static string ConnPath AppDomain.CurrentDomain.BaseDirectory ConnOrcle.xml;
声明xml名称#xff0c;便于后续写入对应数据库参数
2、创建xml

2、创建xml
/// summary /// 创建XML节点 /// /summary /// param nameip/param /// param nameport/param /// param namesid/param /// param nameuser/param /// param namepwd/param public static void CreateXMLInform(string ip, string port, string sid, string user, string pwd) { XmlDocument xmlDoc new XmlDocument(); XmlDeclaration xmlDecl xmlDoc.CreateXmlDeclaration(1.0, utf-8, null); xmlDoc.AppendChild(xmlDecl); XmlElement xe xmlDoc.CreateElement(Conn);//创建一个Conn节点 XmlElement xc1 xmlDoc.CreateElement(ConnIP);//IP xc1.InnerText ip; xe.AppendChild(xc1); XmlElement xc2 xmlDoc.CreateElement(ConnPort);//端口 xc2.InnerText port; xe.AppendChild(xc2); XmlElement xc3 xmlDoc.CreateElement(ConnSid);//服务器名称 xc3.InnerText sid; xe.AppendChild(xc3); XmlElement xc4 xmlDoc.CreateElement(ConnUser);//用户名 xc4.InnerText user; xe.AppendChild(xc4); XmlElement xc5 xmlDoc.CreateElement(ConnPwd);//密码 xc5.InnerText pwd; xe.AppendChild(xc5); xmlDoc.AppendChild(xe); xmlDoc.Save(ConnPath); } 3、声明连接类实体 ConnEntity private string connIP;//ip地址 private string connPort;//端口 private string connSid;//服务器名称 private string connUser;//用户名 private string connPwd;//密码
4、读取xml内容并赋值给ConnEntity /// summary /// 读取XML内容赋值给连接 /// /summary /// returns/returns public static ConnEntityReadXML() { ConnEntity connentiy new ConnEntity(); if (File.Exists(ConnPath)) { XmlDocument xmlDoc new XmlDocument(); xmlDoc.Load(ConnPath); XmlNodeList list xmlDoc.SelectSingleNode(Conn).ChildNodes; connentiy.ConnIP list[0].InnerText; connentiy.ConnPort list[1].InnerText; connentiy.ConnSid list[2].InnerText; connentiy.ConnUser list[3].InnerText; connentiy.ConnPwd list[4].InnerText; } return connentiy; } 5、连接数据库测试 /// summary /// 连接数据库 /// /summary /// param nameip地址/param /// param nameport端口/param /// param namesid服务名称/param /// param nameuser用户/param /// param namepwd密码/param public static bool ConnectionTestDB(string ip, string port, string sid, string user, string pwd) { ConnOracle(ip, port, sid, user, pwd); try { //不为空 并且 是关闭或者断了的情况下才连接 if (Connection ! null (Connection.State System.Data.ConnectionState.Closed || Connection.State System.Data.ConnectionState.Broken)) { Connection.Open(); ReturnOwner Select(SELECT OWNER, TABLE_NAME FROM ALL_TAB_COMMENTS ORDER BY OWNER, TABLE_NAME); } MessageBox.Show(连接成功); return true; } catch (Exception ex) { MessageBox.Show(“连接失败请检查数据库配置参数”ex.Message.ToString()); return false; } } 6、其中调用的函数 /// /summary /// param nameip地址/param /// param nameport端口/param /// param namesid服务名称/param /// param nameuser用户/param /// param namepwd密码/param /// returnsOleDbConnection/returns private static OracleConnection ConnOracle(string ip, string port, string sid, string user, string pwd) { string connStr; connStr Data Source(DESCRIPTION (ADDRESS_LIST (ADDRESS (PROTOCOL TCP)(HOST ip )(PORT port ))) (CONNECT_DATA (SERVICE_NAME sid )));User ID user ;Password pwd ;; Connection new OracleConnection(connStr); return Connection; } 详细看源码网址及下载
