示例

以下示例使用 Settings 属性读取 appSettings 值。

// This function shows how to read the key/value
// pairs (settings collection)contained in the 
// appSettings section.
static void ReadAppSettings()
{
    try
    {

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

        // Get the appSettings section.
        System.Configuration.AppSettingsSection appSettings =
            (System.Configuration.AppSettingsSection)config.GetSection("appSettings");

        // Get the auxiliary file name.
        Console.WriteLine("Auxiliary file: {0}", config.AppSettings.File);

        // Get the settings collection (key/value pairs).
