How to get the charater at a specific position of a string in Visual Basic?

Question

I want to get a character available at specific position in Visual Basic for example the string is "APPLE".

I want to get the 3rd character in the string which is "P".

Solution

You can look at a string as an array of Chars. The characters are indexed from 0 to the number of characters minus 1.

' For the 3rd character (the second P):

Dim s As String = "APPLE"
Dim ch As Char =  s(2) ' = 'P',  where s(0) is "A"

Or

Dim ch2 As Char = s.Chars(2) 'According to @schlebe's comment

Or

Dim substr As String = s.Substring(2, 1) 's.Substring(0, 1) is "A"

Or

Dim substr As String = Mid(s, 3, 1) 'Mid(s, 1, 1) is "A" (this is a relict from VB6)

Note: Use the first variant if you want to return a Char. The two others return a String of length 1. The common .NET way available in all the languages is to use the method Substring, where as the function Mid is VB specific and was introduced in order to facilitate the transition from VB6 to VB.NET.

You can also add Dim ch As Char = s.Chars(3) '
