基于.net 的加载自定义配置-误操作

有时候 需要 将程序加载自定义的配置文件，除了自己写解析xml文件。内置的ConfigutionManager对象 是个不错的选项。

按照 app.config 的方式，做一个副本。然后从你的配置文件中，加载指定的配置 键值对！

 //方法1-可以读取任意位置的xml文件 
ExeConfigurationFileMap filemap = new ExeConfigurationFileMap();
            filemap.ExeConfigFilename = QuartzConfigPath; //filePath;  
            var  config = ConfigurationManager.OpenMappedExeConfiguration(filemap, ConfigurationUserLevel.None);
// 方法2 -只能读取当前应用程序域中 根目录下的文件：注意exe的含义
            //var  config = ConfigurationManager.OpenExeConfiguration(QuartzConfigPath);
