Contains Method (GeoExtensionMethods)

Determines if a given country or region is associated with another specified country or region.

Syntax

public static bool Contains( 
   GeoLocation region,
   GeoLocation countryOrRegion
)

Parameters

region: The primary country or region to check for association.
countryOrRegion: The country or region to verify if it has an association with the first parameter.

Return Value

True if either is associated with the other as part of the same group; otherwise, false.

Remarks

This method checks for associations such as whether a specific country is part of a broader region. For instance, GeoLocation.Bonaire being associated with GeoLocation.EUROPEAN_UNION as well as GeoLocation.CARIBBEAN. Note that regions are denoted in uppercase, while countries are in PascalCase.

Example

Demonstrate checking if a country is part of a region to apply tax rules:

var country = GeoLocation.Belgium;
             var price = 100;
             var tax = 0.0M;
             if (EUTaxApplicable(country))
             {
                 tax = 14.2M;
             }
            
             var total = (tax * price) + price;
            
             public bool EUTaxApplicable(GeoLocation country)
             {
               var vatApplicable = GeoLocation.EUROPEAN_UNION.Contains(country);
               return vatApplicable;
             }

var country = GeoLocation.CzechRepublic;
var localShipping = GeoLocation.EUROPEAN_UNION.Contains(country) && country.Contains(GeoLocation.CENTRAL_EUROPE);
var euShipping = !localShipping && GeoLocation.EUROPEAN_UNION.Contains(country);
