读写ASP.NET web.config

如果你需要读写ASP.NET web.config. 请参考System.Web.Configuration.

在具体写代码以前，请先引用 System.Data, System.Collection,System.Web.Configuration,System.ComponetModule.

写入：

        Configuration chapter = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
        if (chapter != null)
        {

            AppSettingsSection cfgHandler = chapter.GetSection("appSettings") as AppSettingsSection;
            ConfigHander handler = new ConfigHander();
            handler.FirstName = "Gary";
            handler.LastName = "Yang";
            handler.SectionInformation.ForceSave = true;
            cfgHandler.Settings.Add("Gary", "GaryYang");
            chapter.Save();
        }

 如果你想以对象的形式添加到web.config中，你需要实现相对的类:

 这其实是因为.Net Framework提供了IConfigurationSectionHandler接口.

public class ConfigHander : ConfigurationSection
{
    [ConfigurationProperty("LastName", IsRequired = false, DefaultValue = "NotGiven")]
    public string LastName
    {
        get {
            return (string)base["LastName"];
        }
        set
        {
            base["LastName"] = value;
        }
    }
    [ConfigurationProperty("FirstName", IsRequired = false, DefaultValue = "NotGiven")]
    public string FirstName
    {
        get
        {
            return (string)base["FirstName"];
        }
        set
        {
            base["FirstName"] = value;
        }
    }
    public ConfigHander()
    { }
}
