Read/write ASP. NET web. config

If you need to read and write ASP. NET web. config. See system. Web. configuration.

Before writing code, reference system. Data, system. Collection, system. Web. configuration, system. componetmodule.

Write:

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 ();
}

If you want to add objects to Web. config, You need to implement the corresponding classes:

This is because. NET Framework provides the iconfigurationsectionhandler interface.

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 ()
{}
}
