WebService的Web.config中设置连接数据库

<connectionStrings>

<add name="dbstr" connectionString="data source=HNPOWER; User Id=DCR; Password=DCR; Integrated Security=no;" />

</connectionStrings>

在WebService调用connectionString

using System.Configuration;

ConnectionStringSetting dbstr = ConfigurationManager.ConnectionStrings["dbstr"];

con.ConnectionString = dbstr.ConnectionString;

注意：webservice只能解析本地路径名。
