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:
 
 代码如下:
<configuration>
<configSections>
<sectionGroup name=”module”>
<section name=”appSettings” type=”System.Configuration.NameValueFileSectionHandler”/>
</sectionGroup>
</configSections>
<module>
<appSettings>
<!–谷歌地图–>
<add key=”Googlemap” value=”1″/>
<!–箱实时状态信息汇总–>
<add key=”Cab_rt” value=”1″/>
</appSettings>
</module>
</configuration>
操作代码如下:
 
 代码如下:
using System.Collections.Specialized;
using System.Configuration;
 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;
 
 }
 
 }
 
 }
