範例

下列程式碼範例示範如何使用 Item[]。

static void GetItems()
{

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

        ConfigurationSectionCollection sections =
            config.Sections;

        ConfigurationSection section1 =
            sections["runtime"];

        ConfigurationSection section2 =
            sections[0];

        Console.WriteLine(
             "Section1: {0}", section1.SectionInformation.Name);

        Console.WriteLine(
            "Section2: {0}", section2.SectionInformation.Name);
    }
    catch (ConfigurationErrorsException err)
    {
        Console.WriteLine(err.ToString());
    }
}

Shared Sub GetItems()

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

        Dim sections _
        As ConfigurationSectionCollection = _
        config.Sections


        Dim section1 As ConfigurationSection = _
        sections.Item("runtime")

        Dim section2 As ConfigurationSection = _
        sections.Item(0)

        Console.WriteLine("Section1: {0}", _
        section1.SectionInformation.Name)

        Console.WriteLine("Section2: {0}", _
