配置文件：与应用程序一起打包，是对应用程序的配置，方便管理。
一、基本操作，读写appSettings：
/// <summary>
/// 添加appsettings,如果appKey不存在则添加，存在则更新
/// </summary>
/// <param name="appKey"></param>
/// <param name="appValue"></param>
public static void AddConfig(string appKey, string appValue)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
if (ConfigurationManager.AppSettings[appKey] == null)
config.AppSettings.Settings.Add(appKey, appValue);
else
config.AppSettings.Settings[appKey].Value = appValue;
config.Save();
ConfigurationManager.RefreshSection("appSettings");
}
/// <summary>
/// 更新指定appKey的appsettings
/// </summary>
/// <param name="appKey"></param>
/// <param name="appValue"></param>
public static void UpdateConfig(string appKey, string appValue)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings[appKey].Value = appValue;
config.Save(); //ConfigurationSaveMode.Full
ConfigurationManager.RefreshSection("appSettings"); //刷新命名节，在下次检索它时将从磁盘重新读取它。记住应用程序要刷新节点
}
/// <summary>
/// 读取指定appKey的appsettings
/// </summary>
/// <param name="appKey"></param>
/// <returns></returns>
public static string ReadConfig(string appKey)
{
string read = ConfigurationManager.AppSettings[appKey];
return read;
}
/// <summary>
/// 删除指定appKey的appsettings
/// </summary>
/// <param name="appKey"></param>
public static void DeleteConfig(string appKey)
{
Configuration config=ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
if (ConfigurationManager.AppSettings[appKey] != null)
{
config.AppSettings.Settings.Remove(appKey);
config.Save();
ConfigurationManager.RefreshSection("appSettings");
}
}二、自定义操作
1、新建section类
class ConfigSectionData : ConfigurationSection
{
[ConfigurationProperty("key")]
public string Key
{
get { return (string)this["key"]; }
set { this["key"] = value; }
}
[ConfigurationProperty("vaule")]
public string Value
{
get { return (string)this["vaule"]; }
set { this["vaule"] = value; }
}
}2、编写调用函数
/// <summary>
/// 读配置节点组value
/// </summary>
/// <param name="name"></param>
/// <returns></returns>
public static string ReadConfigGropValue(string sectionGroup, string name)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
if (config.GetSectionGroup(sectionGroup)!=null)
{
if (config.SectionGroups[sectionGroup].Sections[name] != null)
{
ConfigSectionData ReadGroupValue = config.SectionGroups[sectionGroup].Sections[name] as ConfigSectionData;
return ReadGroupValue.Value;
}
}
return null;
}
/// <summary>
/// 根据index读配置节点组value
/// </summary>
/// <param name="name"></param>
/// <returns></returns>
public static string ReadConfigGropValue(string sectionGroup, int index)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
if (config.GetSectionGroup(sectionGroup) != null)
{
ConfigSectionData ReadGroupValue = config.SectionGroups[sectionGroup].Sections[index] as ConfigSectionData;
return ReadGroupValue.Value;
}
return null;
}

}
}
return null;
}
