How to add parameters to WebMatrix Database.Query?

Using Database.Query has has made a huge improvement on readability in my code:

String Select = 'sp_getAllUsers';
WebMatrix.Data.Database DB = WebMatrix.Data.Database.Open(MyConString);
var data = DB.Query(Select);

I'd like to switch to a non-stored procedure query. The MSDN says there's an optional parameter to the Query Method, Object[], that can be passed as SQL parameters, however they don't have any further information about it.

So I have two questions:

Here's an abridged version of what I have tried:

Select = "Select * From Users Where first_name = "Foo" AND last_name = "Bar"

// Like Javascript
Object[] params = {"first_name" : "Foo"}, {"last_name" : "Bar"};

// More Like What I think it will be
Object[] Params = (String Name = "first_name", String First_Name = "Foo");

var data = DB.Query(Select, params);

All the sources I've looked at only seem to reference the old way. This is close, but he doesn't use the parameter parameter of the Query method.

Try using this syntax:

string selectCommand = "sp_getAllUsers(@0, @1)";
// selectCommand = "Select * From Users Where first_name = @0 AND last_name = @1";
...
var data = DB.Query(selectCommand, "Foo", "Bar");

Also, using a Parameter will always prevent SQL Injection as it always double quote a single quote.
