Question

string strConn=ConfigurationManager.ConnectionStrings["TX"].ConnectionString;

ConfigurationManager.ConnectionStrings["XXX"]这个……  不会百度下么

Answer 3

試試看這個行不行        // <add name="TX" connectionString="Data Source=127.0.0.1;Initial Catalog=FF;Persist Security Info=True;User ID=sa;Password=sa" providerName="System.Data.SqlClient"/>
        //讀取你上面已經設置的節點"connectionString"
        string conn = System.Configuration.ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString;
