从app.config文件中检索设置的名称

Question

我需要从app.config文件中检索密钥设置的名称.

例如:

我的app.config文件:

<setting name="IGNORE_CASE" serializeAs="String">
    <value>False</value>
</setting>

我知道我可以使用以下方法检索值:

Properties.Settings.Default.IGNORE_CASE

有没有办法从我的键设置中获取字符串"IGNORE_CASE"？

此处的示例代码显示了如何遍历所有设置以读取其键和值.

摘录方便:

// Get the AppSettings section.        
// This function uses the AppSettings property
// to read the appSettings configuration 
// section.
public static void ReadAppSettings()
{
    // Get the AppSettings section.
    NameValueCollection appSettings =
       ConfigurationManager.AppSettings;

    // Get the AppSettings section elements.
    for (int i = 0; i < appSettings.Count; i++)
    {
      Console.WriteLine("#{0} Key: {1} Value: {2}",
        i, appSettings.GetKey(i), appSettings[i]);
    }
}
