c#web.config sql2000 配置文件加获取

  <appSettings>
    
    <add key="con" value="server=.,8005;database=ddccv;uid=sa;pwd=dfcd;"></add>
  </appSettings>

数据库端口改了，需在。后加逗号 比如8005

cs代码

  public class CongfigHelper
    {
        public static string GetAppSettingsValue(string key)
        {
            ConfigurationManager.RefreshSection("appSettings");
            return ConfigurationManager.AppSettings[key] ?? string.Empty;
        }
    }
