10、配置技巧和窍门

　　在我研究和实验配置节的时候，我学到一些技巧，可是使他们更容易使用。自定义配置节的某些方面非常乏味，如所有时间一直通过调用ConfigurationManager.GetSection("someSectionName")获取SomeSectionClass。为了减轻繁琐乏味，我尝试在我的ConfigurationSection类中使用下列方式：

public class SomeConfigurationSection
{
    static SomeConfigurationSection()
    {
        // Preparation...
    }

    // Properties...

    #region GetSection Pattern
    private static SomeConfigurationSection m_section;

    /// <summary>
    /// Gets the configuration section using the default element name.
    /// </summary>
    public static SomeConfigurationSection GetSection()
    {
        return GetSection("someConfiguration");
    }

    /// <summary>
    /// Gets the configuration section using the specified element name.
    /// </summary>
    public static SomeConfigurationSection GetSection(string definedName)
    {
        if (m_section == null)
        {
            m_section = ConfigurationManager.GetSection(definedName) as
                        SomeConfigurationSection;
            if (m_section == null)
                throw new ConfigurationException("The <" + definedName +
                      "> section is not defined in your .config file!");
        }

        return m_section;
    }
    #endregion
}
