.net 读取独立的配置文件

来源：互联网发布：windows telnet服务器编辑：程序博客网时间：2024/06/04 18:35

做底层项目经常会需要保存配置信息.为了方便运维,还是把配置文件单独分离出来配置比较好 ,一个项目一个单独的独立配置文件,简单,易维护,易移植.
全部都放在一个Web.config中.拥挤不堪,找起来麻烦,看着都烦.写说明文档也麻烦的要死..还是独立配置比较清爽..

下面是读取单独配置文件的类

    public class XMLConfigRead    {        public   string ConfigPath;         public XMLConfigRead(string fileName)        {             //HttpContext.Current.Request.PhysicalApplicationPath 取得config文件路径              string dllPath = string.Empty;            try            {                //dllPath = HttpContext.Current.Request.PhysicalApplicationPath;                dllPath = HttpRuntime.AppDomainAppPath;//Web环境下 这个最稳定.应该用这个.            }            catch (Exception ex)            {                  dllPath = Path.GetDirectoryName(new Uri(this.GetType().Assembly.CodeBase).AbsolutePath); //本地应用程序的情况下.应该用这个            }             if (File.Exists(fileName))            {                ConfigPath = fileName;            }            else if (File.Exists(Path.Combine(dllPath, fileName)))            {                 ConfigPath = Path.Combine(dllPath, fileName);            }            else            {                throw new Exception("配置文件不存在，请检查");            }        }            public string ReadNodeValue (string nodename)        {            XmlDocument doc = new XmlDocument();            doc.Load(ConfigPath);            XmlNode node = doc.SelectSingleNode(nodename);            if (node.Value == null)            {                 if (node.Attributes["value"] == null)                {                    return "";                }else{                     return node.Attributes["value"].Value;                }            }else{                return node.Value;            }        }    }

把 WebSiteErrorLog.config 配置文件,直接放在网站根目录下,
读取方法是
XMLConfigRead ConfigRead = new XMLConfigRead(“WebSiteErrorLog.config”);

当然也可以把配置文件都放到config下面读取方法得改成
XMLConfigRead ConfigRead = new XMLConfigRead(“config/WebSiteErrorLog.config”);

<?xml version="1.0" encoding="utf-8" ?><ErrorLog>    <DB_DataSource value="10.90.0.0*"/>    <DB_InitialCatalog value="Log"/>    <DB_IntegratedSecurity value="false"/>    <DB_MaxPoolSize value="10000"/>    <DB_ConnectTimeout value="1"/>    <DB_UserID value="sa"/>    <DB_Password value="999"/>    <WebSiteId value="123456789"/> </ErrorLog>

//使用方法, 读取WebSiteErrorLog.config 配置文件中的配置
见下面代码

 public class StoreErrorToDB    {        XMLConfigRead ConfigRead = new XMLConfigRead("WebSiteErrorLog.config");        static SqlConnectionStringBuilder connStr ;        static string WebSiteId;        public StoreErrorToDB()        {            if (connStr == null)            {                connStr = new SqlConnectionStringBuilder();                connStr.DataSource = ConfigRead.ReadNodeValue("ErrorLog/DB_DataSource");                connStr.InitialCatalog = ConfigRead.ReadNodeValue("ErrorLog/DB_InitialCatalog");                connStr.IntegratedSecurity = Convert.ToBoolean(ConfigRead.ReadNodeValue("ErrorLog/DB_IntegratedSecurity"));                connStr.UserID = ConfigRead.ReadNodeValue("ErrorLog/DB_UserID");                connStr.Password = ConfigRead.ReadNodeValue("ErrorLog/DB_Password");                //设置最大连接池                connStr.MaxPoolSize = Convert.ToInt32(ConfigRead.ReadNodeValue("ErrorLog/DB_MaxPoolSize"));                //设置超时时间为1秒                connStr.ConnectTimeout = Convert.ToInt32(ConfigRead.ReadNodeValue("ErrorLog/DB_ConnectTimeout"));                WebSiteId = ConfigRead.ReadNodeValue("ErrorLog/WebSiteId");            }        }        public void SaveError(Error error)        {                      SqlConnection conn =  new SqlConnection(connStr.ConnectionString);                    conn.Open();                    string sql = @" INSERT INTO Error                                    (Id,WebSiteId,RequestQueryString,RequestUserAgent,RequestUserHostAddress,RequestUrl,RequestUrlReferrer,RequestRequestType,RequestHttpMethod,RequestContentEncoding,InnerException_Message,InnerException_Source,InnerException_StackTrace,InnerException_TargetSite,Message,Source,StackTrace,TargetSite,RequestCookie,RequestHeaders,RequestForms)                                     VALUES                                     (@Id,@WebSiteId,@RequestQueryString,@RequestUserAgent,@RequestUserHostAddress,@RequestUrl,@RequestUrlReferrer,@RequestRequestType,@RequestHttpMethod,@RequestContentEncoding,@InnerException_Message,@InnerException_Source,@InnerException_StackTrace,@InnerException_TargetSite,@Message,@Source,@StackTrace,@TargetSite,@RequestCookie,@RequestHeaders,@RequestForms)";
