.Net MVC网站中配置文件的读写

四、读取配置 
也是最关系的，配置信息怎么读出来。在上面类写好后读取非常容易了,只需用WebConfigurationManager.OpenWebConfiguration("~"). GetSection()获取配置节的实例，局可以使用属性值了 

var _uploadConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~").GetSection("UploadConfig") as Ninesky.Models.Config.UploadConfig;
   //文件最大限制
   int _maxSize = _uploadConfig.MaxSize;
   //文件路径
   string _fileParth = _uploadConfig.Path ;
   string _dirName;
   //允许上传的类型
   Hashtable extTable = new Hashtable();
   extTable.Add("image", _uploadConfig.ImageExt);
   extTable.Add("flash", _uploadConfig.FileExt);
   extTable.Add("media", _uploadConfig.MediaExt);
   extTable.Add("file", _uploadConfig.FileExt);

五、写入配置
 跟读取类似，把属性值设置后save（）一下，内容就会保存到ConfigUpload.config中。 

代码如下： 

var _uploadConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~").GetSection("UploadConfig") as Ninesky.Models.Config.UploadConfig;
   //文件最大限制
   int _maxSize = _uploadConfig.MaxSize;
   _uploadConfig.FileExt = "doc,docx,xls,xlsx,ppt,htm,html,txt,zip,rar,gz,bz2";
   _uploadConfig.FlashExt = "swf,flv";
   _uploadConfig.ImageExt = "gif,jpg,jpeg,png,bmp";
   _uploadConfig.MediaExt = "swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb";
   _uploadConfig.Path = "Upload";
   _uploadConfig.CurrentConfiguration.Save();
