Best way to set strongly typed dataset connection string at runtime?

Question

My Windows Forms application uses a strongly typed dataset created using the designer in Visual Studio. At runtime I would like to be able to select either the live or test data

Answer 1

By default the Connection property is set to be internal. This can be changed in the DataSet's designer.

1. Right-click the TableAdapter.

2. Then change the ConnectionModifier property to public.

3. You can now access the Connection property in your project.

var loginsTableAdapter = new MyDataSetTableAdapters.LoginsTableAdapter();
loginsTableAdapter.Connection.ConnectionString = _myConnectionString;
