  <  Add key  =  "  Myconfig  "  Value =  "  Data Source =.; initial catalog = xbmis; user id = sa; Pwd =:  "  />  

  <  Add key  =  "  Crystaliamgecleaner-autostart  "  Value  =  "  True  " />

  <  Connectionstrings  > 

 

InProgramCentralized reference is as follows:

Use the namespace system. configuration, that is, using system. Configuration

 

 

 System. configuration. configurationmanager. configurettings [ "  Myconfig  "  ]

Get Data Source  =  .; Initial catalog  =  Xbmis; User ID  =  SA; pwd  =  :   

System. configuration. configurationmanager. connectionstrings [  "  Xbmisconnectionstring  " ]. Connectionstring

Get Data Source  =  .; Initial catalog  =  Xbmis; persist Security info  =  True; User ID  =  SA; Password  =  "     
  
Providername  =  " System. Data. sqlclient 

 

Note: The underlined part after the namespace system. configuration is referenced can be omitted.

<Etettings> is generally used to configure common values <connectionstrings>. It is generally used to configure database connections.
Not mandatory. You can write an XML file for configuration.
It is convenient here.
