How to VB.NET String.Chars()

The Chars method in VB.NET's String Class is a versatile method that allows you to retrieve the character at a specified index within a string instance. By providing the desired index as an argument to the Chars method, you can obtain the character located at that position within the string.

Chars method

The Chars method returns the character as a Char data type, enabling you to perform further operations on the retrieved character as needed. This includes tasks such as comparisons, conversions, or any other operations specific to character manipulation.

System.String.Chars(ByVal index As Integer) As Char
Parameters:
  1. Integer index - The character position in the returned Character.
Returns:
  1. Char - The return Character.

For ex :

"Return test".Chars(3) return a single character 'u'

If u pass a number more than String length will return an exception

"Return test".Chars(25) will throw a System.IndexOutOfRangeException

Exceptions:
System.IndexOutOfRangeException :The index is less than zero or greater than the length of String Object.
