The call to Encoding.ASCII.GetBytes returns a byte array. You can't just convert the whole object to a string, or you get the class type (System.byte[] in this case).

Instead, call ToString on each item (byte) in the collection:

textBox1.Text =
    string.Join(",", Encoding.ASCII.GetBytes("hello").Select(b => b.ToString()));

Output:

"104,101,108,108,111"

Or if you don't want a delimiter:

textBox1.Text = new string(
    Encoding.ASCII.GetBytes("hello").SelectMany(b => b.ToString()).ToArray());

Output:

"104101108108111"
