C# 程序配置文件的操作（ConfigurationManager的使用）
public class ConfigureAppConfig{//静态构造,不能实例化static ConfigureAppConfig() { }/**//// <summary>/// 获取AppSettings配置节中的Key值/// </summary>/// <param name="keyName">Key's name</param>/// <returns>Key's value</returns>public static string GetAppSettingsKeyValue(string keyName){return ConfigurationManager.AppSettings.Get(keyName);}/**//// <summary>/// 获取ConnectionStrings配置节中的值/// </summary>/// <returns></returns>public static string GetConnectionStringsElementValue(){ConnectionStringSettings settings = System.Configuration.ConfigurationManager.ConnectionStrings["connectionString"];return settings.ConnectionString;}/**//// <summary>/// 保存节点中ConnectionStrings的子节点配置项的值/// </summary>/// <param name="elementValue"></param>public static void ConnectionStringsSave(string ConnectionStringsName, string elementValue){System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);config.ConnectionStrings.ConnectionStrings["connectionString"].ConnectionString = elementValue;config.Save(ConfigurationSaveMode.Modified);ConfigurationManager.RefreshSection("connectionStrings");}/**//// <summary>/// 判断appSettings中是否有此项/// </summary>private static bool AppSettingsKeyExists(string strKey, Configuration config){foreach (string str in config.AppSettings.Settings.AllKeys){if (str == strKey){return true;}}return false;}/**//// <summary>/// 保存appSettings中某key的value值/// </summary>/// <param name="strKey">key's name</param>/// <param name="newValue">value</param>public static void AppSettingsSave(string strKey, string newValue){System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);if (AppSettingsKeyExists(strKey, config)){config.AppSettings.Settings[strKey].Value = newValue;config.Save(ConfigurationSaveMode.Modified);ConfigurationManager.RefreshSection("appSettings");}}}
如果你的程序是对其它程序的配置文件进行操作,代码如下：
ExeConfigurationFileMap filemap = new ExeConfigurationFileMap();filemap.ExeConfigFilename = filePath;//配置文件路径config = ConfigurationManager.OpenMappedExeConfiguration(filemap, ConfigurationUserLevel.None);if (AppSettingsKeyExists("Refresh", config)){config.AppSettings.Settings["Refresh"].Value = M_TimeRead.ToString();}if (AppSettingsKeyExists("MachineNo", config)){config.AppSettings.Settings["MachineNo"].Value = M_MachineNo;}config.Save(ConfigurationSaveMode.Modified);ConfigurationManager.RefreshSection("appSettings");config.ConnectionStrings.ConnectionStrings["connectionString"].ConnectionString = M_ConnectionString;config.Save(ConfigurationSaveMode.Modified);ConfigurationManager.RefreshSection("connectionStrings");
数据库字符串加密
ExeConfigurationFileMap filemap = new ExeConfigurationFileMap();filemap.ExeConfigFilename = Application.ExecutablePath + ".Config"; //filePath;config = ConfigurationManager.OpenMappedExeConfiguration(filemap, ConfigurationUserLevel.None);//指定我所要的节点ConfigurationSection section = config.ConnectionStrings;if ((section.SectionInformation.IsProtected == false) && (section.ElementInformation.IsLocked == false)){//制定节点加密 section.SectionInformation.ProtectSection(protect);//即使没有修改也保存设置section.SectionInformation.ForceSave = true;//配置文件内容保存到xml config.Save(ConfigurationSaveMode.Full);}
