Net操作配置文件(Web.config|App.config)通用类
一、Net操作web.config通用类(代码如下):
using System; using System.Configuration; using System.Web; using System.Web.Configuration; /// ConfigurationOperator 的摘要说明 public class ConfigurationOperator : IDisposable { private Configuration config; public ConfigurationOperator() : this(HttpContext.Current.Request.ApplicationPath) { } public ConfigurationOperator(string path) { config = WebConfigurationManager.OpenWebConfiguration(path); } /// 设置应用程序配置节点,如果已经存在此节点,则会修改该节点的值,否则添加此节点 /// /// 节点名称 /// 节点值 public void SetAppSetting(string key, string value) { AppSettingsSection appSetting = (AppSettingsSection)config.GetSection("appSettings"); if (appSetting.Settings[key] == null)//如果不存在此节点,则添加 { appSetting.Settings.Add(key, value); } else//如果存在此节点,则修改 { appSetting.Settings[key].Value = value; } } /// /// 设置数据库连接字符串节点,如果不存在此节点,则会添加此节点及对应的值,存在则修改 /// /// 节点名称 /// 节点值 public void SetConnectionString(string key, string connectionString) { ConnectionStringsSection connectionSetting = (ConnectionStringsSection)config.GetSection("connectionStrings"); if (connectionSetting.ConnectionStrings[key] == null)//如果不存在此节点,则添加 { ConnectionStringSettings connectionStringSettings = new ConnectionStringSettings(key, connectionString); connectionSetting.ConnectionStrings.Add(connectionStringSettings); } else//如果存在此节点,则修改 { connectionSetting.ConnectionStrings[key].ConnectionString = connectionString; } } /// /// 保存所作的修改 public void Save() { config.Save(); config = null; } public void Dispose() { if (config != null) { config.Save(); } } }
二、调用方法:
// 连接字符串 string connectionString = string.Format("Data Source={0};Initial Catalog={1};User ID={2};Password={3}; max pool size=150", tbx_ip.Text.Trim(), tbx_dbname.Text.Trim(), tbx_username.Text.Trim(), tbx_pwd.Text.Trim()); ConfigurationOperator config = new ConfigurationOperator(); config.SetConnectionString("defaultConnection", connectionString); config.Save();
