如何在 C# 中显示来自 gmap 的地址？

Question

我在我的项目中使用了Gmap，我想显示一个地址。

我尝试使用 BingMap、Yahoo、OpenStreet 和 googleMap。但我无法显示地址。我写了这段代码：

private void gMapControl1_MouseClick(object sender, MouseEventArgs e)
        {

                PointLatLng myPoint= gMapControl1.FromLocalToLatLng(e.X, e.Y);
// GetAddress is my Method
                var addresses = GetAddress(myPoint);

                // Display Address
                if (addresses != null)
                    richTextBox1.Text = addresses[0];
                else
                    richTextBox1.Text = "Unable To Load Address";

            }

// this is my method

 List<string> GetAddress(PointLatLng point)
        {
            List<Placemark> placemarks = null;
            gMapControl1.MapProvider = GMapProviders.OpenStreetMap;
            var statusCode = GMapProviders.OpenStreetMap.GetPlacemarks(point, out placemarks);
            if (statusCode == GeoCoderStatusCode.G_GEO_SUCCESS && placemarks != null)
            {
                List<String> addresses = new List<string>();
                foreach (var placemark in placemarks)
                {
                    addresses.Add(placemark.Address);
                }
                return addresses;
            }
            return null;
        }

每次都是在richTextBox（GoogleMapProvider）中写： "Unable To Load Address"

Google 地图需要提供个人密钥，这在某些国家（例如伊朗）由于制裁而无法获得。推荐使用完全免费的Open Street
