Good afternoon, I have encountered a problem to choose from two connection strings using C# and Linq to Entities. Currently I have two connection strings which are:

XML

<add name="GameHutDBEntities1" connectionString="metadata=res://*/GameHutModel.csdl|res://*/GameHutModel.ssdl|res://*/GameHutModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=EMMANUEL-PC\SQLEXPRESS;Initial Catalog=GameHutDB;user id=GameHutAdmin; password=123;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
    <add name="GameHutDBEntities2" connectionString="metadata=res://*/GameHutModel.csdl|res://*/GameHutModel.ssdl|res://*/GameHutModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=EMMANUEL-PC\SQLEXPRESS;Initial Catalog=GameHutDB;user id=test; password=1234;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

I have two roles which are Admin and Clerk. How can I allow the admin to login with the first connection string and the clerk will login with the second connection string?

Thanks!!

Solution 1

The ObjectContext[^] object has a overridden constructor that takes the connection string name. You would just need to use it within your code to construct the context based on the user role.

I have improved my previous answer but still the status "Deleted", anyway i am re-posting my answer:

Navigate experts answers:

EF and change of server (connection string)
Determine connection string based on environment, while using Entity Framework
Get Entity Framework connection string from alternate location?

NB: If anyone needs to delete the answer again, let me know the reason first, so that we can go through a good discussion.
