利用configSource將web.config的connectionStrings移到另一個config文档中维护

参考：http://www.dotblogs.com.tw/puma/archive/2010/01/25/aspnet-connectionstring-appsetting-file-configsource.aspx

原config文件

  
    

   
     
   
      
   
     <
   
     connectionStrings
   
     >
   
      
 
   
     <
   
     add 
   
     name
   
     ="eshop"
   
      connectionString
   
     ="Data Source=(local);
 Initial Catalog=tempdb;User ID=sa;"
   
      providerName
   
     ="System.Data.SqlClient"
   
     />
   
     
 
   
     </
   
     connectionStrings
   
     >
   
     

  
    

 

  修改后

  <connectionStrings configSource ="dbConnection.config" />

 

dbConnection.config文件

 

代码

   
     

    
      
    
      <?
    
      xml version="1.0" encoding="utf-8"
    
      ?>
    
      

    
      <
    
      connectionStrings
    
      >
    
      
 
    
      <
    
      clear 
    
      />
    
      
 
    
      <
    
      add 
    
      name
    
      ="eshop"
    
       connectionString
    
      ="Data Source=(local);
Initial Catalog=tempdb;User ID=sa;"
    
       providerName
    
      ="System.Data.SqlClient"
    
      />
    
      

    
      </
    
      connectionStrings
    
      >
   
     

 

 

 appSettings 类似

<appSettings configSource="settings.config" />

 

<?xml version="1.0" encoding="utf-8"?>
<appSettings>
  <add key="Blog" value="F6 Team" />
  <add key="Name" value="puma" />
  <add key="skill" value="ASP.NET" />
</appSettings>

 

 <appSettings file="settings.config">
    <add key="Blog" value="F6 Team" />
    <add key="Name" value="puma" />
  </appSettings>

 

<?xml version="1.0" encoding="utf-8"?>
<appSettings>
  <add key="skill" value="ASP.NET" />
</appSettings>
