Convert Byte to String in VB.NET

[shadabahmad]

Hi All!

I had tried to search many forums to get this code.

Yes, just for a single line code. But when everything else failed, I decided to write my own. And it is really working good.

    Private Function Byte2Str(ByVal gByte() As Byte) As String
        Dim X As Integer
        Dim gTmp As String = ""
        For X = 0 To gByte.Length - 1
            gTmp = gTmp & Chr(gByte(X))
        Next
        Return gTmp
    End Function

Br,

this is easier:

Dim s as String = System.Text.ASCIIEncoding.ASCII.GetString(gByte)

It would work faster if you used a stringbuilder instead of string - otherwise it has to recreate the entire string with each concatenation.

Private Function Byte2Str(ByVal gByte() As Byte) As String
 
        Dim gTmp As New System.Text.StringBuilder
        For X as Int32 = 0 To (gByte.Length - 1)
            gTmp.append(Chr(gByte(X)))
        Next
        Return gTmp.ToString
 
End Function
 

But here is a way that appears to be even better from experts exchange - try this instead

   Private Function ByteArrayToString(ByVal ByteArray As Byte()) As String
        Return System.Text.Encoding.Unicode.GetString(ByteArray)
    End Function

One problem with using the system.text.encoding method is that it will assume you want the data converted to one of the encoding methods. Raw is not one of the methods available and so you can actually wind up with something you may not expect (unless you really do want ASCII, or Unicode, or UTF8).
AFAIK - if you want it raw then you need to use the looping method.
