That is not how you want to store connection strings. Ideally you want them in your .config file. If your connection strings are created on the fly, just just string.Format to enter the data needed for the connection string. See an example below as a solution.

Thank you
I refer to the "cnn1" and the "cnn2".

If you're asking if you can create two connections to two different databases at the same time, then yes, you can.

I question how you're doing it though, as someone else has already pointed out.

Here is how you can store your connection string in the config file and use it in your code:

<add key="ConString" value="Data Source={0};Initial Catalog={1};User ID={2};Password={3}" />

In your code behind:

string connection = (ConfigurationManager.ConnectionStrings["ConString"].ConnectionString).ToString();

SqlConnection con = new SqlConnection(string.Format(connection, datasource, database1, user_ID, pwd));
