Can I Convert A Byte() to a string?

Question

I need a solution to my current code, I am trying to save text to a file from a Text Box, and add a string to it. My following code is:

 Dim fs As FileStream = File.Create(fileName.Text)

    ' Add text to the file. 

    Dim info As Byte() = New UTF8Encoding(True).GetBytes(CodeBox.Text)

    Dim Code = "-- Made with LUA Creator by Sam v1.9
    " + info
    fs.Write(Code, 0, Code.Length)
    fs.Close()

    MsgBox("File saved as " + fileName.Text)

But Visual Studio says that I cannot use "+" operator with strings & bytes:

Error BC30452 Operator '+' is not defined for types 'String' and 'Byte()'.

Anyone have a solution? Sorry if this is a duplicate, I couldn't find it anywhere here so I just asked myself. Thanks.

& is for string concatenation; + is for addition. Try concatenating your string with the TextBox, before usingGetBytes: "-- Made with..." & CodeBox.Text) — Justin Ryan

"Can I Convert A Byte() to a string?" Short answer is yes, but that doesn't look like what you're really wanting to do.

You're trying to concatenate a String with a Byte array, which Dim Code has no idea what the end result is supposed to be.

FileStream.Write() requires a Byte array so you can try a couple of things

Concatenate the string from the TextBox with your "header" information then turn it into a Byte array.

Dim fs As FileStream = File.Create(fileName.Text)

' Add text to the file. 
Dim Code As Byte() = New UTF8Encoding(true).GetBytes("-- Made with LUA Creator by Sam v1.9 " & CodeBox.Text)
fs.Write(Code, 0, Code.Length)
fs.Close()

Write your "header" information, then write the Textbox information

Dim fs As FileStream = File.Create(fileName.Text)

' Add text to the file. 
Dim header As Byte() = New UTF8Encoding(true).GetBytes("-- Made with LUA Creator by Sam v1.9 ")
Dim info As Byte() = New UTF8Encoding(True).GetBytes(CodeBox.Text)
fs.Write(header, 0, header.Length)
fs.Write(info, 0, info.Length)
fs.Close()
