Answer 1

Hi,

I you want to convert an array of bytes to string, you may use:

            byte[] bytes = { 1,2,3,4 };

            string StringByte= BitConverter.ToString(bytes);

Grammar is important.  I think what you mean is

how i can display [bytes that i got by converting a string] in a visual studio C# textbox?

I'm not sure what you mean by "bytes that I got by converting a string".  But I'll assume you mean an array of bytes.

First of all, to set the text of a textbox you would use:

textBox1.Text = "Hello";

To convert a byte array to a string of hex digits you might use something like this:

byte[] myBytes = new byte[] { 72, 101, 108, 108, 111 };
textBox1.Text = string.Join( " ", myBytes.Select( x => x.ToString( "X2" ) ) );

This results in "48 65 6C 6C 6F"

Or if you want to recover the string from an array of bytes you can use:

textBox1.Text = Encoding.UTF8.GetString( myBytes );

...or whatever encoding you are using.

Not sure which of these (if any) you are actually after.
