读取web.config中appSettings的key值

配置文件如下：

 <configuration>
  <appSettings>
    <add key="MyTxtPath" value="D:\ratedata"/>
  </appSettings>

  <connectionStrings>
    <add name="defaultConnString" connectionString="Data Source=aypt;User ID=SJJH;Password=SJJH;" providerName="System.Data.OracleClient"/>
  </connectionStrings>

</configuration>

 

调用web.config中appSettings的key值：

using System.Configuration;
string strConfigValue = ConfigurationSettings.AppSettings[MyTxtPath].ToString();

 

获取数据库配置：

string strConfigValue = System.Configuration.ConfigurationManager.ConnectionStrings["defaultConnString"].ConnectionString;
