[Development Notes]-webconfigurationmanager and configurationmanager

Writing todayProgramSome examples are occasionally discovered.CodeWebconfigurationmanager is used to obtain the configuration information in Web. config. Because the configurationmanager has been used for a long time, so I simply went into detail and made a small summary.

Msdn description:

Use Webconfigurationmanager You can access computer and application information.

use webconfigurationmanager is the preferred method for processing configuration files related to Web applications. For client applications, use configurationmanager .

 

I wonder whether it can be understood:

1. for Web applications, we recommend that you prioritize webconfigurationmanager ; however, this method is not applicable to client applications such as winform and WPF.

2. configurationmanager is applicable to web applications and client applications, but better for client applications.

 

Other sorting:

         // For client applications, use configurationmanager.          Protected   Static   String Connectionstring = configurationmanager. connectionstrings [ "  Connstr  "  ]. Tostring ();  Protected   Static   String Appconfigstring = configurationmanager. appsettings [ ""  ]. Tostring ();  // Webconfigurationmanager is the preferred method for processing configuration files related to Web applications.          Protected   Static   String Webconnectionstring = webconfigurationmanager. connectionstrings [ ""  ]. Tostring ();  Protected   Static   String Webappconfigstring = webconfigurationmanager. appsettings [ ""  ]. Tostring ();  //  Configuration nodes in Web. config: //  Connectionstrings  //  <Connectionstrings>  //  <Add name = "connstr" connectionstring = "Data Source =.; user id = sa; Pwd = 123456; database = database;"/>  //  </Connectionstrings>  //  Appsettings  //  <Deleetask>  // <Add key = "" value = ""/>  //  </Appsettings>  //  Use System. configuration. configurationmanager. deleetask[ "name"] to retrieve the value in <deleetask>.  //  In <connectionstrings>, use system. configuration. configurationmanager. connectionstrings ["name"] to retrieve the value.  //  Note:  //  System. Web. configuration does not add reference in the program by default, so direct using cannot be used.
