Chr deals with Integers and Chars. You must convert your Integer into a Char in your VB.NET program. By using the Chr function, you can take an Integer that represents a specific character and then acquire the actual Char value.IntegerChar
Example. First, this program declares three local variables. The first variable c is assigned to the character "x". The second variable i is set to the ASCII value underlying the "x". And h shows how to convert an integer back into a character.
VB.NET program that uses Chr function 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 Output x 120 x
The letter "x". 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 Asc and Chr can be used to reverse each other's effects on a value.
Tip: 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.
And: You can use Asc and Chr in these cases to simplify your program. More information on Val and Asc is available.Val and Asc Function Examples
