SqlCommand and DataAdapter?

[Dillinger4]

Does anyone know how many overloaded constructors the DataAdapter has? I know one of them takes an string representing an sql statment and a connection string. But does one of them take a SqlCommand object and a connection string?

I am just reading a snippet from a book which says the following:

"When using a DataAdpater with a DataSet, Command objects are used to return and modify data at the source through the DataAdapter object's SelectCommand, InsertCommand, UpdataCommand, and DeleteCommand properties."

So would i have to set one of the previous properties of the DataAdapter to a SqlCommmand object? Im not quite sure. This crappy book fails to give a code snippet. Thanks.....
