binary - Why does a negative SByte number have 16 bits in VB.Net? -

i asked question before comparing numbers using "and" comparing operator in if statements , have been toying around getting head wrapped around bitwise operators. have written basic code allow me see conversion of decimal number in binary format.

private sub button1_click(byval sender system.object, byval e system.eventargs) handles button1.click msgbox(converttobinary(-1)) end sub public function converttobinary(byval someinteger sbyte) string dim converted string = convert.tostring(someinteger, 2) '.padleft(8, "a"c) homecoming converted end function

notice here using sbyte paramerter - should contain 8 bits right? however, message box appears has 16 bits assigned negative numbers. positive numbers have right 8.

there no convert.tostring overload takes sbyte, sbyte beingness implicitly converted short.

vb.net binary bit signed
