示例

以下示例演示如何从位置GeoCoordinate同步解析 CivicAddress 。

using System;
using System.Device.Location;
namespace ResolveAddressSync
{
    class Program
    {
        static void Main(string[] args)
        {
            ResolveAddressSync();
        }
        static void ResolveAddressSync()
        {
            GeoCoordinateWatcher watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);
            watcher.MovementThreshold = 1.0; // set to one meter
            watcher.TryStart(false, TimeSpan.FromMilliseconds(1000));

            CivicAddressResolver resolver = new CivicAddressResolver();

            if (watcher.Position.Location.IsUnknown == false)
            {
                CivicAddress address = resolver.ResolveAddress(watcher.Position.Location);

                if (!address.IsUnknown)
                {
                    Console.WriteLine("Country: {0}, Zip: {1}",
                            address.CountryRegion,
                            address.PostalCode);
                }
                else
                {
                    Console.WriteLine("Address unknown.");
                }
            }
        }
    }
}

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

以下示例演示如何从GeoCoordinate位置异步解析 CivicAddress 。

using System;
using System.Device.Location;
namespace ResolveAddressSync
{
    class AsyncProgram
    {
        public static void Main(string[] args)
        {
            ResolveAddressAsync();
        }
        static void ResolveAddressAsync()
        {
            GeoCoordinateWatcher watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);
            bool started = false;
            watcher.MovementThreshold = 1.0; // set to one meter
            started = watcher.TryStart(false, TimeSpan.FromMilliseconds(1000));

            if (started)
            {
                CivicAddressResolver resolver = new CivicAddressResolver();

                resolver.ResolveAddressCompleted += new EventHandler<ResolveAddressCompletedEventArgs>(resolver_ResolveAddressCompleted);

                if (watcher.Position.Location.IsUnknown == false)
                {
                    resolver.ResolveAddressAsync(watcher.Position.Location);
                }
            }
        }

        static void resolver_ResolveAddressCompleted(object sender, ResolveAddressCompletedEventArgs e)
        {
            if (!e.Address.IsUnknown)
            {
                Console.WriteLine("Country: {0}, Zip: {1}",
                           e.Address.CountryRegion,
                           e.Address.PostalCode);
            }
            else
            {
                Console.WriteLine("Unknown address.");
            }
        }

    }
}

Imports System.Device.Location

Module ResolveCivicAddressAsync

    Public Sub ResolveCivicAddressAsync()
        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))
        If started Then
            Dim resolver As CivicAddressResolver = New CivicAddressResolver()
            AddHandler resolver.ResolveAddressCompleted, AddressOf resolver_ResolveAddressCompleted
            If Not watcher.Position.Location.IsUnknown Then
                resolver.ResolveAddressAsync(watcher.Position.Location)
            End If
        End If

        watcher.Start()

    End Sub

    Sub resolver_ResolveAddressCompleted(ByVal sender As Object, ByVal e As ResolveAddressCompletedEventArgs)
        If Not e.Address.IsUnknown Then
            Console.WriteLine("Country: {0}, Zip: {1}",
                           e.Address.CountryRegion,
                           e.Address.PostalCode)
        Else
            Console.WriteLine("Unknown address.")
        End If
    End Sub


    Public Sub Main()

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

End Module

注解

可以使用实现 的类从 GeoCoordinate 获取位置的 ICivicAddressResolver市政地址。

如果位置源同时提供坐标数据和市政地址数据，则 CivicAddressResolver 类提供默认实现，该实现返回对应于 GeoCoordinate的市政地址。

ResolveAddress 返回 CivicAddress 当前位置的 。 如果位置源无法将坐标位置解析为市政地址， Unknown 则返回 。

构造函数

CivicAddress()	初始化 CivicAddress 类的新实例。
CivicAddress(String, String, String, String, String, String, String, String)	使用地址信息初始化 CivicAddress 类的新实例。

字段

Unknown

表示一个不包含任何数据的 CivicAddress。

属性

AddressLine1	获取或设置第一行地址。
AddressLine2	获取或设置第二行地址。
Building	获取或设置大楼名称或楼号。
City	获取或设置城市名称。
CountryRegion	获取或设置位置所在的国家/地区。
FloorLevel	获取或设置位置所在的楼层。
IsUnknown	获取一个值，该值指示 CivicAddress 是否包含数据。
PostalCode	获取或设置位置的邮政编码。
StateProvince	获取或设置位置所在的省/直辖市/自治区。

方法

Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示当前对象的字符串。 (继承自 Object)
