Generate connection string dynamically in ASP.NET MVC

问题

I am calling a stored procedure in a static class and calling that in my controller, which will generate connection string on the fly in my Asp.NET MVC project. I am calling like this:

var connection = App.connectionstring.connectionstring.connection().ToString();

Here var connection has the connection string. Now I need to use this connection and connect to database.

I followed EntityConnectionStringBuilder() approach like this:

var builder = new EntityConnectionStringBuilder();
      builder.Metadata = "res://*/MyModel.csdl|res://*/MyModel.ssdl|res://*/MyModel.msl";
      builder.Provider = "System.Data.SqlClient";
      builder.ProviderConnectionString = connection;

But I am not sure whether it's the correct implementation and also I don't know how to use this connection string in the web.config or somewhere to connect to database.

Can someone help me in this.
