Question

C# ToBase64String XML

Markus Freitag 3,791

Hello,

to get converted code readable.

// XML
 isActive="true" written="QjQ0QTA0OTQ3Mg==" read="QjQ0QTA0OTQ3Mg=="

// Code C# Convert
 codeWritten = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(codeWritten));

Is there a tool a way to get this string readable?
Notepad++ ?

So that I can save control characters as XML I have to convert them.

Or I would have to write my own tool.
Or about a browser that recognizes that?

Thanks for tips and hints in advance.

there is no native xml support for base64 strings.

you can use notepad++ to decode (select and decode) and there are websites that you can paste a base64 string and decode.

but why are you using base64 instead of xml encoding of control characters?

Hello @Bruce (SqlWork.com) ,

but why are you using base64 instead of xml encoding of control characters?

Can you please create an example of how you would do it? I did it this way because I don't know any other solution.

What would be better?

Thanks in advance.

If you are using .NET, consider Convert.ToHexString and Convert.FromHexString. You will have strings like “27 F0 1B…”, which reflect your bytes and are easier to read. (In case of .NET Framework, use BitConverter.ToString and other equivalents).

Xml uses the Unicode escape syntax

Hello,

I think your suggestion is good.
But how to apply it correctly?

Convert.ToHexString and Convert.FromHexString

Can you make an example? At moment i can't see ToHexString. Need I a special assembly?
I would like to have the string in the XML more readable if that is possible.

I get this string from a hand scanner and need to save the content as XML.

iso-iec-15434

byte[] bytes = Encoding.UTF8.GetBytes(message); string help = BitConverter.ToString(bytes); // Merge all bytes into a string of bytes StringBuilder builder = new StringBuilder(); for (int i = 0; i < bytes.Length; i++) { builder.Append(bytes[i].ToString("X2")); } Log.Info(builder.ToString()); 29 0x1D ^] GS IS Group Separator

Convert.ToHexString and Convert.FromHexString.

in .NET 5.0 and later you can use the Convert.ToHexString() method.

I have .NET 4.7 framework
