#endregion /// /// 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) { var
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; }
Save(); } /// /// 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 /// public
void SetConnectionString(string key, string connectionString) { var
connectionSetting =
(ConnectionStringsSection)_config.GetSection("connectionStrings"); if (connectionSetting.ConnectionStrings[key]
== null) //如果不存在此节点，则添加 {
var 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; }
Save(); } /// /// 保存所作的修改 /// public
void Save() {
_config.Save();
_config = null; } }
} 使用方法： var config = new WebConfigManager();
config.SetAppSetting("StrRegex", "");读取AppSetting和ConnectionString： string fileType=ConfigurationManager.AppSettings["FileType "]; string connectionString = ConfigurationManager.ConnectionStrings["AspNetStudyConnectionString1"].ConnectionString; 该文章在 2021/5/11 18:08:52 编辑过 |
