Hi,

Can I please have a very small code snippet to convert byte[] to string and
back using Base64? Advance thanks.

Hello Samba,

string b = Convert.ToBase64String(bytes);
byte[] bytesagain = Convert.FromBase64String(b);

I'm using this functionality to try to load an image that's returned to me
in an XML file. The converstion to the byte array works fine.

Than I move the byte array into a memory Stream using ...

Dim stmBLOBData As New MemoryStream(binaryData)

which also seems to work fine, but the following line which should actually
create the image failes with a "Invalid Parameter used".

img = Image.FromStream(stmBLOBData)

Is this really a problem with my conversion? Any ideas how to debug?

Hello Steve,

From/To base64 conversion is lossless...

not sure what your problem is.

arrImg...is your bytearray ;-)

Dim _stream As New MemoryStream(_arrImg, True)
stream.Write(_arrImg, 0, _arrImg.Length)
PictureBox1.Image = New Bitmap(New Bitmap(_stream))
_stream.Close()
