Examples

The following example shows how to use the GetSection method to access a custom section. For the complete example code that defines a class that stores information for the CustomSection section, see the Configuration class overview.

// Show how to use the GetSection(string) method.
static void GetCustomSection()
{
    try
    {

        CustomSection customSection;

        // Get the current configuration file.
        System.Configuration.Configuration config =
                ConfigurationManager.OpenExeConfiguration(
                ConfigurationUserLevel.None) as Configuration;

        customSection =
            config.GetSection("CustomSection") as CustomSection;

        Console.WriteLine("Section name: {0}", customSection.Name);
        Console.WriteLine("Url: {0}", customSection.Url);
        Console.WriteLine("Port: {0}", customSection.Port);
    }
    catch (ConfigurationErrorsException err)
    {
        Console.WriteLine("Using GetSection(string): {0}", err.ToString());
    }
}

' Show how to use the GetSection(string) method.
Public Shared Sub GetCustomSection()
    Try

        Dim customSection As CustomSection

        ' Get the current configuration file.
        Dim config As System.Configuration.Configuration = TryCast(ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None), Configuration)

        customSection = TryCast(config.GetSection("CustomSection"), CustomSection)

        Console.WriteLine("Section name: {0}", customSection.Name)
        Console.WriteLine("Url: {0}", customSection.Url)
        Console.WriteLine("Port: {0}", customSection.Port)

    Catch err As ConfigurationErrorsException
        Console.WriteLine("Using GetSection(string): {0}", err.ToString())
    End Try

End Sub

Remarks

Configuration settings are contained within sections that group similar settings together for convenience. The GetSection method retrieves a configuration section by its name.
