Set ConnectionString at RunTime

问题

I´m a beginner in C# programming.

I need to edit/set/change my connection string that I stored in my app.config, I'm using VS database wizard to create the queries.

If you could write the code it will be very nice :)

Something like this should get you started:

using System.Configuration;

var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var connectionStrings = config.ConnectionStrings;
foreach (var connectionString in connectionStrings.ConnectionStrings)
{
    // change connection details
}
config.Save(ConfigurationSaveMode.Modified);
