Chr

In VB.NET programs Chr() deals with Integers and Chars. Often we must convert Integers into Chars. And with Chr() we can perform this conversion easily.

By using the Chr function, you can take an Integer that represents a specific character and then acquire the actual Char value. An understanding of ASCII codes is helpful in learning about Chr.

Example

Here the first variable "c" is assigned to the character "x". The second variable "i" is set to the ASCII value underlying the "x".

Module Module1
    Sub Main()
        Dim c As Char = "x"c ' Input character.
        Dim i As Integer = Asc(c) ' Convert to ascii integer.
        Dim h As Char = Chr(i) ' Convert ascii integer to char.

        Console.WriteLine(c)
        Console.WriteLine(i)
        Console.WriteLine(h)
    End Sub
End Module
x
120
x

Program details

You can see that the ASCII representation for "x" is equal to 120. Then, the character representation (Chr) of 120 is equal to "x".

Here, we showed how you can use Asc and Chr to manipulate ASCII integers for characters in the VB.NET language. In some algorithms, the Integer representation of a Char is more useful.
