Voorbeelden

In het volgende voorbeeld ziet u hoe u de Keys eigenschap gebruikt.

static void GetKeys()
{

    try
    {
        System.Configuration.Configuration config =
        ConfigurationManager.OpenExeConfiguration(
        ConfigurationUserLevel.None);

        ConfigurationSectionCollection sections =
            config.Sections;

        foreach (string key in sections.Keys)
        {

            Console.WriteLine(
             "Key value: {0}", key);
        }
    }
    catch (ConfigurationErrorsException err)
    {
        Console.WriteLine(err.ToString());
    }
}

Shared Sub GetKeys()

    Try
        Dim config _
        As System.Configuration.Configuration = _
        ConfigurationManager.OpenExeConfiguration( _
        ConfigurationUserLevel.None)

        Dim sections _
        As ConfigurationSectionCollection = _
        config.Sections


        Dim key As String
        For Each key In sections.Keys


            Console.WriteLine("Key value: {0}", key)
        Next key


    Catch err As ConfigurationErrorsException
        Console.WriteLine(err.ToString())
    End Try
