Web.Config数据库连接及读取Web.config内容

Web.config节点:

  <connectionStrings>
    <add name="connectionString" providerName="System.Data.SqlClient" connectionString="Data Source=.;database=MemberShipDemo;Persist Security Info=True;User ID=sa;Password=123123;"/>
  </connectionStrings>

 

 

调用代码：

 

 SqlConnection con = new SqlConnection();
            con.ConnectionString = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["connectionString"].ConnectionString;
            con.Open();
            Response.Write("OK");
            con.Close();
