下面的代码是我看完周金桥老师的ASP.NET夜话，以及上网查了一些东西后，自己写的关于对配置文件中
appSettings,connectionStrings节点的操作。关于配置文件的知识，我建议大家到周金桥老师的博客，去学习一下，我觉得他讲的
较详细些，仅仅是一个建议。如果你对我写的代码有什么想法或者疑问，请给我发邮件或加我QQ（邮件：baiyu311@yahoo.cn
QQ：602316022） 说明一下，我现在还是个学生，有些技术上的问题未必会懂，但我坚信通过我们的努力是可以客服它的。还有我最近在学习Linux，很想做一个Linux人，开源嘛，如果你有兴趣也可以联系我。期待每位上进的朋友，嘿嘿。。。。下面是我的代码： using System; using System.Configuration; using System.Web; using System.Web.Configuration; namespace myConfiguration { #region 配置信息的操作类 /// <summary> /// 配置信息的操作 /// </summary> public class ConfigurationOperator:IDisposable { #region 变量的声明 /// <summary> /// Configuration Object /// </summary> private Configuration config; #endregion #region 构造函数，有参数(当前应用程序的虚拟路径) /// <summary> /// 构造函数，有参数(当前应用程序的虚拟路径) /// </summary> public ConfigurationOperator() : this(HttpContext.Current.Request.ApplicationPath) { } #endregion #region 构造函数，有参数(其他应用程序的虚拟路径) /// <summary> /// 构造函数，有参数(其他应用程序的虚拟路径) /// </summary> /// <param name="path">其他应用程序的虚拟路径</param> public ConfigurationOperator(string path) { config = WebConfigurationManager.OpenWebConfiguration(path); } #endregion #region 获取当前或其他应用程序配置文件中appSettings的所有keyName方法 /// <summary> /// 定义获取当前或其他应用程序appSettings的所有keyName方法 /// </summary> /// <returns>返回appSettings的所有keyName</returns> public string[] ActiveALLAppSettingsSection() { AppSettingsSection appSettings = (AppSettingsSection)config.GetSection("appSettings"); string[] appKeys = appSettings.Settings.AllKeys; return appKeys; } #endregion #region 设置当前或者其他应用程序配置文件中的appSettings节点 /// <summary> /// 定义设置当前或者其他应用程序配置文件中的appSettings节点 /// </summary> /// <param name="key">keyName</param> /// <param name="value">keyValue</param> public void SetAppSettingsSection(string key,string value) { AppSettingsSection appSettings = (AppSettingsSection)config.GetSection("appSettings"); if (appSettings.Settings[key]!=null) { appSettings.Settings[key].Value = value; this.Save(); } else { appSettings.Settings.Add(key, value); this.Save(); } } #endregion #region 删除当前或者其他应用程序配置文件中的appSettings节点 /// <summary> /// 定义删除当前或者其他应用程序配置文件中的appSettings节点 /// </summary> /// <param name="key">keyName</param> /// <returns>删除成功返回true，删除失败返回false</returns> public bool RemoveAppSettingsSection(string key) { AppSettingsSection appSettings = (AppSettingsSection)config.GetSection("appSettings"); if (appSettings.Settings[key] != null) { appSettings.Settings.Remove(key); this.Save(); return true; } else { return false; } } #endregion #region 获取当前或其他应用程序配置文件中connectionStrings节点的所有ConnectionString /// <summary> /// 定义获取当前或其他应用程序配置文件中connectionStrings节点的所有ConnectionString /// </summary> /// <returns>返回connectionStrings节点的所有ConnectionString</returns> public string[] ALLConnectionStrings() { ConnectionStringsSection conSection = (ConnectionStringsSection)config.GetSection("connectionStrings"); ConnectionStringSettingsCollection conCollection = conSection.ConnectionStrings; string[] conStrings = new string[conSection.ConnectionStrings.Count]; int i = 0; foreach (ConnectionStringSettings conSetting in conCollection) { conStrings[i++] = conSetting.ConnectionString; } return conStrings; } #endregion #region 设置当前或其他应用程序配置文件中ConnectionString节点 /// <summary> /// 定义设置当前或其他应用程序配置文件中ConnectionString节点 /// </summary> /// <param name="name">connectionStrings Name</param> /// <param name="ConnectionString">connectionStrings ConnectionString</param> /// <param name="providerName">connectionStrings ProviderName</param> public void SetConnectionStringsSection(string name, string ConnectionString, string providerName) { ConnectionStringsSection conSection=(ConnectionStringsSection)config.GetSection("connectionStrings"); if (conSection.ConnectionStrings[name] != null) { conSection.ConnectionStrings[name].ConnectionString = ConnectionString; conSection.ConnectionStrings[name].ProviderName = providerName; this.Save(); } else { ConnectionStringSettings conSettings = new ConnectionStringSettings(name, ConnectionString, providerName); conSection.ConnectionStrings.Add(conSettings); this.Save(); } } #endregion #region 删除当前或其他应用程序配置文件中ConnectionString节点 /// <summary> /// 定义删除当前或其他应用程序配置文件中ConnectionString节点 /// </summary> /// <param name="name">ConnectionStrings Name</param> /// <returns>删除成功返回true，删除失败返回false</returns> public bool RemoveConnectionStringsSection(string name) { ConnectionStringsSection conSection = (ConnectionStringsSection)config.GetSection("connectionStrings"); if (conSection.ConnectionStrings[name] != null) { conSection.ConnectionStrings.Remove(name); this.Save(); return true; } else { return false; } } #endregion #region 保存配置文件，并重新赋值config为null /// <summary> /// 定义保存配置文件的方法 /// </summary> public void Save() { config.Save(); config = null; } #endregion #region 释放配置文件对象 /// <summary> /// 释放配置文件对象 /// </summary> public void Dispose() { if (config != null) { config.Save(); } } #endregion } #endregion } |
