Provides functionality for resolving a coordinate-based location to a civic address.

Assembly:  System.Device (in System.Device.dll)

System.Object
  System.Device.Location.CivicAddressResolver

Public NotInheritable Class CivicAddressResolver
	Implements ICivicAddressResolver

NameDescription
System_CAPS_pubmethodCivicAddressResolver()

Initializes a new instance of the CivicAddressResolver class.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodResolveAddress(GeoCoordinate)

Synchronously resolves a civic address from a location based on latitude and longitude. This call will block execution of the calling thread while the address is being resolved.

System_CAPS_pubmethodResolveAddressAsync(GeoCoordinate)

Resolves an address asynchronously from a location that is based on latitude and longitude. The call does not block execution of the calling thread while the address is being resolved.

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubeventResolveAddressCompleted

Occurs when the address resolution that was initiated by a call to ResolveAddressAsync completes.

The CivicAddressResolver class provides an implementation of ICivicAddressResolver that resolves a coordinate-based location to a civic address if the location provider provides both coordinates and civic address data.

The following program shows how to call ResolveAddress to resolve a civic address synchronously.

Imports System.Device.Location
Module ResolveAddressSync

    Public Sub ResolveAddressSync()
        Dim watcher As GeoCoordinateWatcher
        watcher = New System.Device.Location.GeoCoordinateWatcher(GeoPositionAccuracy.High)
        Dim started As Boolean = False
        watcher.MovementThreshold = 1.0     'set to one meter
        started = watcher.TryStart(False, TimeSpan.FromMilliseconds(1000))

        Dim resolver As CivicAddressResolver = New CivicAddressResolver()
        If started Then
            If Not watcher.Position.Location.IsUnknown Then
                Dim address As CivicAddress = resolver.ResolveAddress(watcher.Position.Location)
                If Not address.IsUnknown Then
                    Console.WriteLine("Country: {0}, Zip: {1}",
                                address.CountryRegion,
                                address.PostalCode)
                Else
                    Console.WriteLine("Address unknown.")
                End If
            End If
        Else
            Console.WriteLine("GeoCoordinateWatcher timed out on start.")
        End If
    End Sub


    Public Sub Main()

        ResolveAddressSync()
        Console.WriteLine("Enter any key to quit.")
        Console.ReadLine()
    End Sub

End Module

The following program shows how to call ResolveAddressAsync to resolve a civic address asynchronously.

Imports System.Device.Location
Module ResolveAddressSync

    Public Sub ResolveAddressSync()
        Dim watcher As GeoCoordinateWatcher
        watcher = New System.Device.Location.GeoCoordinateWatcher(GeoPositionAccuracy.High)
        Dim started As Boolean = False
        watcher.MovementThreshold = 1.0     'set to one meter
        started = watcher.TryStart(False, TimeSpan.FromMilliseconds(1000))

        Dim resolver As CivicAddressResolver = New CivicAddressResolver()
        If started Then
            If Not watcher.Position.Location.IsUnknown Then
                Dim address As CivicAddress = resolver.ResolveAddress(watcher.Position.Location)
                If Not address.IsUnknown Then
                    Console.WriteLine("Country: {0}, Zip: {1}",
                                address.CountryRegion,
                                address.PostalCode)
                Else
                    Console.WriteLine("Address unknown.")
                End If
            End If
        Else
            Console.WriteLine("GeoCoordinateWatcher timed out on start.")
        End If
    End Sub


    Public Sub Main()

        ResolveAddressSync()
        Console.WriteLine("Enter any key to quit.")
        Console.ReadLine()
    End Sub

End Module
