我正在尝试完成此异常处理程序:

if (ConfigurationManager.ConnectionStrings["ConnectionString"]==null)
{
    string pathOfActiveConfigFile = ...?
    throw new ConfigurationErrorsException(
       "You either forgot to set the connection string, or " +
       "you're using a unit test framework that looks for  "+
       "the config file in strange places, update this file : " 
       + pathOfActiveConfigFile);
}

当我使用nUnit时,这个问题似乎只发生在我身上.
