Writing to app.config

[zdavis]

Hi Everyone,

I realize that writing to the app.config file may not be best practices. However, how do you write to a user defined sectionGroup in the app.config file. I can't figure it out thanks.

I sometimes updtae a App.config file by writing over the entire file since it's xml. I never got any problems with this so i continue to overwrite the app.config if there is any need for configuration changes to a program.

This user defined group you asked about, you want to give an example of such a group with xml?

I guess technically it is considered a sectionGroup.


In this part of my app.config I declare my sectionGroup

<configSections>
    <sectionGroup name="SerialPort">
      <section name="SerialPortInformation" type="Scale_Simulator.SerialPortConfigHandler,Scale Simulator"/>
    </sectionGroup>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
      <section name="Scale_Simulator.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup>
  </configSections>

Here is where I set the values

<SerialPort>
    <SerialPortInformation>
      <port></port>
      <baudrate></baudrate>
      <databits></databits>
      <parity></parity>
      <stopbits></stopbits>
      <flow></flow>
    </SerialPortInformation>
  </SerialPort>

When you first start the program a serial port won't be setup that is why they are empty.

What I have so far for saving is this

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
                               
       
config.GetSection("SerialPort/SerialPortInformation").SectionInformation.SetRawXml("<SerialPortInformation>" + "\r\n" + "<port>" + cboPort.Text + "</port>" + "\r\n" + "<baudrate>" + cbobaudRate.Text + "</baudrate>" + "\r\n" + "<databits>" + cboDataBits.Text + "</databits>" + "\r\n" + "<parity>" + cboParity.Text + "</parity>" + "\r\n" + "<stopbits>" + cboStopBits.Text + "</stopbits>" + "\r\n" + "<flow>" + cboHandShake.Text + "</flow>" + "\r\n" + "</SerialPortInformation>");
config.Save(ConfigurationSaveMode.Full, true);
ConfigurationSection mysection = config.GetSection("SerialPort/SerialPortInformation");

The information is not saving to the file.

Is there a better way to do this????

thanks,
