I'd like to set a connection string programmatically, with absolutely no change to any config files / registry keys.
I have this piece of code, but unfortunately it throws an exception with "the configuration is read only".
ConfigurationManager.ConnectionStrings.Clear(); string connectionString = "Server=myserver;Port=8080;Database=my_db;..."; ConnectionStringSettings connectionStringSettings = new ConnectionStringSettings("MyConnectionStringKey", connectionString); ConfigurationManager.ConnectionStrings.Add(connectionStringSettings);
The problem is that I have existing code that reads the connection string from the configuration. So setting the config string manually, or through a resource, don't seem like valid options. What I really need is a way to modify the configuration programmatically.
