1) 以上是webservice项目中的 web.config文件,需要读到数据库连接信息
可以直接用 string conStr = ConfigurationManager.ConnectionStrings["sqlString"].ConnectionString;
2)如果是自己新建的xml文件,也可以直接从xml中读取信息
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("config.xml");
XmlNode conNode= xmlDoc.SelectSingleNode("configuration/connectionStrings/add[@name=‘SqlString‘]");
string conn = conNode.Attributes["connectionString"];
