The problem is not fully defined. The bytes can represent text, this is one possible option, and other option would be showing the bytes as separate decimal of hexadecimal strings. Or something else.
First options is shown in Solution 1, which also covers ASCII, but the encoding can be different, depending on some requirements.

The second option may require something like;

C#

byte[] example = new byte { 1, 2, 3, };
System.StringBuilder stringBuilder = new System.StringBuilder();
foreach(byte in example)
    stringBuilder.Append(byte.ToString() + ", "); // a format parameter can be added
yourTextBox = stringBuilder.ToString.Trim(); // not the most efficient, just for simplicity

Solution 1

You could do this:

byte[] example = new byte { 0x01, 0x02, 0x03 };
YourTextBox.Text = System.Text.Encoding.UTF8.GetString(example)

I voted 4. You could have mentioned that this is not the only possible interpretation of the vague OP's request.
Besides, 1, 2 and 3 don't give any readable text. Could be, say, 65, 66, 67 ("ABC").
Please see my answer, where I credit yours.
