

Gets the character at a specified character position in the current string.

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

'Declaration
Public ReadOnly Property Chars ( _
	index As Integer _
) As Char

Parameters

index
Type: System.Int32
A character position in the current string.

Property Value

Type: System.Char
The Unicode character at position index.

ExceptionCondition
IndexOutOfRangeException

index is greater than or equal to the length of this object or less than zero.

The index parameter is zero-based.

This property returns the Char object at the position specified by the index parameter. However, a Unicode character might be represented by more than one Char object. Use the System.Globalization.StringInfo class to work with Unicode characters instead of Char objects.

In C#, the Chars property is an indexer. In Visual Basic, it is the default property of the String class. Each Char object in the string can be accessed by using code such as the following.


Dim str1 As String = "Test"
For ctr As Integer = 0 To str1.Length - 1
   outputBlock.Text += String.Format("{0} ", str1(ctr))
Next
' The example displays the following output:
'      T e s t         


The following code example demonstrates how you can use the Chars property in a routine to validate a string.


outputBlock.Text += "Type a string : "
Dim myString As String = Console.ReadLine()
Dim i As Integer
For i = 0 To myString.Length - 1
   If Uri.IsHexDigit(myString.Chars(i)) Then
      outputBlock.Text += String.Format("{0} is a hexadecimal digit.", myString.Chars(i)) + vbCrLf
   Else
      outputBlock.Text += String.Format("{0} is not a hexadecimal digit.", myString.Chars(i)) + vbCrLf
   End If
