Examples

The following example shows how to query the city database for cities matching certain criteria:

Copy

StkCityDatabase db = new StkCityDatabase(dbDirectory, "stkCityDb");

// Create a query object and then populate it with the properties to query on.
// Regular expressions are used to query on strings.
StkCityDatabaseQuery query = new StkCityDatabaseQuery
{
    CityName = new Regex("Philadelphia"),
    // only look in PA, because there's also a New Philadelphia in Ohio
    ProvinceName = new Regex("Pennsylvania"),
};

// Get the database entries matching the query and print out the Longitude and Latitude of each.
foreach (StkCityDatabaseEntry entry in db.GetEntries(query))
{
    Console.WriteLine("{0}: Longitude {1}, Latitude {2}", entry.CityName, entry.Longitude, entry.Latitude);
}
