double connectionstring in web.config

Question

У меня есть две соединительные линии в двух разных базах данных, но в той же службе данных. Вторая строка подключения предназначена для загрузки продуктов. Поэтому я могу запустить локальный сайт: http://localhost/home-1. Но если я хочу, чтобы увидеть детали продукта, например: http://localhost/catalog?GroupID=00015 я получаю эту ошибку:

System.Data.EntityException: The underlying provider failed on Open. ---> System.Data.SqlClient.SqlException: Login failed for user 'VERPLOEGEN\Niels'.

В connectionstrrings выглядит следующим образом:

<connectionStrings> 
    <add name="DataAccess_DynamicWebEntities" connectionString="metadata=res://*/DataAccess_DynamicWeb.csdl|res://*/DataAccess_DynamicWeb.ssdl|res://*/DataAccess_DynamicWeb.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=DESKTOP-UON3ACI\SQLEXPRESS;initial catalog=Dynamicweb-Verploegen-Test_new;user id='VERPLOEGEN\Niels';password='';multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" /> 
    <add name="NAV2DWservice.Properties.Settings.NAVconnectionString" connectionString="Data Source=DESKTOP-UON3ACI\SQLEXPRESS;Integrated Security=no;Initial catalog=Verploegen-Test;user=sa;password=8Bit235711" /> 
    <!-- <add connectionString="Data Source=DESKTOP-UON3ACI\SQLEXPRESS;Integrated Security=yes;Initial catalog=Verploegen-Test;user id=''" name="NAV2DWservice.Properties.Settings.NAVconnectionString" />-->

    </connectionStrings>

Hummm, что вам нужно чтобы получить конкретное значение строки подключения в вашем файле cs во время вызова запроса базы данных, поскольку вы работаете с несколькими строками подключения. это поможет вам получить желаемый результат из нужной базы данных.
