Connection Strings

Hi,
I'm creating an application that has to connect sequentially to different
tadabases.

I added all the connection strings to app.config and I'm itterating through
them in the following manner:
foreach (ConnectionStringSettings connStringSettings in
ConfigurationManager.ConnectionStrings)
{
........
connection = new SqlConnection(connStringSettings.ConnectionString);
.........
}

and I get:
connStringSettings.ConnectionString =
"data source=.\\SQLEXPRESS;Integrated
Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"

which is completly different from what I have in my connection string. I
don't even know where this values is comming from.

But if I do
ConfigurationManager.ConnectionStrings["MyConnString1"].ToString(),
ConfigurationManager.ConnectionStrings["MyConnString2"].ToString()

I get the correct values from app.config.

Where is the \\SQLEXPRESS connections string comming from and how can I
itterativly get the correct connection string values?

Thanks
 
Vi,

Are you using C++ in the VS2002 version or something else, without knowing
this it is helping with finding a needle in a meadow?

I'm using C# and VS.NET2005
When I'm doing
ConfigurationManager.ConnectionStrings)
{
........
connection = new SqlConnection(connStringSettings.ConnectionString);
.........
}
the first itteration has connStringSettings.ConnectionString = "data
source=.\\SQLEXPRESS;Integrated
Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"

, which I don't know where it is comming from.

The itteration 2 and 3 have the expected values that I inserted in app.config.
Thanks

Yes, I see.
I guess that this entry serves to aspnet applications for default database
when one is needed.
I would suggest you to ignore the entry
(connStringSettings.Name=="LocalSqlServer).

Vi,

This is in 2005 a normal description of a connectionstring

<connectionStrings>
<add
name="WindowsApplicationCSharp.Properties.Settings.NorthwindConnectionString"
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=C:\test1\Northwind.mdb"
providerName="System.Data.OleDb" />
</connectionStrings>

This is connected in the datasource by the synstax

\\\
this._connection = new System.Data.OleDb.OleDbConnection();
this._connection.ConnectionString =
global::TheTestApp.Properties.Settings.Default.NorthwindConnectionString;
///

Afaik can you make as much connectionstrings as you want and overrule those
in your program as much as you want by those created.

I hope this helps,

Cor

Or insert <clear/> node when appropriate:
<connectionStrings>

<clear />

</connectionStrings>

This sample will yield no connection strings at all.
