範例

以下程式示範如何同步呼叫 ResolveAddress 以解析市民地址。

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)
            {
                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.")

以下程式示範如何非同步呼叫 ResolveAddressAsync 以解析市民地址。

using System;
using System.Device.Location;

        static void Main(string[] args)

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

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

備註

該 CivicAddressResolver 類別提供一個實作 ICivicAddressResolver ，若位置提供者同時提供座標與市民地址資料，則該物件將基於座標的位置解析為公民地址。

建構函式

名稱 Description
CivicAddressResolver()

初始化 CivicAddressResolver 類別的新執行個體。

方法

名稱 Description
Equals(Object)

判斷指定的物件是否等於目前的物件。

(繼承來源 Object)
GetHashCode()

做為預設哈希函式。

(繼承來源 Object)
GetType()

取得目前實例的 Type。

(繼承來源 Object)
MemberwiseClone()

建立目前 Object的淺層複本。

(繼承來源 Object)
ResolveAddress(GeoCoordinate)

同步解析來自某地點的市政地址，根據緯度與經度。 此呼叫會在位址解析過程中阻擋呼叫執行緒的執行。
ResolveAddressAsync(GeoCoordinate)

從基於緯度與經度的位置非同步解析位址。 呼叫不會在位址解析過程中阻擋呼叫執行緒的執行。
ToString()

傳回表示目前 物件的字串。

(繼承來源 Object)

事件

名稱 Description
ResolveAddressCompleted

當呼叫啟動的位址解析 ResolveAddressAsync(GeoCoordinate) 完成時，會發生。
