类库调用自身所带的配置文件中的配置信息，而不是读取应用程序所带的配置信息。代码如下：
private Configuration GetConfig()
{
//获取调用当前正在执行的方法的方法的 Assembly
Assembly assembly = Assembly.GetCallingAssembly();
string path = string.Format("{0}.config", assembly.Location); if (File.Exists(path) == false)
{
string msg = string.Format("{0}路径下的文件未找到 ", path);
throw new FileNotFoundException(msg);
} try
{
ExeConfigurationFileMap configFile = new ExeConfigurationFileMap();
configFile.ExeConfigFilename = path;
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configFile, ConfigurationUserLevel.None); return config;
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}
