c# - How to configure DB connection at run time with EF 4.1 Code First -

-

i'm trying use ef 4.1 code first poco objects against legacy database. have many similar databases same schema, , need decide 1 connect @ runtime.

all examples i've seen show put connection string in app.config or web.config. won't work me since need dynamic behaviour.

what object/properties can manipulate control db settings dbcontext?

dbcontext has constructor accepts dbconnection instance, can spin using appropriate factory class.

i sort of thing in 1 of apps:

_context = new mydbcontext(     new sqlconnectionfactory(properties.settings.default.myconnectionstring)         .createconnection("databasename"));

so can read connection string @ runtime , pass sqlconnectionfactory class, give me new connection using that.

i'm not sure "databasename" parameter used in case, since it's in connection string anyway. sure, i've made sure they're same.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
