member this.Latitude : double with get, set

Public Property Latitude As Double

プロパティ値

Double

場所の緯度。

例外

ArgumentOutOfRangeException

Latitude が、有効範囲外の値に設定されています。

例

次の例では、 から取得された緯度と経度の値を GeoCoordinate出力します。

using System;
using System.Device.Location;

namespace LocationEvent1
{
    class Program
    {
        static void Main(string[] args)
        {
            GeoCoordinateWatcher watcher;
            watcher = new GeoCoordinateWatcher();

            watcher.PositionChanged += (sender, e) =>
            {
                var coordinate = e.Position.Location;
                Console.WriteLine("Lat: {0}, Long: {1}", coordinate.Latitude,
                    coordinate.Longitude);
                // Uncomment to get only one event.
                // watcher.Stop();
            };

            // Begin listening for location updates.
            watcher.Start();
        }
    }
}

注釈

経度の範囲は -90.0 ～ 90.0 です。 緯度は赤道から北または南の度で測定されます。 正の値は赤道の北、負の値は赤道の南です。
