Hello,
how can I put two byte in one String , and I want that this one byte be
behind second?


Like this : Dim b1,b2 As Byte ("b1=2D") ("b2=52")
Dim s As String = b1&b2 ("2D52")

Did this code put first byte behaind second in "str" (string)?

Are you looking for

Dim s As String = b1.ToString("X2") & b2.ToString("X2")

Yes,
but I have one more question. Can I put second byte in different time in
string? Because, I have situation like this, I read two byte from serial
port, with distance, and because I nead put first byte diferend on second in
string.

What is "X" in Yours code? What this mean?

Thank you !

Hi Bojan,

You can assemble the string any way you want. The X2 means output as 2-digit hexadecimal value.

Sure, just use the & operator to append the new string.

Dim s As String = b1.ToString("X2")
....
s = s & b2.ToString("X2")

If you actually have many more bytes, you should consider using the
System.Text.StringBuilder class instead.

It means that the number should be formatted with upper-case
hexadecimal digits. See
