C# - Use Connectionstring From Web.config In Source Code File?

Mar 15, 2011

I know this might be a very basic question, but maybe thats why im having problems finding the answer. Right now I'm creating database connections in my source files by doing something like this:

SqlConnection con = new SqlConnection("Data Source=...Password=...);
SqlCommand cmd = new SqlCommand(String.Format("SELECT * FROM Table;"), con);
SqlDataReader reader = cmd.ExecuteReader();

But this means that if I choose to change databases it will be a major pain in the ass. Do you guys know how to use the connection string from a web.config file instead?

ADO.NET :: How To Use Connectionstring From Web.config

Jan 2, 2011

I have a connectionstring in my web.config <add name="HeimkinoVerbindungszeichenfolge1" connectionString="Data Source=SERVER;Initial Catalog=Heimkino;Persist Security Info=True;User ID=sa;Password=*******;"providerName="System.Data.SqlClient" />

This itself is working when using eg the SQLDataSource for a Gridview or similar.

Now I need to access this DB with different scripts and work with that database.

Eg I need to run this comand in a page_load against the DB


to remove old events from the database

For other pages I need something like


for some userauthentication things this should just create a recordset I can work with then.

Is there a way to realize this using the connectionstring in the web.config (and if so, How???)

If this will not work, how can I run such queries?

WebMatrix :: Use Database.Open For ConnectionString From Web.config?

Aug 12, 2010

As mentioned in this tutorial (http://www.asp.net/webmatrix/tutorials/5-working-with-data), I tried using my own connectionstring from web.config.

I got this error: "Format of the initialization string does not conform to specification starting at index 0."

The tutorial suggests to use: Database.OpenConnectionString("SmallBakeryConnectionString") method

Instead you should use Database.Open("ConnectionStringName").

Ref: http://cytanium.com/forums/yaf_postsm18_Connection-string-problem.aspx

The API Document is missing Database.Open method and also Database.OpenConnectionString info needs to be modified.

C# - In EF4.1 Code First - Override ConnectionString Name In Web.configuration?

Mar 23, 2011

I'm creating a multi-tenant Asp.Net MVC 3 Web app, and using EF4.1 code first for the db model.For development I'm happy to use SqlServerCE in App_Data, and for production this will move to Sql Server 2008.

Say my context is called "MyModels", by default code-first looks for a connection string called "MyModels" in Web.config. This can be told to use a file in App_Data or changed to access a database in SQL2008. All fine so far.

But because of multi-tenancy, I'd like the SqlServerCE filename to match the unique id of the tenant (so App_Data would have "client_x.sdf", "client_y.sdf"; Sql Server 2008 would have separate databases). I can't work out how to direct to these different databases.

I've tried MyModels inheriting from DbContext and supplying a connection string (using a 'placeholder' conn string in Web.config and replacing "{clientId}" with the unique id), and I've also tried setting the connection string in the MyModels constructor:

base.Database.Connection.ConnectionString = xxx;

but this never seems to work. I always get the following error:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

( it's not yet 'configured' to use SqlServerCE, and so is trying to connect to Sql Server)

Tracing the code, Database.Connection.ConnectionString hasn't been read from Web.config at this point, so I can't search and replace that, and, possibly, it's getting overwritten by the 'placeholder' conn string later in the pipeline.I reckon this must be quite straightforward and I just can't find the 'hook'.

Configuration :: How To Merge A Distribution Web.config File And An Existing Web.config File

Mar 30, 2010

I'm preparing to deploy a ASP.NET web application. The target server has already a previous version of my web application with parameters specified on the web.config file.

In the new version of this web application, the web.config file contains new sections I would like they appear into the target web.config file on the server.

However I can't find the way to merge the new web.config sections into the existing web.config file ?

Does I have to do it programmatically, or is there a tool to merge the both files during installation ? (I'm using Web Setup Project).
