Get character from BYTE value

[Alain Dekker]

Simple question this:

If I receive a list of byte values, eg. [104][101][108][108][111], this
would be "hello" as a string. Is there a simple command (part of the .NET
library) to convert from [104] into "h"? Using VB.NET 2003.

Thanks,
Alain

The CHR() function will do the conversion from a numeric value into a
character, but you need to remove the [] before trying to convert the string
to a numeric. Look at the Trim function for how to remove multiple
characters from a string

I think this is what you want:

Dim values() As Byte = {104, 101, 108, 108, 111}
Dim s As String = UTF8Encoding.ASCII.GetString(values)
Console.WriteLine(s)

Dim s As String = UTF8Encoding.ASCII.GetString(values)

I'd write 'Encoding.ASCII' instead of 'UTF8Encoding.ASCII', which will
work too but which semantically doesn't make much sense.

Thanks, yes the System.Encoding.ASCII method turned out to be the one I
wanted. UNICODE takes some getting used to! Its all good stuff, but when
you're writing applications that never need the UNICODE, its a complication
that sometimes I wish could be "switched off".

Thanks again,
Alain
