Convert Byte to String in VB.NET

1 New Member
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.

Expand|Select|Wrap|Line Numbers
  1.     Private Function Byte2Str(ByVal gByte() As Byte) As String
  2.         Dim X As Integer
  3.         Dim gTmp As String = ""
  4.         For X = 0 To gByte.Length - 1
  5.             gTmp = gTmp & Chr(gByte(X))
  6.         Next
  7.         Return gTmp
  8.     End Function

this is easier:
Expand|Select|Wrap|Line Numbers
  1. 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.

Expand|Select|Wrap|Line Numbers
  1. Private Function Byte2Str(ByVal gByte() As Byte) As String
  3.         Dim gTmp As New System.Text.StringBuilder
  4.         For X as Int32 = 0 To (gByte.Length - 1)
  5.             gTmp.append(Chr(gByte(X)))
  6.         Next
  7.         Return gTmp.ToString
  9. End Function
But here is a way that appears to be even better from experts exchange - try this instead

Expand|Select|Wrap|Line Numbers
  1.    Private Function ByteArrayToString(ByVal ByteArray As Byte()) As String
  2.         Return System.Text.Encoding.Unicode.GetString(ByteArray)
  3.     End Function

One problem with using the system.text.enc oding 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.

I have a string that I received from a web service call and I want to write it to a Stream. I cannot figure out how to access the string as a byte array and write it to the Stream. Any thoughts. I looked at Byte.Parse() but it will only convert a string represntation of a number and convert it to a byte. Thanks, Brian

Hi all, I'm looking for the fastest way to convert an array of bytes to String. I also need to convert a String back to its original Byte() representation. Convert.ToBase64String and Convert.FromBase64String seem like the closest thing I can find to what I'm looking for baked into the base class library. Can anyone suggest a better way to do this? TIA - Bob

How do I test a byte string in Python? I want to manually convert (no libraries or functions) a UTF-8 string into UTF-16. My basic solution is to read from the stream some number of UTF-8 bytes, convert them into codepoints, then convert those codepoints into UTF-16 bytes. I want to code this myself, but I don't understand how to test the actual byte sequence. Let's say I use the following code to ensure I have a UTF-8 encoding (from Evan...
