配置文件内容如下：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="mySection" type="System.Configuration.NameValueSectionHandler"/>
<section name="mySingleTagSection" type="System.Configuration.SingleTagSectionHandler"/>

<sectionGroup name="mySections">

</sectionGroup>
</configSections>
<mySection>

</configuration>
代码片断如下：
private static void TestAppSettings()
{
Console.WriteLine("TestAppSettings ...");
NameValueCollection config = ConfigurationSettings.AppSettings;
Console.WriteLine("value1:" + config["key1"]);
Console.WriteLine("value2:" + config["key2"]);
Console.WriteLine();
}
private static void TestSection()
{

Console.WriteLine();
}
private static void TestSingleTagSection()
