Asp.net reads the web. config file

The Helper home (www.bkjia.com) Tutorial in asp.net will always encounter the need to read the configuration file, usually to read the database connection string, this simple and practical ConfigurationManager. connectionStrings ["OMPDBConn"]. connectionString is enough, but reading a node like authentication is a little troublesome.

One method described in the web configuration file in the sdk is to use System. web. configuration. webConfigurationManager. openMachineConfiguration () to obtain a Configuraton object, which is web. config description.

Note that when calling this OpenMachineConfiguration () function, you must note that if you enter a string. empty, the default configuration file of asp.net is read, which is displayed on my machine:

C: \ Windows \ Microsoft. NET \ Framework \ v2.0.50727 \ Config \ web. config; if "/" is entered, the configuration file of the wwwroot root directory is read, which is generally: C: \ inetpub \ wwwroot \ web. config. that is to say, if you want to read a program that does not follow the directory, you need to pay special attention to this path.
