Parity Enumeration

Specifies the parity bit for a SerialPort object.

Namespace: System.IO.Ports
Assembly: System (in system.dll)

'Declaration
Public Enumeration Parity
'Usage
Dim instance As Parity

public enum Parity
public enum Parity

 Member nameDescription
Supported by the .NET Compact FrameworkEvenSets the parity bit so that the count of bits set is an even number. 
Supported by the .NET Compact FrameworkMarkLeaves the parity bit set to 1. 
Supported by the .NET Compact FrameworkNoneNo parity check occurs. 
Supported by the .NET Compact FrameworkOddSets the parity bit so that the count of bits set is an odd number. 
Supported by the .NET Compact FrameworkSpaceLeaves the parity bit set to 0. 

Use this enumeration when setting the Parity property for a serial port connection.

Parity is an error-checking procedure in which the number of 1s must always be the same—either even or odd—for each group of bits that is transmitted without error. In modem-to-modem communications, parity is often one of the parameters that must be agreed upon by sending parties and receiving parties before transmission can take place.

The following code example displays the possible values of the Parity enumeration to the console, then prompts the user to choose one. This code example is part of a larger code example provided for the SerialPort class.

Public Shared Function SetPortParity(ByVal defaultPortParity As Parity) As Parity
    Dim newParity As String

    Console.WriteLine("Available Parity options:")
    Dim s As String
    For Each s In [Enum].GetNames(GetType(Parity))
        Console.WriteLine("   {0}", s)
    Next s

    Console.Write("Parity({0}):", defaultPortParity.ToString())
    newparity = Console.ReadLine()

    If newparity = "" Then
        newparity = defaultPortParity.ToString()
    End If

    Return CType([Enum].Parse(GetType(Parity), newParity), Parity)
End Function
