vs.net 2005中的ConfigurationManager

vs.net 2005中的ConfigurationManager，代替了原来的configurationsettings。用法大概如下，详细的看MSDN
读取配置：
ConfigurationManager.AppSettings["MyKey"]

读取数据库的配置（这个估计大家最经常用了）
 在web.config中
<connectionStrings>

  <add name="AppConnectionString1" connectionString="server=localhost;database=northwind;uid=sa;password=xxxx;"/>
 </connectionStrings>

在程序中如下读取：
  SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["AppConnectionString1"].ConnectionString);

GETSECTION方法：
 ConfigurationManager.GetSection("mySection")
其他的方法大概描述摘录如下：

GetWebAppSection

<?xml:namespace prefix = o />

 

With the GetWebAppSection you can get the specified section from the web applications configuration file.

 

Note: This method retrieves the specified configuration section from the configuration file located at the root folder of your Web application. If you want to retrieve the configuration section from the current Web application directory use the GetSection method.

 

RefreshSection

 

RefreshSection will refresh the specified section so next time its requested, it will be re-read from disk.

Those methods will return a Configuration class (The Configuration class has properties to get sections from the configuration file you want to edit, and by using the Save or SaveAs method, you can save the settings):

 

OpenMachineConfiguration

 

With the OpenMachineConfiguration, you configure the machine.config file.

 

OpenMappedMachineConfiguration

 

With the OpenMappedMachineConfiguration, you can open a specified configuration file.
