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()
{ }
}
