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".
And The "h" variable (the third one) shows how to convert an integer back into a character.
Important The program gets a Char from an Integer. This is useful for calling methods that require Char.
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 Modulex
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".
So The Asc and Chr functions can be used to reverse each other's effects on a value.
Warning The Asc and Chr functions are not available in the C# language. They are only useful in VB.NET programs.
Summary. 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.
