How to save byte[] in c# application settings

Question

I am trying to save a byte array (byte[]) in c# application settings that is returned by Object List View.

Can anyone give me a solution on how to save byte array in c# application settings? or some trick on how to convert byte[] to something like a string then store, then retrieve and again convert it to byte array and give it back to object list view.

Answer 1

One of the most common ways to make a string from an array of bytes is encoding them in Base-64:

string encoded = System.Convert.ToBase64String(toEncodeAsBytes);

Use

byte[] bytes = System.Convert.FromBase64String(encoded);

to get your bytes back.

The canonical way to do this is to convert the byte[] to a string via base64 and the other way round.

Answer 3

By Different way you can convert Byte array to string and string to byte array. Like this :

1)

string asciiString = ASCIIEncoding.ASCII.GetString(byteArray);

byte[] byte = ASCIIEncoding.ASCII.GetBytes(asciiString);

2)

string base64String = System.Convert.ToBase64String(byteArray);

byte[] byte = System.Convert.FromBase64String(base64String);

3)

string utf8String = System.Text.Encoding.UTF8.GetString(byteArray);

byte[] byte = System.Text.Encoding.UTF8.GetBytes(utf8String);

you can also use System.Text.Encoding.BigEndianUnicode, System.Text.Encoding.Unicode, and System.Text.Encoding.UTF32 for converting Byte Array to string and string to Byte Array.

Hope, It should help you.
