本文实例总结了C#配置文件Section节点处理方法。分享给大家供大家参考。具体如下：

很多时候在项目开发中，我们都需要用配置文件来存储一些关于程序配置信息，这时候你可以选择INI或者app.config来存储，这里对此总结一下：

配置文件示例如下：

操作代码如下：

namespace ConsoleApplication38
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                SectionToolV2 _sectionHelper = new SectionToolV2(\"module/appSettings\");
                Console.WriteLine(_sectionHelper.GetValue(\"Googlemap\"));
                Console.WriteLine(_sectionHelper.ContainKey(\"YanZhiwei\"));
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            finally
            {
                Console.ReadLine();
            }
        }
    }
    class SectionToolV2
    {
        NameValueCollection ModulSettings = null;
        /// <summary>
        ///构造函数
        /// </summary>
        /// <param name=\"sectionName\">section名称</param>
        public SectionToolV2(string sectionName)
        {
            ModulSettings = ConfigurationManager.GetSection(sectionName) as NameValueCollection;
        }
        /// <summary>
        /// 是否包含该Section
        /// </summary>
        /// <returns></returns>
        public bool ContainSection()
        {
            return !(ModulSettings == null);
        }
        /// <summary>
        /// Section是否包含Key
        /// </summary>
        /// <param name=\"key\">键</param>
        /// <returns>值</returns>
        public bool ContainKey(string key)
        {
            if (ContainSection())
            {
                return !(ModulSettings[key] == null);
            }
            return false;
        }
        /// <summary>
        /// 根据键获取值
        /// </summary>
        /// <param name=\"Key\">键</param>
        /// <returns>当不存在键的时候，返回string.Empty</returns>
        public string GetValue(string Key)
        {
            string _value = string.Empty;
            if (ContainKey(Key))
            {
                _value = ModulSettings[Key];
            }
            return _value;
        }
    }
}
