vb.net - New Random in a For-Next-Statement Repeats the Same Value -


i creating 3 random bytes in for-next-statement.

however, same each for-next, example "333", or "777".

i wonder why , doing wrong.

private sub button1_click(sender object, e eventargs) handles button1.click      dim s string = string.empty      integer = 0 2         s += getrandombyte().tostring     next      me.textbox1.text = s  end sub  public function getrandombyte(optional byval ulow byte = 1, optional byval uhigh byte = 9) byte      dim r new random     dim b integer = r.next(cint(ulow), cint(uhigh + 1))      return b  end function

in constructor new random, give new seed each time. use current timestamp's hashcode value

new random(now.gethashcode)
